Pi?.?. Composite transversa Eection of tbe oblongata at 

 the level of the IX nerve. The Golgi Tethod. Outline * 14. 



Pi?.?. Structural elements froiri the formatio reticularis 

 on the ri?ht side of the oblongata. The commissural neurone 

 (c.n.) sends its axone across the iredian raphe. Tbe upper 

 neurogliar cell (ng.) has its longer axis extended in the radius 

 of the oblongata. The Golgi nretbod, * 230. 



Pig. 4. Two neurones frcm the lobus vagi of the oblongata, 

 and a communis fibre (c.f.) having its terminal arborization 

 near a cell not drawn. The axones are directed into tbe deeper 

 nervous matter. The Golgi method, x230. 



Pig. 5. Oblongata; a small area from the substantia gelat- 

 inosa of the general cutaneous nucleus. The minute neurone (a) 

 has a profusely branching axcne, w i t ti which the dendrites of (b) 

 interlace to form a socplex tangle; in this, the genei-al cuta- 

 neous fi>ire (g.c.f.) has its termination. The axones of (b) and 

 (o) penetrate the deeper levels of the nucleus. The Golgi 

 method, x 230. 



Pig. 6. Oblongata; a neurone from the deeper part of the 

 left general cutaneous nucleus. A general cutaneous fibre 

 (g.c.f.) is seen breaking up into a terminal arborization. 

 Tbe Golgi method, x 230. 



Pig. 7. Oblongata. Two Purkinje neurones from the cere- 

 bellar crest of the tuberculum acusticum. An acustico-lateral 

 fibre (a.l.f.) is seen terminating near the one on the right. 

 The Golgi method, " 230. 



Pig. 8. Oblongata; ependymal fibres from the outer level 

 of tbe general cutaneous nucleus. The Golgi method, " 250. 



Pig. 9. Bpendymal fibres from the ventral oblongata, 

 forniing a bundle ic the formatio reticularis. The Golgi ffethcd, 

 X 230.
