 traced with fine scissors, forceps and tracer. The animal was transected ( 234) and the 

 cephalic half preserved in alcohol ( 286).

 branch of the ulnar nerve ( 1029). Trachea The windpipe ( 799). 



Preparation of Fig. 106. This is the same as for Fig. 105, except that all of the soft 

 parts were removed so as to show the exit of the nerves from the intervertebral foramina.
