ON THE MANIFESTATION OF ELECTRIC FORCE, OF 

 CHEMICAL FORCE, AND OF HEAT, DURING MUSCULAR 

 CONTRACTION. 



Sect. I. On the Manifestation of Electric Force during 

 Muscular Contraction. 



I shall purposely abstain from entering upon the 

 personal disputes that have arisen during the dis- 

 cussion of some of the questions that will now 

 occupy our attention, and only refer in a general 

 note to the principal sources from whence I have 

 been enabled to obtain such views as are confirmed 

 by experimental evidence, and which are now 

 entertained upon the subject of our present inquiry'.
