(Abstract.) 



The apparatus employed in the present investigations was the same 

 thermo-electric one that was used in the experiments on conduction of 

 heat in bone, brain- tissue, and skin, described in a former paper,* but 

 the mode of application of the thermo-pile to the tissue was somewhat 

 different. The tissue, whether hard or soft, was placed on a thin 

 copper plate, which formed the floor of a square hole cut in the bottom 

 of a small light wooden box. The pile, having been applied to the 

 upper surface of the tissue, was held in place by means of a paste- 

 board collar, which was made fast with pins to the edges of the box. 

 In the case of the soft tissues, light weights were affixed to the pile to 

 regulate the pressure. With bone, in order to insure intimate contact 

 between the pile and the tissue, and between the latter and the copper 

 plate, a little marrow was used. The unoccupied space in the box 

 was filled with finely chopped cotton-wool. The box had pasteboard 

 uprights attached to its sides, by which it was suspended from the
