Drs. Gall and Spurzheim on the Structure of the Brain

medullary fibres may be easily traced to the cerebellum. This, indeed, was known to the older anatomists, who called it " processus cerebelli ad medullam oblongatam." In its course upwards, it meets with a mass or ganglion called corpus dentatum, which contains much brown matter, and is considered by Dr. S. a preparatory apparatus, destined to increase the medullary filaments which enter it. From this the primary fasciculus receives, as usual, accessions of white nervous bundles, and, thus strengthened, divides into many medullary branches and layers, which form the hemispheres of tjie cerebellum. One of these branches or layers goes to form the proces-
