gS 6 Mr. Brodie’s Experiments and Observations 
merits I employed animals, which had been inoculated with 
the poison of woorara, or the essential oil of almonds; by 
which means, while the functions of the brain were completely 
destroyed, the extent of the circulation was undiminished, and 
all chance of accidental haemorrhage was avoided. 
Exp. ,5. Thermometer 6g°, barometer 29.8 inches. 
Two rabbits were procured, each occupying the space of 45 
cubic inches. They were both inoculated with the woorara 
poison. 
The first rabbit was apparently dead in nine minutes after 
the application of the poison ; but the heart continued to act. 
The lungs were inflated for about two minutes, by means 
of a pair of bellows, when the thermometer in the rec- 
tum was observed to stand at 98°. The animal was placed 
under the bell-glass, and artificial respiration was produced 
by means of pressure on the gum-bottle, as in the last ex- 
periment. At the end of 30 minutes, a portion of air was 
preserved for examination. The thermometer in the rectum 
had fallen to 91 0 . The heart still acted with regularity and 
strength. 
The second rabbit died in a few minutes after the inocula- 
tion. The time was noted when the thermometer in the rec- 
tum had fallen to 98°, and he was placed under a bell-glass. 
At the end of 30 minutes, the thermometer in the rectum had 
fallen to 92 0 . 
The air respired by the first rabbit contained ^ of carbonic 
acid. 
502 + 52 + 2-45 _ 5_^ __ cubic inches of carbonic acid 
evolved in 30 minutes, which is at the rate of 51.1 cubic inches 
in an hour.
