The second rabbit died in a few minutes after the inocula- 

 tion. The time was rioted 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 Q2°.

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 97 '. At the end of 35 minutes, 

 a portion of air was preserved for examination. The ther* 

 mometer had now fallen to 9O . The heart was still acting 

 regularly. 



The second rabbit was allowed to lie dead. When the ther- 

 mometer in the rectum had fallen to 97% he was placed under 

 another bell-glass. At the end of 35 minutes, the thermo- 

 meter had fallen to 90°'5.
