After Irritation. 

 Qiiautity of air ( V) = 135 at 7P.82 — 32'' = 42.82 = t'. 

 V + {V X t' X 0-00203.-,)= v. V = J^.- = 124.2. W = V x 0.08073 = 10.03 



Fall in temp, of air O.G = t. Q = W X t x sp. h. = 10.03 x O.G X 0.2374 = 1.4287 = heat f^kon from air. 

 Eise in temp, of water 1.215 X 130.8589 = 158.9936 = heat given to calorimeter. 



1.4287 = heat talieii from air. 



157.5049 = heat di.ssipatcd in U hours. 

 Hourly di--isipa(ion of heat 105.0433 

 Summary. 



Heat dissipated before irritation 140.5545 



Heat dissipated after irritation 105.0433 



Hourly loss of heat dissipation fuUowing irritation 35.5112 



Heat Production,. 

 Before Irritation. 



No change of bodily temperature. 



Heat dissipated in an liour = hourly production nf heat 140.5545 



After Irritation. 



Rise of bodily temperature in 2 hours .2, in I hour 0.1 = t. 



Q = W X t X sp. h. = 22 X 0.1 X 0.75 = 1.G5 = heat added iu an hour to reserve. 



105.0433 = heat dissipated in an hour. 



Hourly production of heat 10G.G933 

 Summary. 



Hourly heat production licforc irritation 140.5545 

 Hourly heat production after irritation 10G.(i'.)33 



Hourly diminution of heal production following irritation 33.S612
