of emergence of the vomeronasal bundle from its foramen. This 

 strand assmnes an independent course, running dorsally a little 

 way, then divides into a nmnber of smaller strands whose gen- 

 eral course is rostrally. These become so attenuated by re- 

 peated division that it was not possible to follow their finer 

 ramifications by dissection. Apparently they form a portion of 

 a plexus similar to that found in the cat and in other mammals.

 of a puppy two weeks old (estimated) showing nervus terminalis. 



The course of the nerve strands in the septum was followed to 

 some extent by the expedient of stripping off the thick mucosa 

 from the bony septum and examining its deeper surface. This 

 required a minunum of dissection, as the nerve strands lay for 

 the most part in the deeper portion of the mucosa. The proxi- 

 mal portions of the first two divisions of the vomeronasal nerve 

 lay in rather deep furrows in the bony septmii, and the strands 

 of the terminalis which accompany the larger nerve through the 

 cribrifonn plate, accordingly, emerge from the sheath very close 

 to the periosteum of the bony septmn. In addition to the rami
