The document discusses the discovery and properties of anode rays (protons). It explains that goldstein showed the existence of protons in atoms and that anode rays are produced using a discharge tube with a perforated cathode. The anode rays travel in straight lines, can produce mechanical effects by rotating a paddle wheel, and are positively charged as they are deflected towards the negative plate in an electric field.
