After Section. 



Quantity of air (V) = 79.434 at 730.98- 32° = 41.98 = t'. V + ( V x I' X 0.(JU-J035) = V. 



V = — ^- = 73.2. W = V X 0.08073 = 5.91 

 1.085 



Rise in temp, of air 3.G1 = t. Q = W x t x sp. h. = 5.91 x 3.61 x 0.2374 = .VOCO = heat given to air. 



Kise in temp, of water 0.63 X 164.1414 = 103.4091 = heat given to calorimeter. 



5.065 ^ heat given to air. 



Hourly dissipation of heat 108.4741 



Summary. 



Hourly (lis.?ipation of heat after section 108.4741 

 Hourly dLssipation of heat before section 44.6922 



Gain in hourly dissipation of heat folio-wing flection 63.7819 



Heat Prodndloii. 

 Before Section. 



No change in bodily temperature. 



Hourly heat dissipation = hourly heat production 44.6922. 



After Section. 



Fall in temperature of animal in 85 minutes 80.72. 



Fall in temp, per hour 6.156 = t. AV = 26.25. 



Q = W X t X sp. li. = 26.25 X 6.156 x 0.75 = 121.1963* = heat drawn from reserve. 



Heat drawn from reserve 121.1963 

 Heat dissipated hourly 108.4741 



Heat lost from reserve over and above that accounted for 12.7222 



Summary. 



Heat production before section 44.6922 



Heat lost from reserve after section above that accounted for 12.7222 



Difference in heat production before and after section 57.4144 



Experiment 55. 



A terrier bitch. Weight 16.2.5 pounds. 



2 p. M. — Section made. The trephine slipped and wounded the nerve centres. 2:3 p. m. — Rectal 

 temperature, 104°; 2:10 p.m., rectal temperature, 102°. 92; 2:20 p.m., rectal temperature, 102°. 92. 



* This is probably excessive, because the cooling of the animal was almost certainly more rapid 

 directly after the temperature in the rectum was taken than it was later.
