8 ON THE INFLUENCE 



The bulb of the thermometer having been placed 

 within the pericardium, the mercury stood at 85, 

 but when among the viscera of the abdomen it 

 rose to 87^. 



During the experiment there were frequent 

 and violent contractions of the voluntary muscles, 

 and an hour after the experiment was begun, 

 there was an evacuation of faeces. 



EXPERIMENT V. 



The experiment was repeated on a rabbit, 

 whose respirations, as far as I could judge, were 

 from 30 to 40 in a minute, and whose pulse 

 varied from 130 to 140 in a minute. The tem- 

 perature of the room was 57. The heat in the 

 rectum, at the commencement of the experiment, 

 was 101 J. The artificial respirations were made 

 to resemble the natural respirations as much as 

 possible, both in fulness and frequency. 



At 15 minutes from the time of the spinal 

 chord being divided, the heat in the rectum had 

 fallen to 98^. 



At the end of half an hour the heart was felt 

 through the ribs, acting strongly 140 times in a 

 minute. 



At 45 minutes the pulse was still 140 ; the 

 heat in the rectum was 94. 



At the end of an hour the pulse continued 

 140 in a minute ; the heat in the rectum was 

 92 ; among the viscera of the abdomen 94 ; 

 in the thorax, between the lungs and pericar- 

 dium, 92.
