Fig. 4. Twoneurones from the lobus vagi of the oblongata, and a com- 
munis fibre (c. f.) having its terminal arborization near a cell not drawn. The 
axones are directed into the deeper nervous matter. The GOLGI method, x 230. 
fig. 5. Oblongata; a small area from the substantia gelatinosa of the 
general cutaneous nucleus. The minute neurone (a) has a profusely branching 
axone, with which the dendrites of (4) interlace to form atcomplex tangle; in this, 
the general cutaneous fibre (g. c. f.) has its termination. The axones of (6) and 
(c) penetrate the deeper levels of the nucleus. The GoLGi method, x 230. 
fig. 6. Oblongata; a neurone from the deeper part of the left general 
cutaneous nucleus. A generai cutaneous fibre (g. c. f.) is seen breaking up into 
a terminal arborization. The GOLGI method, x 230. 
Fig. 7. Oblongata. Two PURKINJE neurones from the cerebellar crest of 
the tuberculum acusticum. An acustico-lateral fibre (a. 7. 7.) is seen terminat- 
ing near the one on the right. The GoLGi method, X 230. 
fig. 8. Oblongata; ependymal fibres from the outer level of the general 
cutaneous nucleus. The GOLGI method, « 230.” 
Fag. 9. Ependymal fibres from the ventral oblongata, forming a bundle in 
the formatio reticularis. The GoLcGi method, X 230. 
Fig. ro. Ependyma from the lobus vagi of the oblongata. The GOLGI 
method, * 230. 
fig. rr. Neuroglia cell from the general cutaneous nucleus of the oblon- 
gata. The GOLGI method, x 230.

fig. 12. Sagittal section through the entire cerebellum showing its folds, 
the form of its ventricle, its neurone-layers, and its principal masses of nerve- 
fibres. The WoLTERS method. Outline x 8. 
Fig. 13. Neurone of PURKINJE from the cerebellum. The GOLGI method, 
x 230. 
fig. 1g. Neurone from the molecular layer of the cerebellum. The great- 
est extension of the dendrites is parallel with the surface of the cerebellar fold. 
The GOLGI method, x 230. 
Fig. 75. Three representative neurones from the granular layer of the 
cerebellum. The intervening cell-bodies are omitted for the sake of clearness. 
The axones are cut across at the juncture of the granular with the molecular 
layer; see Fig. 16, and the description in the text. The GOLGI method, X 230. 
fig. 16. Axones in the molecular layer of the cerebellum passing trans- 
versely across the organ, derived from the neurones of the granular layers. 
Several ascending axones are to be seen just previous to their T-shaped divis- 
ion. The Gorci method, x 230. 
Fig. 17. Neurone of the Goxrer II type from the granular layer of the 
cerebellum. The Gouci method, x 230. 
Fig. 19 Neurogliar cells from the cerebellum. The cell-bodies lie between 
the neurones of PURKINJE. An astrocyte is seen at (ast¢.); and a BERGMANN’S 
fibre at (6g. f.). The GoLct method, x 230. : 
Fig. 20. ‘Transverse section of the midbrain. The WOLTERS method, x 14. 
fig. 27. Transverse section of the entire thickness of the left optic lobe, 
showing the neurones of the tectum mesencephali. The GoLGi method, x 46.
