A STUDY IN M01I151D AND NORMAL JMIVSIOLUUY. 71 



January 4. 



1:"0 r, M. — Dog is conscious, witli dulled but not destroyed sensiliility in the l)ody, and cxces.sive 

 hypera3stliesia of the head and upper neck, howling violently wlien tliese jiarl.s arc touched, lie can 

 kick with all of his legs, but i.s unable to move his body. lie was placed on the table, the tlier- 

 moincter introduced through an oi)cning in the linea allia into the peritoneal cavity, and the .sciatic 

 exposed. The galvanic current enij)loycd was the full power of a Du Dois Iteynioud coil, with one 

 large LeClanche cell. 



Autopsy.— Section traversing entirely the medulla from side to side on its up])er surface on a line 

 with its junction with the [ions, reaching half-way through, but leaving the lower part intact. 



Heat Dissipation. 

 Before Section. 



Quantity of air (V) = 68.71 at 640.47—32° = 32.47 = t'. 



V + (V X t' X 0.002035) = v. A' = ''-^•-- = 64.4. W = V x 0.08073 = 5.2 



1.066 



Rise in temp, of air 2.3 -= t. Q = W x t X sp. h. = 5.2 x 2.3 x 0.2374 = 2.8393 = heat units given to air 

 Rise in temp, of water 0.234 X 164.1414 = 38.4091 = heat given to calorimeter. 



2.8393 = heat given to air. 



Total dissipation of heat in an hour 41.2484
