636 FUNCTIONS OF ANIMALS. 



more than would have been produced by the quantity of oxygen 

 gas actually consumed. 



(2.) The experiment was repeated with the same rabbit. The 

 heat given out by the animal during the experiment, being 100, 

 that furnished by the oxygen gas converted into carbonic acid 

 was, . . v .-. 64.9 



By the oxygen which formed water, . 20 -9 



Total, . 85 -8 



So that 14. 2 of the heat was due to other processes. 



(3.) Six small rabbits fourteen days old were inclosed in the 

 vessel for two hours and five minutes. The air passed through 

 the vessel was 3019 cubic inches. It was reduced after the pro- 

 cess to 2971 cubic inches. So that 48 cubic inches had disap- 

 peared. The oxygen gas consumed was 254*6 cubic inches, and 

 the carbonic acid formed amounted to 180-3 cubic inches, so 

 that 74*3 cubic inches of oxygen must have gone to the forma- 

 tion of water. 



45-9 Ibs. avoirdupois of water were heated 1.796, or 1 Ib. of 

 water would have been heated 82 -43. 



But the oxygen consumed would have evolved 6 7. 9, of which 

 48 is due to the formation of carbonic acid, and 19. 9 to the 

 formation of water. The heated evolved exceeds by 14. 5, what 

 could have been produced by the formation of carbonic acid and 

 water. 



(4.) A male rabbit evolved 100 heat, of which 68.3 were 

 due to the formation of carbonic acid, and 18.4 to that of water. 

 The 13. 3 were in excess. 



(5.) Three male guinea pigs were enclosed in the apparatus 

 for one hour and fifty -four minutes. The air which passed through 

 the vessel was 2932 cubic inches, the oxygen gas consumed 

 was 201*32 cubic inches, and the carbonic acid gas formed was 

 157*93 cubic inches, so that 43*39 cubic inches of oxygen went 

 to the formation of water. 



The air by the process became 2951*8 cubic inches, or the 

 bulk increased by 19*8 cubic inches. 



By the animal heat evolved during the experiment 51*38 Ibs. 

 avoirdupois of water were heated 1M5. So that one pound 

 would have been heated 5 9. 19. 



The heat formed during the formation of the carbonic acid
