ASCENDING TRACTS IN THE SPINAL CORD 
231 
In our sections a distinct peripheral band of degenerated fibres is seen to connect this area 
with the degenerated fibres of the funiculus gracilis. We have not seen such a condition

the dorsal cerebellar tract.

In Fig. 6 the tract occupies the central part of the corpus restiforme in a position described 
by other authors, and in P'ig. 7 it is seen passing into the cerebellum. We regret that we have 
been unable to trace its further destination.

(Ill) VentraL cerebellar tract. — The position of this tract in the spinal cord is shown in 
Figs. I, 2, 3. The main portion of the fibres forms a wedge-shaped area opposite to the lateral 
part of the anterior horn, extending close up to the periphery. This peripheral situation differs 
from that given by Risien Russell,* but is in agreement with the description of other authors.
