Humboldt (1850):
All formations are, therefore, common to every quarter of the
globe and assume the like forms. Everywhere basalt rises in
twin mountains and truncated cones… Thus, too, similar
vegetable forms, as pines and oaks, alike crown the mountain
declivities of Sweden and those of the most southern portion of
Mexico”
“The azure of the sky, the effects of light and shade, the haze
floating on the distant horizon, the forms of animals, the
succulence of plants, the bright glossy surface of the leaves, the
outlines of mountains, all combine to produce the elements on
which depends the impression of any one region.” “Swiss
scenery… Italian sky”
“”Observation of individual parts of trees or grass is by no
means to be considered plant geography… rather, plant
geography traces the connections and relations by which all

repeated 3 -4 times at 1-minute intervals. The animals used

already taken some important steps in that direction.

Linnaeus’ herbarium cabinet: a piece
of furniture and its function

The Swedish 18th-century naturalist Carolus (Carl)
Linnaeus is habitually credited with laying the foun-
dations of modern taxonomy through the invention of
binominal nomenclature. However, another innovation
of Linnaeus’ has largely gone unnoticed. He seems to
have been one of the first botanists to leave his
herbarium unbound, keeping the sheets of dried plants
separate and stacking them in a purpose built-cabinet.
Understanding the significance of this seemingly
mundane and simple invention opens a window onto
the profound changes that natural history underwent in
the 18th century.
Introduction
In December 1783, Sara Elisabeth Moræa, widow of the
famous Swedish naturalist Carolus (Carl) Linnaeus,
wrote to Sir Joseph Banks, then president of the Royal
Society, offering to sell him her husband’s natural history
collection for the price of 1000 guineas. Banks did not buy
it himself, but advised James Edward Smith – a member
of a well-to-do family of wool merchants from Norwich and
amateur botanist – to do so [1].
Linnaeus’ collection reached Smith in October 1784.
Among manuscripts, letters, index cards, books, minerals,
dried fishes and reptiles, and transfixed insects, the
collection included three cabinets stacked with sheets of
paper (Figure 1). Each sheet displayed a dried plant – this
was Linnaeus’ herbarium, and it contained a total of about
14 000 specimens. Two of the three cabinets that Smith
purchased were returned to Sweden in 1938, although the
Linnean Society retained their original contents [2].
Emptied of the herbarium sheets that once occupied
their shelves, they are now mere showpieces in a little
museum adjacent to the old botanical garden of Uppsala
that illustrates the atmosphere in which Linnaeus once
lived and worked. Today, the collection of specimens is
preserved in a temperature- and humidity-controlled
store beneath Burlington house in London – the seat of
the Linnean Society founded by Smith in 1788. There they
form the material starting point for the work of
taxonomists, serving as ‘type’ specimens for the 5900
plant and 4378 animal species that Linnaeus identified
and named in his Species Plantarum and Systema
Naturae, respectively.
The separation of the cabinets from the herbarium
sheets they originally contained has destroyed the unity of

what for Linnaeus was a single tool for scrutinizing the
‘natural order’ of the plant world. Today, plant taxono-
mists advance their classifications on the basis of the type
method. Each species is defined by reference to a single
specimen, the so-called ‘holotype’, which is then preserved
in a natural history museum to be accessible for
later revisions.
However, historians have established that this was not
the method Linnaeus himself employed. The type method
was the result of a protracted and often bitter fight over
authority in natural history, which took place in the first
half of the 19th century and was only resolved by the
adoption of international codes of nomenclature in 1842
(for zoology) and 1867 (for botany) [3]. The result of these
developments was that authority for the definition of
species shifted, in a sense, from people and their ideas
about species to specimens and the rules that taxonomists
use to handle them – a ‘metaphysics in action’, as historian
of science Lorraine Daston recently put it [4].
But if the type method was not how Linnaeus
determined species, how did he do it? This is an
interesting question for three reasons. First, modern-day
botanists need some understanding of the methods
Linnaeus employed when naming and defining species
because they are obliged to decide, artificially and in
retrospect, which of Linnaeus’ many specimens might
have been the type specimen described in Species
Plantarum [5]. Second, Linnaeus played a key role in
the history of biological ideas by defining the quest for a
‘natural system’ as the main task of naturalists [6]. Third,
Linnaeus was at the heart of a large-scale social
transformation in which the activity of naturalists
reached a truly global scale [7]. A look into his herbarium
cabinet, restored to life by imagining it at work, can open a
window onto the profound changes that natural history
underwent in the 18th century.
Making a herbarium
The Philosophia Botanica, a botany textbook that
Linnaeus based on the lectures he gave at the University
of Uppsala, contains careful instructions on how to create
a herbarium [8]. Linnaeus described how plants should be
collected, dried, pressed and glued onto paper, including
such details as what materials and glue to use. These
instructions were an attempt to standardize botanical
procedures and erase the habits and whims of
individual collectors.

