the left muscle fibi-e. At a, we have an intact sympatlietic nerve 

 that ends with a loop in a degenerated motor plate. At a the prepa- 

 ration has an intact sympathetic nerve that passes away along the 

 left muscle fibre forming loops and varicosities. This nerve fibre 

 has no terminal loops in this preparation, but at one place half 

 way between a and d a part of the extension of the nerve fibie is 

 connected with a peiiterminal network and seems on this account 

 to be situated hypolemmally. 



The preparation that fortns the basis of fig. 2 shows, among other 

 things, a muscle fibre with two degenei-ated motor terminal |»lates. 

 These terminal plates are clearly situated on the same muscle fibre 

 and are at such a distance from each other as one generally sees 

 in plurisegmental spinal innervation of separate cross-striated muscle 

 fibres. All intact sympathetic nerve [a) with a simi)le loop formation 

 terminates within the region of the motor plate {d). There are thus 

 instances of sympathetic nerve fibres in the musculature of the 

 extremity as well, that terminate within the region of a motor plate.
