 As a consequence of the treatment the arborescence is shrunken and interrupted in its 

 continuity. In Figs. 126 and 127 the end plate is considerably larger than in 128 and 

 129. In Fig. 126 it is in connection with two nerve-branches. Fig. 130 shows a 

 section through an end-plate. The latter is bounded externally by a sharply defined 

 line, which can be traced along the surface of the muscle-fiber. This is to be regarded 

 as the sarcolemma.