In drawing up these instructions, Linnaeus was
following a long tradition dating back to the Italian Luca
Ghini, who was professor for medicine and botany at the
University of Pisa during the 16th century and is usually
credited with the invention of the herbarium [9].
Compared to earlier collectors, however, Linnaeus’
instructions contained a decisive innovation. Tradition-
ally, several specimens might be glued in a decorative
arrangement on a single sheet of paper (Figure 2). These
sheets were then bound into volumes, stored in a library
and cited like books. Specimens were thus placed into a
fixed order from which they could not be removed without
destroying the herbarium or even the specimens. Lin-
naeus, by contrast, advised readers of the Philosophia
Botanica to mount just one specimen per sheet and refrain
from binding them together.
For storage of the mounted specimens, Linnaeus
suggested a purpose-built cabinet and gave illustrated
guidance on how to construct it (Figure 3). These
instructions correspond exactly to the three cabinets
that Linnaeus possessed. These are rather plain in design
– only one of them was adorned with two rows of leaf
impressions on the outside of the doors. The doors open
onto two narrow columns of shelves and it appears that at
least one of the cabinets that returned to Sweden was also
equipped with a dense, parallel series of horizontal slits
covering its inner walls, into which the shelves supporting
the herbarium sheets could be inserted at variable

distances [10]. It is impossible to know if these were part of
the original design or were added later. However, this
detail indicates that the number of shelves and distances
between them could be changed easily, either to accom-
modate new material or to rearrange the collection as a
whole. Therefore, although the herbarium of Linnaeus
brought his specimens into an order, individual sheets
could easily be inserted at any place, removed at any time
and reinserted again anywhere in the collection: the
herbarium essentially functioned as a filing cabinet.
In contrast to the bound volumes of older herbaria, the
order Linnaeus’ herbarium cabinet brought to his
collection was not fixed and perpetual. It was designed
to accommodate the steady arrival of new material and
enabled its user, in principle at least, to repeatedly
rearrange that material. This was clearly important for
Linnaeus. While staying in the Netherlands from
1735–1738 he received several herbarium sheets from
George Clifford, a former director of the Dutch East India
Company whose vast plant collection Linnaeus was
curator of in 1737. These sheets had small prints mounted
Figure 4. The type specimen of Helianthus strumosus L. This is
one of the
specimens that reached Linnaeus’ herbarium from George
Clifford. These were
ornately decorated with the print of a vase (visible at the bottom
of the image) that
Linnaeus cut through when adapting the size of the sheets to his
herbarium cabinet.

