Cuap. IV. THE EFFECTS OF HEAT. 75 
water does not cause any inflection: I suddenly placed 
four leaves, taken from plants which had been kept for 
several days at a high temperature, generally about 
75° Fahr. (23°8 Cent.), in water at 45° (7°-2 Cent.), but 
they were hardly at all affected; not so much as some 
other leaves from the same plants, which were at the 
same time immersed in water at 75°; for these became 
in a slight degree inflected.
