12:20 P. M. — Sensation seemingly perfect; the dog can kick well with all his legs, but cannot get 

 up on them. Rectal temperature 100°. 48. Dog killed. 



Autopsy. — Complete destruction of the left cerebellar lobe and peduncle ; upper .superficial 

 portion of the pons completely destroyed. , 



Heat Dissipation. 



First Period — 

 Quantity of air (V) = 82.47 at 70O.60 — 32^ = .38.69 = t'. 



Y 4. (V X t' X 0.002035) = V. V = ?^ = 76.4. W = V X 0.08073 = 6.17. 

 Rise in temp, of air 2.02 = t. Q = W X t X sp. h. = 6.1 7 X 2.02 X 0.2374 = 2.9588 = heat given to air. 

 Rise iu temp, of water 0.288 X 164.1414 = 47.2727 = heat given to calorimeter. 



2.9588 = heat given to air.
