nerve-fiber becomes continuous with the sarcolemma of the muscle- 

 fiber at the place where the neuraxis passes under the sarcolemma. 

 Henle's sheath continues over the motor ending as a thin sheath, 

 containing here and there flattened nuclei, the telolemma nuclei. 



With the majority of the reagents used to bring to view the

the telodendrion of the nerve-fiber is found, has a granular appear- 

 ance, and is consequently differentiated from the remaining sarco- 

 plasm of the muscle-fiber. To this the term granular sole plate has 

 been applied, the nuclei contained therein being known as sole nuclei, 

 the whole ending as the motor end-plate. If the above interprets,-
