directed caudad (fig. 33). Many Golgi preparations show that 
the region reached by these axons is also reached by fibers passing 
between the wall of the infundibulum and the pars nervosa of 
the hypophysis, including the saccus vasculosus; but actual 
continuity of these neurons with the hypophyseal fibers has not 
been observed. This, however, has been demonstrated by

Bochenek (’02) in Salamandra. A similar tract to the saccus 
vasculosus has been described by others (e.g., Johnston in Acipen- 
ser, 01, p. 67), and Cajal (711, p. 489) describes in the mouse 
what is probably the same connection, the fibers arising from 
a cluster of neurons immediately behind the optic chiasma.
