60 GRAY SUBSTANCE or THE TRAPEZIUM, 



nally. Very numerous bundles proceed from the inner edge of the nucleus, cross- 

 ing the roots of the abducens, and decussating at the raphe with similar bundles 

 from the opposite side, serving to bring the two opposite nuclei into very close 

 connection. The cells of the anterior portion of the nucleus are more nearly stellate 

 in form, and send out their processes either in the direction of the facial roots, or 

 towards the raphe, or as is very often the case into the antero-lateral network, Avhere 

 they are brought into connection with the upper olivary bodies by little scattered 

 cell-groups and fibres, just as the hypoglossal nuclei were joined to the lower 

 olivaries (Fig. 10")- In the cat the cells are fewer in number, and more scattered 

 through the antero-lateral network, but are often large, measuring sometimes as 

 much as ^ i^ of an inch in diameter. The connection between the upper olivary 

 bodies and the nucleus of the facial, will be described in a subsequent chapter 

 (Chap. V).