onto them, creating the impression that the plant speci-
mens they carried grew from a vase. Linnaeus cut these
sheets down to a size that would fit into his cabinet, in
some instances cutting right through the ‘vase’ (Figure 4).
The internal mobility of his herbarium was apparently of
greater importance to Linnaeus than any aesthetic value
that the individual sheets or the collection as a whole
might possess.
The natural order of plants
How did Linnaeus use his herbarium? Some clues lie in
the Philosophia Botanica, where he described how to set
up what he called ‘natural’ definitions of plant species and
genera. Traditionally, plant species and genera had been
defined by the method of logical division: this method
consisted in assigning a species to its genus (or a genus to
its ‘order’) and establishing a single character by which it
could be distinguished from its congeners [11]. Linnaeus
believed that this method was insufficient and called the
definitions and taxonomic systems that resulted from it
‘artificial’. Such definitions, he reasoned, needed revision
whenever a new species was discovered; there was no
guarantee that characters used to distinguish congeners
would work for newly discovered species.
By contrast, natural definitions, or ‘natural characters’
as Linnaeus also called them, were more descriptive. They
assembled all possible traits of a species or genus, not just
a few selected for their diagnostic value. The method that
Linnaeus proposed for establishing natural characters
was simple and straightforward. The botanist started with
a ‘first species’ (prima species) represented by a garden
exemplar, a herbarium specimen or a drawing, and drew
up a full description of its morphology. In a series of
further steps, additional representative specimens were
gathered one by one. Characters that deviated from the
original were then cancelled from the description. What
was left was the set of characters that had proved to be
‘constant’.
In some instances Linnaeus referred to this compara-
tive method as ‘collation’, a legal term for the word-by-
word comparison of an original document with its copy.
This metaphor can be taken literally. Garden exemplars
were seasonal, and plant drawings often unreliable. The
herbarium, on the other hand, provided a reliable source
of concrete evidence: stable and ready at hand throughout
the year. Linnaeus’ description of collation enables us to
imagine how he actually used his herbarium. In setting up
natural characters, he would first take out one herbarium
sheet, and then adduce others to compare the mounted
specimens systematically, point-by-point, as if comparing
two texts.
The design of the herbarium cabinet thus enabled
Linnaeus to put together any set of specimens at a time for
the purpose of collation. As a result, the relations among
plant forms represented by natural characters trans-
cended the local differences exhibited, say, by two speci-
mens permanently fixed on one and the same herbarium
sheet. The ‘natural system’ of plants, as Linnaeus saw it,
consisted of a two-dimensional web of relations in which
‘all plants exhibit their contiguities on either side,
like territories on a geographical map.’ Each species

represented by a specimen in Linnaeus’ herbarium was
defined by the affinities it exhibited with respect to all the
other specimens in the collection. The potential for a
complete permutation of specimens, which the herbarium
cabinet offered in principle, enabled a global represen-
tation of taxonomic affinities [12]. Accordingly, it was the
herbarium in its totality, rather than arbitrary type
specimens, which served as a tool in the determination
of plant species and genera.
The social order of botany
The enormous numbers of plant specimens that Linnaeus’
three cabinets accommodated were accrued from a world-
wide network of botanists, professionals as well as
amateurs, with whom Linnaeus exchanged seeds and
specimens [13]. Two parties played a crucial role in this
network. First were the botanists presiding over major
European botanical gardens – contacts Linnaeus had
primarily established during the time he spent in The
Netherlands. They included Johann Jacob Dillen in
Oxford, Antoine and Bernard Jussieu in Paris, Adriaan
van Royen in Leyden, Albrecht von Haller in Göttingen
and Johann Georg Gmelin in St Petersburg [14]. It seems
likely that it was as curator of Clifford’s botanical garden
that Linnaeus found the inspiration for the peculiar
construction of his herbarium. None of the surviving
specimens from Clifford’s collection seems to have been
bound and there were a few other botanists in the
Netherlands that kept their specimens on loose sheets,
although this might already have been due to Linnaeus’
influence [15].
Second were collectors at the periphery of the known
botanical world that Linnaeus engaged for his purposes.
His students, in particular, were a major source for seeds
and specimens as they travelled the world with support
from the Royal Academy of Sciences in Stockholm or the
Swedish East India Company: Per Kalm travelled North
America from 1749–1751, Daniel Solander accompanied
the first circumnavigation of the globe with James Cook
and Carl Peter Thunberg’s voyage from 1770–1779 took
him as far as Sri Lanka and Japan [16]. Linnaeus’ own
garden at Uppsala functioned as a hub in this two-tiered
system of exchange. The acquisition of ‘new species’ from
peripheral collectors strengthened his position as an
exchange partner in the European system of large
botanical gardens, whereas the material he exchanged
with these centres enabled him to compensate his
exchange partners at the periphery through the provision
of seeds and specimens of species they lacked in their own
collections [17].
The botanical garden in Uppsala thus became a place
not only dedicated to the local production of specimens,
but also to their reproduction for purposes of exchange. Its
wealth was not determined by the splendour of the
individual plants inhabiting it, but rather through the
number of identically reproducing species that could be
harvested for seeds and specimens and then offered in
exchanges with other botanists. This is reflected in the
characterization of two kinds of botanist Linnaeus
distinguished in the Philosophia Botanica – the collectors
who were ‘primarily concerned with the number of species
www.sciencedirect.com
of vegetables’ and the systematists who ‘arranged the
plants in particular ranks’. The role of collectors was not
merely to accumulate, however, and nor were the
systematists just passively ordering material. When
Linnaeus discussed the way in which natural characters
of plant genera should best be set up, he curiously
conflated both the role of collector and systematist: it is
only ‘the most accomplished botanist, and he alone [who]
achieves the best natural character; for it will be made by
the agreement of the greatest number of species; for every
species excludes some superfluous feature’ [18].
This enigmatic statement, typical of Linnaeus’ con-
densed style of writing, begins to make sense when we
recall his method of collation. This consisted of the
comparison of two or more specimens and the removal of
all varying characters from a description produced from
some ‘first species’. Each ‘new’ species entering collation
would thus indeed ‘exclude superfluous features’ from the
natural character, and the latter would only collect those
traits that enable diverse specimens to stand in for each
other, or by which they could be judged to be copies or
duplicates. The ‘most accomplished botanist’ – in his usual
self-confident way, Linnaeus was clearly thinking of
himself – was thus not simply the botanist with the
largest collection but also the one who, by collation, could
determine the specimens that were ‘duplicates’ and
therefore free to be exchanged [19]. Managing a large
collection for the purposes of comparison and exchange
was a complex task. Linnaeus’ herbarium cabinet,
designed for the flexible realization of any set of
exemplars, was clearly an effective tool for quickly
checking which species were already represented in his
collection, and which were not and thus (to him at
least) new.
Another feature of the herbarium cabinets emphasizes
their function. The shelves were arranged according to
Linnaeus’ famous sexual system, which divided the plant
realm into 24 classes according to the number and position
of stamina and pistils. Although this might appear to
embrace a relatively fixed arrangement of the collection,
Linnaeus made it clear that this enabled him to ‘pull out
and produce [any plant] without delay’. The methodical
arrangement of specimens according to the sexual system
served as a retrieval system for previously gathered
information, and was therefore an arbitrary device that
did not represent any natural order. ‘Others’, as Linnaeus
therefore emphasized in the Philosophia Botanica, ‘may
arrange [their herbarium] according to any other system,
observing what should be observed’.
The agitated background of 18th century taxonomy
According to some famous remarks that Michel Foucault
made in his Order of Things, 18th-century natural history
was profoundly shaped by ‘herbaria, natural history
cabinets, and botanical gardens.’ These institutions
formed the ‘timeless rectangle’ of 18th century taxo-
nomies, in which ‘beings presented themselves side by
side with their visible surfaces, without any commentary
and surrounding language, approaching each other by
their common traits, and thus virtually analyzed, bearers
of their sole names’ [20]. To some, this might suggest an

