Exp. 6. Thermometer 66°, barometer 30.1 inches. 
Two rabbits, each occupying the space of 48 cubic inches, 
were inoculated with woorara. 
In one of them, when apparently dead, the circulation was 
kept up by means of artificial respiration. He was placed in 
the apparatus under the bell-glass, and the lungs were inflated 
from 50 to 60 times in a minute. At this time the thermo- 
meter in the rectum stood at 07°. At the end of 35 minutes, 
a portion of air was preserved for examination. The ther- 
mometer had now fallen to go 0 . The heart was still acting 
regularly. 
The second rabbit was allowed to lie dead. When the 
thermometer in the rectum had fallen to 97°, he was placed 
under another bell-glass. At the end of 35 minutes, the 
thermometer had fallen to 90°. 5. 
The air respired by the first rabbit contained of carbonic 
acid. 
5 -° 2 - 2 ^--- ~ — — ~ = 31.75 cubic inches of carbonic acid 
evolved in 35 minutes, which is at the rate of 54.43 cubic inches 
in an hour. 
Exp. 7. Thermometer 6o°, barometer 30.2 inches. 
The experiment was repeated on a rabbit, which had been 
inoculated with the essential oil of almonds. When he was 
placed under the bell-glass, the thermometer in the rectum 
stood at 96°. In a few minutes he gave signs of sensibility, 
and made efforts to breathe ; but as these efforts were at long 
intervals, the artificial respiration was continued. In half an 
hour he breathed spontaneously 40 times in a minute. The 
thermometer in the rectum had fallen to go 0 *
