This document discusses different types of goods under the Sale of Goods Act, including existing goods, future goods, and contingent goods. It then focuses on perishable goods and the effects of perishable goods perishing on contracts for sale. It explains that if the whole of the specific goods perish before a contract is made, the contract is void. If only part perishes, the contract may be void if entire or remain valid if divisible. If goods perish after an agreement to sell but before risk passes, the agreement is void.
