PLATE 2. 



Fig. 3. A, B, C, Transverse sections cf oculomotor nerve of fowl at different 

 points along its course, nerve tracts and cells diagrammatic (A, most 

 proximal ; C, most distal). I), Transverse section of oculomotor ciliary 

 nerve. Shaded areas indicate regions of small neuraxons ; unshaded 

 areas, regions in which hirge neuraxons predominate. X 33.

 cells of transitory ganglion of ophthalmic branch of trigeminal nerve. 

 y, Ganglion cell of mesocepbalic ganglion, cl. comit., " Accompanying" 

 cell of ophthalmic branch of trigeminal nerve. Fixed in Zenker's fluid 

 and stained with iron haematoxylin. X 933.

 from proximal end of ophthalmic branch of trigeminal nerve. Fixed and 

 stained in vom Rath's fluid. X 600. 



Fig. 7. Portion of a section from an embryo in Stage V (118 hrs. incubation), 

 showing neuraxons and fibrils from different points along course of the 

 oculomotor nerve. A, proximal; B, intermediate; C, distal. Fixed