18th-century mentality that preferred order and stability
above diversity and variation, measurement above experi-
ment: a static and tendentiously conservative outlook.
Indeed, Carl Linnaeus has often enough been portrayed as
the prototypical protagonist of this mind-set [21].
However, Linnaeus’ preoccupation with a taxonomy of
‘constant’ characters resulted from his engagement in a
dynamic practice of transplantation and exchange, which
had deep roots in the rapid and ongoing globalization of
European economies [22]. Furthermore, it should not be
ignored that his taxonomic works were published in
several editions: Linnaeus authorized two editions of the
Species Plantarum during his lifetime; the Genera
Plantarum went into six; and the Systema Naturae
into 12, growing from a 12-paged folio volume into
three octavo volumes of approximately 1500 pages.
Taxonomy had become the art of revising prior classifi-
cations in the light of ‘new’ species, and Linnaeus’
herbarium cabinet was perfectly designed to accommodate
this progressive movement.

History 281: History of Science
Midterm Examination
Spring 2015
Read and follow the instructions carefully.
Write your answers in essay form. Draw specifically on the
lectures, readings, and discussions in writing your answers.
Write a brief introduction and conclusion and be sure to answer
all parts of the question. Be sure to answer the question
actually asked, not one you wish had been asked. Your answers
will be graded on organization, clarity, specificity, and creative
insight.
Group I (50%)
Answer one of the following questions.
1. Historians of Science have compared the role of science in
the French Revolution to the mobilization of physicists during
World War II to the Manhattan Project leading to the first
atomic bomb. Do you think such comparison is reasonable?
How did the involvement of scientists and engineers with the
state during those revolutionary years contributed to mold the
engineering profession in France in the following decades?
2. What material resources did Linnaeus need to undertake his
studies in Botany? What do we learn from looking in detail at
the spaces Linnaeus worked in? In particular what does
furniture have to tell us about botany as practiced by Linnaeus?
Group 2 (50%)
Answer one of the following questions.
1. Consider the following painting by F. E. Church. How is the
image of nature here represented related to the figure of the
romantic scientist Alexander von Humboldt? Why were people
in the Americas so interested in Humboldt’s views on nature?
Frederic Edwin Church, The Heart of the Andes, 1859
2. Consider the following picture of a laboratory in the Lisbon
Bacteriological Institute. Why were scientists using rabbits in
their experiments? How can one relate the growing use of non-
human animals in bacteriology with the rise of the laboratory as
a crucial space for the life sciences? Can you refer to other non-
human animals present in a bacteriological institute?
Lisbon Bacteriology Institute, 1900

