 3:5 p. M. 90-100 



3:10 115-120 Galvanic current has l)cen applied to the sciatic for half a niiniite. some not violent 



reflex contractions, much disturbance of respiration. 



3:16 Par vafjum cut. 



3:21 65-95 Much disturbance of respiration. 



3:24 Mild galvanic current applied to the sciatic. 



3:26 120-125 Pressure has been steadily rising since the current was applied : there have been no 



general convulsive movements, but breathing has apparently been affected. 

 3:35 Animal killed. 



Autopsy. — Right half of medulla completely separated exactly at its jiinctidn with the pons, 

 excepting a small band upon each side. Left half severed, except a film all ucrosd at the lower 

 surface, and a band at the outer edge. No cerebral hemorrhage. 



Heat Dissipatio7i. 

 Before Section. 



Quantity of air (V) = 80.87 at OS^.SO— 32- = 33.50 = t'. 



V + (V X t' X 0.002035) = V'. V = -^'':?1 = 81.3. W = V x 0.08073 = C.56 



Rise in temp, of air 6.34 = t. Q = W x t x f p. h. = 0.5G X 6.34 x 0.2374 = 9.8735 = heat given to air. 

 Else in temp, of water 0.708 X 104.1414 = 110.2121 = heat given to calorimeter. 



9.8735 = heat given to air.
