LECTURE H. 



I proceed to speak of the structure 

 and functions of the nervous fibres. 



The nerves which we observe per- 

 vading the body, appear to be packets 

 of very minute threads, seemingly distinct 

 from each other. The nerves divide and 

 subdivide, and in so doing a certain 

 number of threads separate from the ori- 

 ginal packet, an f d appear as a distinct 

 nerve. It is, therefore, possible to trace 

 a minute nerve, up to its origin, from 

 the toe or finger, by splitting it off from 

 the various packets with which it has 

 been conjoined. So far does anatomical 

 fact concur with the physiological opinion,
