the body when immersed in cold water, the fol- 

 lowing experiments were performed. 



EXPERIMENT I. 



A fine adult rabbit, of the temperature of 104, was im- 

 mersed, with the exception of the head, in water of 50i. 

 In two or three minutes, the animal began to shiver ; in 

 five it was removed ; and its temperature was found to be 

 94. It was directly immersed in warm water of 106 for 

 the same space of time, during which it gained 4 degrees, 

 its temperature being 98. 



EXPERIMENT II. 



An adult rabbit, temperature 106, but not so robust as 

 the preceding, was immersed in water of 50 for five mi- 

 nutes, during which time its temperature was reduced to 

 96i: It was immediately placed in warm water of 110 for 

 the same time, at the end of which its heat had risen to 

 98^. We did not think it necessary to keep the rabbits 

 a longer time in the water. They both seemed much op- 

 pressed : and when we consider that one, in the short space 

 of five minutes, lost 10, and the other about 8, we have 

 changes sufficiently great to account for such symptoms. 



CCI. Without the corroboration of the preceding 

 experiments, the description which CRAWFORD 

 himself gives of the appearance of one animal 

 subjected to a cold medium, and of another to a 

 warm one, is sufficient to prove the consistency 

 of the present opinion. The one exposed to cold