Empires and Revolutions/LinnaeusCabinet.pdf Linnaeus’ herbarium cabinet: a piece of furniture and its function Staffan Müller-Wille ESRC Centre for Genomics in Society, University of Exeter, Amory Building, Rennes Drive, Exeter, Devon, UK EX4 4RJ The Swedish 18th-century naturalist Carolus (Carl) Linnaeus is habitually credited with laying the foun- dations of modern taxonomy through the invention of binominal nomenclature. However, another innovation of Linnaeus’ has largely gone unnoticed. He seems to have been one of the first botanists to leave his herbarium unbound, keeping the sheets of dried plants
  • 13. separate and stacking them in a purpose built-cabinet. Understanding the significance of this seemingly mundane and simple invention opens a window onto the profound changes that natural history underwent in the 18th century. Introduction In December 1783, Sara Elisabeth Moræa, widow of the famous Swedish naturalist Carolus (Carl) Linnaeus, wrote to Sir Joseph Banks, then president of the Royal Society, offering to sell him her husband’s natural history collection for the price of 1000 guineas. Banks did not buy it himself, but advised James Edward Smith – a member of a well-to-do family of wool merchants from Norwich and amateur botanist – to do so [1]. Linnaeus’ collection reached Smith in October 1784. Among manuscripts, letters, index cards, books, minerals, dried fishes and reptiles, and transfixed insects, the collection included three cabinets stacked with sheets of paper (Figure 1). Each sheet displayed a dried plant – this was Linnaeus’ herbarium, and it contained a total of about 14 000 specimens. Two of the three cabinets that Smith purchased were returned to Sweden in 1938, although the Linnean Society retained their original contents [2]. Emptied of the herbarium sheets that once occupied their shelves, they are now mere showpieces in a little museum adjacent to the old botanical garden of Uppsala that illustrates the atmosphere in which Linnaeus once lived and worked. Today, the collection of specimens is
  • 14. preserved in a temperature- and humidity-controlled store beneath Burlington house in London – the seat of the Linnean Society founded by Smith in 1788. There they form the material starting point for the work of taxonomists, serving as ‘type’ specimens for the 5900 plant and 4378 animal species that Linnaeus identified and named in his Species Plantarum and Systema Naturae, respectively. The separation of the cabinets from the herbarium sheets they originally contained has destroyed the unity of Corresponding author: Müller-Wille, S. ([email protected]).

All rights reserved what for Linnaeus was a single tool for scrutinizing the ‘natural order’ of the plant world. Today, plant taxono- mists advance their classifications on the basis of the type method. Each species is defined by reference to a single specimen, the so-called ‘holotype’, which is then preserved in a natural history museum to be accessible for later revisions. However, historians have established that this was not the method Linnaeus himself employed. The type method was the result of a protracted and often bitter fight over authority in natural history, which took place in the first half of the 19th century and was only resolved by the adoption of international codes of nomenclature in 1842 (for zoology) and 1867 (for botany) [3]. The result of these developments was that authority for the definition of species shifted, in a sense, from people and their ideas about species to specimens and the rules that taxonomists use to handle them – a ‘metaphysics in action’, as historian of science Lorraine Daston recently put it [4].
  • 15. But if the type method was not how Linnaeus determined species, how did he do it? This is an interesting question for three reasons. First, modern-day botanists need some understanding of the methods Linnaeus employed when naming and defining species because they are obliged to decide, artificially and in retrospect, which of Linnaeus’ many specimens might have been the type specimen described in Species Plantarum [5]. Second, Linnaeus played a key role in the history of biological ideas by defining the quest for a ‘natural system’ as the main task of naturalists [6]. Third, Linnaeus was at the heart of a large-scale social transformation in which the activity of naturalists reached a truly global scale [7]. A look into his herbarium cabinet, restored to life by imagining it at work, can open a window onto the profound changes that natural history underwent in the 18th century. Making a herbarium The Philosophia Botanica, a botany textbook that Linnaeus based on the lectures he gave at the University of Uppsala, contains careful instructions on how to create a herbarium [8]. Linnaeus described how plants should be collected, dried, pressed and glued onto paper, including such details as what materials and glue to use. These instructions were an attempt to standardize botanical procedures and erase the habits and whims of individual collectors.

