The Journal of nervous and mental disease. ference between the two pyramidsis still less marked in sections stained with carmine or with the mix-ture of picric acid and fuchsin; a keen-eyed pathologist, to whomsuch a section was submitted, declared himself at first unable to dis-cern the difference, although he had found the evidence of the Wei-gert stain clear enough. Yet there is an extremely slight increase inthe neuroglia in the right pyramid. Most of the cervical cord waseither not obtained or was greatly damaged. Sections from its lower LESION IN THE PUTAMEN i part and from the upper part of the dorsal cord show in the area ofthe right uncrossed pyramidal tract a loss of myelin and what ap-pears on close comparison with the tissue on the other side to be anextremely slight increase of glia, not detectable otherwise; while inthe postero-lateral column on the left the pyramidal area is not atall distinguishable in Weigert sections, but here again comparisonwith the other side seems to disclose an increase in the Fig. ii. The paler pyramid is the right. Below the upper dorsal region no pyramidal affection could be madeout. The manner in which the brain was prepared not having beenfavorable to the study of cell changes, it only remains to say thatsuch specimens as were obtained indicated that the cells of the pu-tamen could hardly have survived in considerable number, or pre-served their function, where the glial proliferation was process which originated in the. putamen and lead to the changesshown in the illustrations does not seem to have encroached uponthe globus pallidus to any marked extent, the loss of myelinatedfibers in the latter appearing to be secondary to the affection of theputamen. Accordingly, nerve cells are observed to l>e present in theglobus; whether they have undergone considerable diminution in tia L. XHUM.
