INFLUENCE OF THE BHAIN ON THE ACTION OF THE HEART; 363- 



ment was 99^, The artificial inspirations were made to 

 correspond as nearly as possible to the natural inspiralions 

 both in fulness and frequency. 



At 20 minutes from the time of the dog being pithed, 

 the heart acted 140 times in a minute with as much strength v, 

 and regularity as before : the heat in the rectum had fallen 

 to m\. 



At 40 minutes the pulse was still 140 in a minute : the 

 heat in the rectum 921. 



At 55 minutes the pulse was 112, and the heat in the 

 rectum 90*. 



At one hour and 10 minutes the pulse beat ninety in « 

 minute, and the heat in the rectum was 88°. 



At one hour and 25 minutes the pulse had sunk to 30, 

 An4 the heat in the rectum was 85*=*. The bulb of the 

 thermometer being placed in the bag of the pericardium, 

 the mercury stood at 85®, but 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. 



Exp. 5. The experiment was repeated on a rabbit, whose Exp. 5. On a 

 respirations, as far as I could judge, were from 30 to 40 '^*^^^'' 

 jn a minute, and whose pulse varied from 130 to 140 in a 

 minute. The temperature of the room was 57^. The 

 heat in the rectum, at the commencement of the experi- 

 jnent, was 101 J. The artificial respirations were made to 

 T€8emble the natural respirations as much as possible, both 

 in fulness and frequency. 



At 15 minutes from the time of the spinal marrow being 

 iiivid(td, 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 mi. 

 tiute; the heat in the rectum was 92®; among the viscera 

 of the abdomen 94"* ; in the thorax, between the lungs and 

 pericardium, 92®.