  • 17. 1938 – image reproduced courtesy of the Linnaean Society of London. Review Endeavour Vol. 30 No. 2 June 2006 61 In drawing up these instructions, Linnaeus was following a long tradition dating back to the Italian Luca Ghini, who was professor for medicine and botany at the University of Pisa during the 16th century and is usually credited with the invention of the herbarium [9]. Compared to earlier collectors, however, Linnaeus’ instructions contained a decisive innovation. Tradition- ally, several specimens might be glued in a decorative arrangement on a single sheet of paper (Figure 2). These sheets were then bound into volumes, stored in a library and cited like books. Specimens were thus placed into a fixed order from which they could not be removed without destroying the herbarium or even the specimens. Lin- naeus, by contrast, advised readers of the Philosophia Botanica to mount just one specimen per sheet and refrain from binding them together. For storage of the mounted specimens, Linnaeus suggested a purpose-built cabinet and gave illustrated guidance on how to construct it (Figure 3). These instructions correspond exactly to the three cabinets that Linnaeus possessed. These are rather plain in design – only one of them was adorned with two rows of leaf impressions on the outside of the doors. The doors open onto two narrow columns of shelves and it appears that at least one of the cabinets that returned to Sweden was also equipped with a dense, parallel series of horizontal slits covering its inner walls, into which the shelves supporting the herbarium sheets could be inserted at variable www.sciencedirect.com http://www.sciencedirect.com

It is impossible to know if these were part of the original design or were added later. However, this detail indicates that the number of shelves and distances between them could be changed easily, either to accom- modate new material or to rearrange the collection as a whole. Therefore, although the herbarium of Linnaeus brought his specimens into an order, individual sheets could easily be inserted at any place, removed at any time and reinserted again anywhere in the collection: the herbarium essentially functioned as a filing cabinet. In contrast to the bound volumes of older herbaria, the order Linnaeus’ herbarium cabinet brought to his collection was not fixed and perpetual. It was designed to accommodate the steady arrival of new material and enabled its user, in principle at least, to repeatedly rearrange that material. This was clearly important for Linnaeus. While staying in the Netherlands from 1735–1738 he received several herbarium sheets from George Clifford, a former director of the Dutch East India Company whose vast plant collection Linnaeus was curator of in 1737. These sheets had small prints mounted Figure 4. The type specimen of Helianthus strumosus L. This is one of the
  • 19. specimens that reached Linnaeus’ herbarium from George Clifford. These were ornately decorated with the print of a vase (visible at the bottom of the image) that Linnaeus cut through when adapting the size of the sheets to his herbarium cabinet. Image (sheet no. 1024.7 of the Linnean herbarium) reproduced courtesy of the Linnaean Society of London. www.sciencedirect.com onto them, creating the impression that the plant speci- mens they carried grew from a vase. Linnaeus cut these sheets down to a size that would fit into his cabinet, in some instances cutting right through the ‘vase’ (Figure 4). The internal mobility of his herbarium was apparently of greater importance to Linnaeus than any aesthetic value that the individual sheets or the collection as a whole might possess. The natural order of plants How did Linnaeus use his herbarium? Some clues lie in the Philosophia Botanica, where he described how to set up what he called ‘natural’ definitions of plant species and genera. Traditionally, plant species and genera had been defined by the method of logical division: this method consisted in assigning a species to its genus (or a genus to its ‘order’) and establishing a single character by which it could be distinguished from its congeners [11]. Linnaeus believed that this method was insufficient and called the
  • 20. definitions and taxonomic systems that resulted from it ‘artificial’. Such definitions, he reasoned, needed revision whenever a new species was discovered; there was no guarantee that characters used to distinguish congeners would work for newly discovered species. By contrast, natural definitions, or ‘natural characters’ as Linnaeus also called them, were more descriptive. They assembled all possible traits of a species or genus, not just a few selected for their diagnostic value. The method that Linnaeus proposed for establishing natural characters was simple and straightforward. The botanist started with a ‘first species’ (prima species) represented by a garden exemplar, a herbarium specimen or a drawing, and drew up a full description of its morphology. In a series of further steps, additional representative specimens were gathered one by one. Characters that deviated from the original were then cancelled from the description. What was left was the set of characters that had proved to be ‘constant’. In some instances Linnaeus referred to this compara- tive method as ‘collation’, a legal term for the word-by- word comparison of an original document with its copy. This metaphor can be taken literally. Garden exemplars were seasonal, and plant drawings often unreliable. The herbarium, on the other hand, provided a reliable source of concrete evidence: stable and ready at hand throughout the year. Linnaeus’ description of collation enables us to imagine how he actually used his herbarium. In setting up natural characters, he would first take out one herbarium sheet, and then adduce others to compare the mounted specimens systematically, point-by-point, as if comparing two texts. The design of the herbarium cabinet thus enabled
  • 21. Linnaeus to put together any set of specimens at a time for the purpose of collation. As a result, the relations among plant forms represented by natural characters trans- cended the local differences exhibited, say, by two speci- mens permanently fixed on one and the same herbarium sheet. The ‘natural system’ of plants, as Linnaeus saw it, consisted of a two-dimensional web of relations in which ‘all plants exhibit their contiguities on either side, like territories on a geographical map.’ Each species http://www.sciencedirect.com tiagosaraiva Highlight tiagosaraiva Highlight tiagosaraiva Highlight tiagosaraiva Highlight tiagosaraiva Highlight tiagosaraiva Highlight tiagosaraiva Highlight tiagosaraiva Highlight

