 as not to be distinguished to beat 

 tlrrough the integuments. 

 11. — It was put into the cold again.

 the belly and the thigh was be- 

 ginning to freeze, and it had no 

 power of motion. The thorax 

 was opened, the heart presented 

 itself, beating feebly only six 

 times in a minute; after being 

 exposed to the air for a few 

 \ minutes, the animal recovered a 



slight degree of motion, and the 

 heart encreased to eighteen pulsa- 

 tions in a minute. The animal 

 was dead about an hour after. 

 From these experiments, I am enabled to 

 draw the following conclusions. 



1st. That cold diminishes the actions of the 

 body. 



2d. That this effect is shewn by the di- 

 minished temperature and diminished action of 

 the heart. 



It is deserving to be remarked, that when 

 the rabbit was put into the cold, its pulse was 

 accelerated, but rendered more feeble; buc
