    exhibited no cork-screw appearances; but it was possible that their ulti- mate termination, as well as the terminations of the Betz cells in the tangential layer were damaged or destroyed; otherwise the outline of the cells corresponded with the outlines of normal cells. By Nissl stain- ing the cells showed large clear nuclei and a marked deficiency of chro- mophyllous substance. The tigroid substance was almost absent in the body of the cells and on the dendrons in sections of the left ascending frontal. A similar appearance was observed in the right ascending frontal, but it was not nearly so intense; there was more chromophyllons Photomicrograph of cortex of left facio-lingual area stained by Cajal fibril method ; it shows remarkably well the neuroglia cell hyperplasia and their extensions on to the walls of the small vessels.

By the silver method, fibrils could be seen running through the cells, and there was apparently not very much change. The sections of the cortex at the end of the left Sylvian fissure exhi- bited very similar changes, but owing to the adhesion of the pia arach- noid to the dura, the cortex presented an eroded appearance; apparently the inflammatory process in this lesion started in the pia arachnoid in- stead of within the dura; it was more recent in origin and less extensive. There was a marked glia proliferation, and the same changes in the layers of cells noted in the other lesion. Medulla oblongata.—Examination of the medulla oblongata showed a 2-4 e 2
