SYPHILIS OF THE SPINAL CORD. 339 teritis is quite as frequent as an inflammation of the endo-thelium alone. Bruce has directed attention to changes inthe adventitia (nodose periarteritis); moreover, veins aresubject to syphilitic changes quite as often as the arteriesare (phlebitis obliterans, Greiff). All these vascular changesare much more pronounced in the pial covering than in thesubstance of the spinal cord. The investigations of other authors, as well as my own,.

The diseasestarts, as a rule, in the pia, and subsequently invades thespinal cord. There can be little doubt, however, that thechanges may in some instances be developed in the reverseorder. In the gross specimen we find the pia thickened and 34° THE NERVOUS DISEASES OF CHILDREN. often covered by a thick gelatinous substance. On micro-scopical examination this thickening is seen to be due to aproliferation of all the tissues. The cells are multiplied innumber, t