The potential for a complete permutation of specimens, which the herbarium cabinet offered in principle, enabled a global represen- tation of taxonomic affinities [12]. Accordingly, it was the herbarium in its totality, rather than arbitrary type specimens, which served as a tool in the determination of plant species and genera. The social order of botany The enormous numbers of plant specimens that Linnaeus’ three cabinets accommodated were accrued from a world- wide network of botanists, professionals as well as amateurs, with whom Linnaeus exchanged seeds and specimens [13]. Two parties played a crucial role in this network. First were the botanists presiding over major European botanical gardens – contacts Linnaeus had primarily established during the time he spent in The Netherlands. They included Johann Jacob Dillen in Oxford, Antoine and Bernard Jussieu in Paris, Adriaan van Royen in Leyden, Albrecht von Haller in Göttingen and Johann Georg Gmelin in St Petersburg [14]. It seems likely that it was as curator of Clifford’s botanical garden that Linnaeus found the inspiration for the peculiar construction of his herbarium. None of the surviving specimens from Clifford’s collection seems to have been bound and there were a few other botanists in the Netherlands that kept their specimens on loose sheets, although this might already have been due to Linnaeus’
  • 23. influence [15]. Second were collectors at the periphery of the known botanical world that Linnaeus engaged for his purposes. His students, in particular, were a major source for seeds and specimens as they travelled the world with support from the Royal Academy of Sciences in Stockholm or the Swedish East India Company: Per Kalm travelled North America from 1749–1751, Daniel Solander accompanied the first circumnavigation of the globe with James Cook and Carl Peter Thunberg’s voyage from 1770–1779 took him as far as Sri Lanka and Japan [16]. Linnaeus’ own garden at Uppsala functioned as a hub in this two-tiered system of exchange. The acquisition of ‘new species’ from peripheral collectors strengthened his position as an exchange partner in the European system of large botanical gardens, whereas the material he exchanged with these centres enabled him to compensate his exchange partners at the periphery through the provision of seeds and specimens of species they lacked in their own collections [17]. The botanical garden in Uppsala thus became a place not only dedicated to the local production of specimens, but also to their reproduction for purposes of exchange. Its wealth was not determined by the splendour of the individual plants inhabiting it, but rather through the number of identically reproducing species that could be harvested for seeds and specimens and then offered in exchanges with other botanists. This is reflected in the characterization of two kinds of botanist Linnaeus distinguished in the Philosophia Botanica – the collectors who were ‘primarily concerned with the number of species www.sciencedirect.com of vegetables’ and the systematists who ‘arranged the plants in particular ranks’. The role of collectors was not
  • 24. merely to accumulate, however, and nor were the systematists just passively ordering material. When Linnaeus discussed the way in which natural characters of plant genera should best be set up, he curiously conflated both the role of collector and systematist: it is only ‘the most accomplished botanist, and he alone [who] achieves the best natural character; for it will be made by the agreement of the greatest number of species; for every species excludes some superfluous feature’ [18]. This enigmatic statement, typical of Linnaeus’ con- densed style of writing, begins to make sense when we recall his method of collation. This consisted of the comparison of two or more specimens and the removal of all varying characters from a description produced from some ‘first species’. Each ‘new’ species entering collation would thus indeed ‘exclude superfluous features’ from the natural character, and the latter would only collect those traits that enable diverse specimens to stand in for each other, or by which they could be judged to be copies or duplicates. The ‘most accomplished botanist’ – in his usual self-confident way, Linnaeus was clearly thinking of himself – was thus not simply the botanist with the largest collection but also the one who, by collation, could determine the specimens that were ‘duplicates’ and therefore free to be exchanged [19]. Managing a large collection for the purposes of comparison and exchange was a complex task. Linnaeus’ herbarium cabinet, designed for the flexible realization of any set of exemplars, was clearly an effective tool for quickly checking which species were already represented in his collection, and which were not and thus (to him at least) new. Another feature of the herbarium cabinets emphasizes their function. The shelves were arranged according to
  • 25. Linnaeus’ famous sexual system, which divided the plant realm into 24 classes according to the number and position of stamina and pistils. Although this might appear to embrace a relatively fixed arrangement of the collection, Linnaeus made it clear that this enabled him to ‘pull out and produce [any plant] without delay’. The methodical arrangement of specimens according to the sexual system served as a retrieval system for previously gathered information, and was therefore an arbitrary device that did not represent any natural order. ‘Others’, as Linnaeus therefore emphasized in the Philosophia Botanica, ‘may arrange [their herbarium] according to any other system, observing what should be observed’. The agitated background of 18th century taxonomy According to some famous remarks that Michel Foucault made in his Order of Things, 18th-century natural history was profoundly shaped by ‘herbaria, natural history cabinets, and botanical gardens.’ These institutions formed the ‘timeless rectangle’ of 18th century taxo- nomies, in which ‘beings presented themselves side by side with their visible surfaces, without any commentary and surrounding language, approaching each other by their common traits, and thus virtually analyzed, bearers of their sole names’ [20].

