24 ON THE INFLUENCE 



rabbit, therefore, in 30 minutes, gave out 25*3 

 cubic inches of carbonic acid, and consumed the 

 same quantity of oxygen gas, which is at the 

 rate of 50*6 cubic inches in an hour. 



EXPEKIMENT II. 



Thermometer 65, barometer 30-1 inch. 



A somewhat smaller rabbit was allowed to 

 remain under the bell-glass during 30 minutes. 

 The respired air contained T ^ of carbonic acid. 

 The animal occupied the space of 48 cubic inches.

The carbonic acid evolved, was therefore equal 

 to 28-22 cubic inches in half an hour, which is at 

 the rate of 5 6 -44 cubic inches in an hour. 



EXPERIMENT III. 



Thermometer 64, barometer 30*2 inch. 



A young rabbit, occupying the space of 48 

 cubic inches, was allowed to remain under the 

 bell-glass during the same period as in the two 

 former instances. The respired air contained 

 y 1 ^ of carbonic acid.

The results of this were therefore precisely the 

 same as those of the last experiment. 



These experiments were made with great care. 

 The animals did not appear to suffer any incon- 

 venience from their confinement, and their tem- 

 perature was unaltered.
