OF THE BRAIN, ETC. 5 



By means of a small thermometer with an 

 exposed bulb, I measured the animal heat at 

 different periods. 



At the end of an hour the thermometer in the 

 rectum had fallen from 100 to 94. 



At the end of two hours a small opening having 

 been made in the parietes of the thorax, and the 

 bulb of the thermometer placed in contact with the 

 heart, the mercury fell to 86, and half an hour 

 afterwards in the same situation it fell to 78. 



In the beginning of the experiment I made 

 an opening into the abdomen, and having passed 

 a ligature round each ureter about two inches 

 below the kidney, brought the edges of the 

 wound in the abdomen together by means of 

 sutures. At the end of the experiment no urine 

 was collected in the ureters above the ligatures. 



On examining the blood in the different ves- 

 sels, it was found to be of a florid red colour 

 in the arteries, and of a dark colour in the veins, 

 as under ordinary circumstances. 



During the first hour and a half of the ex- 

 periment there were constant and powerful con- 

 tractions of the muscles of the trunk and ex- 

 tremities, so that the body of the animal was 

 moved in a very remarkable manner on the 

 table on which it lay, and twice there was a 

 copious evacuation of faeces.

The experiment was repeated on a rabbit. 

 The temperature of the room was 60. The re-
