ON THE INFLUENCE 



I killed one of them by dividing the spinal chord, 

 and immediately, having made an opening into 

 the left side of the thorax, I tied a ligature 

 round the base of the heart, so as to stop the 

 circulation. The external wound was closed by 

 a suture. An opening was then made into the 

 trachea, and the apparatus for artificial respira- 

 tion having been fitted into it, the lungs were 

 inflated, and then allowed to collapse as in the 

 former experiment, about 36 times in a minute. 

 This was continued for an hour and a half, and 

 the temperature was examined at different pe- 

 riods. The temperature of the room being the 

 same, I killed the second rabbit in the same 

 manner, and measured its temperature at cor- 

 responding periods. The comparative tempe- 

 rature of the two dead animals, under these 

 circumstances, will be seen in the following table. 



In this last experiment, as may be seen from 

 the above table, the difference in the temperature 

 of the two rabbits, at the end of an hour and a
