Journal of the Medical Society of New Jersey . oid glia cells with more or less fat,while in far advanced ones there was noevidence of an active degenerating process,the columns being composed of a densemass of glia cells and fibres with an occa-sional swollen and tortuous axiscylindernerve fibre. The penetrating twigs of the spinal ves-sels and the ascending and descendingbranches of the sulco-marginal vessels con-tain a varying amount of lymphocyteand plasma cell infiltration. This infiltra-tion was extensive in most of the recentcases, but was very light in the far ad-vanced ones : however, there were plasmacells present in every case. The plasmacell infiltration in the cord substance cor-responded in intensity to the infiltration inthe pia. These plasma cells were present throughthe entire length of the cord, medulla andlower part of the pons, where they seemedto terminate. It was very exceptional tofind plasma cells beyond this structure. Inthe few mid-brains which were examinedplasma cells were the exception and not Oct., 1914 JOURNAL OF THE MEDICAL SOCIETY OF JN EW JERSEY. 50/ The same condition existed in the cere-bral cortex as in the mid-brain. It was uticommon to find a plasma cell or infiltrationof any kind. The intima of the vessels, in the tissue ofthe cord as well as in the pia, was generallythickened to a greater or lesser extent, butthere were a few instances where the thick-ening was very slight or entirely absent;again, others were thickened to such anextent that the lumina were practically ob-literated. This endarteritis, being rare inthe brain, was more marked and constantin the spinal cord. There was an enormous increase in theglial element in the spinal cord, in the ma-jority of cases examined. The marginalglia was greatly increased and the anteriorand lateral columns contained a very largeamount of fibre-forming glia. This in-crease was not confined to the white sub-stance of the cord, but the gray substancealso was involved. In som