Indeed, Carl Linnaeus has often enough been portrayed as the prototypical protagonist of this mind-set [21].
  • 27. However, Linnaeus’ preoccupation with a taxonomy of ‘constant’ characters resulted from his engagement in a dynamic practice of transplantation and exchange, which had deep roots in the rapid and ongoing globalization of European economies [22]. Furthermore, it should not be ignored that his taxonomic works were published in several editions: Linnaeus authorized two editions of the Species Plantarum during his lifetime; the Genera Plantarum went into six; and the Systema Naturae into 12, growing from a 12-paged folio volume into three octavo volumes of approximately 1500 pages. Taxonomy had become the art of revising prior classifi- cations in the light of ‘new’ species, and Linnaeus’ herbarium cabinet was perfectly designed to accommodate this progressive movement.

  • 33. 1 2 History 281: History of Science Midterm Examination Spring 2015 Read and follow the instructions carefully. Write your answers in essay form. Draw specifically on the lectures, readings, and discussions in writing your answers. Write a brief introduction and conclusion and be sure to answer all parts of the question. Be sure to answer the question actually asked, not one you wish had been asked. Your answers will be graded on organization, clarity, specificity, and creative insight. Group I (50%) Answer one of the following questions. 1. Historians of Science have compared the role of science in the French Revolution to the mobilization of physicists during World War II to the Manhattan Project leading to the first atomic bomb. Do you think such comparison is reasonable? How did the involvement of scientists and engineers with the state during those revolutionary years contributed to mold the engineering profession in France in the following decades? 2. What material resources did Linnaeus need to undertake his studies in Botany? What do we learn from looking in detail at

Consider the following painting by F. E. Church. How is the image of nature here represented related to the figure of the romantic scientist Alexander von Humboldt? Why were people in the Americas so interested in Humboldt’s views on nature? Frederic Edwin Church, The Heart of the Andes, 1859

How can one relate the growing use of non- human animals in bacteriology with the rise of the laboratory as a crucial space for the life sciences? Can you refer to other non- human animals present in a bacteriological institute? Lisbon Bacteriology Institute, 1900 1
