At the end of two hours it had fallen to 70, and at the end 
of two hours and a half to 3,5 in a minute, and the artificial 
respiration was no longer continued. 
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 ioo° to 94 0 . 
At the end of two hours a small opening being made in the 
parietes of the thorax, and the ball 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 artery 
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 vessels, it was 
found 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 experiment there 
were constant and powerful contractions of the muscles of the 
trunk and extremities, 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. 
Experiment 3. 
-•The experiment was repeated on a rabbit. The temperature 
of the room was 6o°. The respirations were made from 30 
to 35 in a minute. The actions of the heart at first were
