174 JouRNAL OF COMPARATIVE NEUROLOGY. 
Fig. 39. Neurone from the right pallial eminence. Its axone finally enters 
the tractus pallii. The Goict method, X 230. 
Fig. go. Neurone from the right pallial eminence sending its axone into 
the pallial commissure. The GOLGI method, X 230. 
Fig. gt. A neurone of CAJAL from the left pallial eminence. The GOLGI 
method, X 230. 
fig. ga. Ependyma from the left striatum. The fibres really extend en- 
tirely to the limitans externa, but only the inner portion has been represented. 
The Gouc! method, x 230. 
Fig. 43. Neurogliar element from the pallial eminence. The GOLGI 
method, X 230. 
PLATE XI. 
Fig. 4g. A tract-neurone lying just to the left of the median raphe of the 
oblongata, sending its axone into a tract of the opposite side. The NIssL 
method, xX 900. 
Fig. 45. Commissural neurone from the right side of the oblongata; its 
axone passes to the left across the median raphe. The NissL method, X 1120. 
fig. 46. Neurone from the right lobus vagi. The Niss_t method, X 1120. 
Fig. 47. Neurone from the right viscero-motor nucleus of the oblongata. 
The axone passes dorsal to the fasciculus communis on its way to the fasciculus 
longitudinalis dorsalis. The NissL method, x goo. 
Fig. 48. Oblongata. Two of the deeper neurones from the right general 
cutaneous nucleus just dorsal to the lobus vagi; they lie between the bundles 
of the spinal V tract, indicated in outline. The Nisst method, x 1120. 
PLATE XII. 
Fig. g9. Two PURKINJE neurones from the cerebellum. The Nissi meth- 
od, X 1120. 
fag. 50. Two neurones from the molecular layer of the cerebellum. These _ 
lie unusually close together. The Nissi method, x 1120. 
fig. 51. Five neurones from the granular layer of the cerebellum. A 
nerve-fibre is seen ascending between them to the molecular layer. The Nissi. 
method, 1120. 
Fig. 52. WNeurones of the superficial and middle layers of the tectum 
mesencephali. The Nissi method, X goo. 
fig. 53. A group of the spindle-shaped neurones :characteristic of the 
deeper layer of the tectum mesencephali. The Nisst method, X goo. 
Fig. 54. A group of the stellate neurones found at intervals in the deeper 
layer of the tectum mesencephali. The Nissi method, x 900. 
fig. 55. The region immediately dorsal to the aqueduct of SyLvius, show- 
ing the disposition of the neurones of the roof-nucleus. Methylen-blue, x 89. 
Fig. 56. Neurone from the left half of the midbrain roof-nucleus. The 
NIssL method, x goo. -
