ON THE INFLUENCE 



the second rabbit was killed by dividing the 

 spinal chord, and the temperature was ex- 

 amined at corresponding periods. 



Half an hour after the rabbit was killed, the 

 heat in the rectum was 99. 



At 45 minutes it had fallen to 98. 



At the end of an hour the heat in the rectum 

 was 96^. 



At an hour and a quarter it was 95. 



At an hour and a half it was 94. 



At an hour and 40 minutes the heat in the 

 rectum was 93, and within the pericardium it 

 was 90. 



The following table will shew the comparative 

 temperature of the two animals at corresponding 

 periods. 



In this experiment, the thorax, even in the 

 dead animal, cooled more rapidly than the abdo- 

 men. This is to be explained by the difference 

 in the bulk of these two parts. The rabbit in
