The dura raater included within this space w'as depressed ; its surface was in some places ulcerated, and in others black, but the raembrane w’as quite entire, and the hone was sound. On raising the dura raater, the inner sur- face of this portion had the same irregular ulcerated ap- pearance as the outer surface, and w hen held up to the light, the raembrane at the part appeared to be in some places considerably thickened, in others very thin. The right hemisphere of the brain, over all that part of it which is usually exposed in the ordinary way of open- ing the head, was covered by a thin uniform layer of very thick purulent matter, spread over it w’ith great equality, and this being removed, an extensive stratum of adventitious membrane was found under the arach- noid. It was irregular in thickness, being most re- markable on the anterior part of the hemisphere, and disappearing on the posterior part. It followed the course of the arachnoid, covering the openings of the convolutions, but not dipping between them. The pia mater betwixt the convolutions w'as highly vascular, but without any deposition. On cutting into the sub- stance of the right hemisphere, the cerebral matter was to a slight depth of a dark livid colour, but without any change of structure. There was no efl’usion in the ven- tricles, and the brain in all other respects wms quite healthy. The suppuration in the left orbit was confin- ed to a cavity betwixt the orbit and the ball of the eye, without any disease of the bones, and without any inter- nal disease on that side of the cranium. In this remarkable case, the inllammation of the dura mater appears to have been the primary disease, though it was afterwards complicated with extensive inflamma- tion of the arachnoid. The only case wdiich I have met with in any degree analogous to it, is one which IS mentioned by M. Fizcan, though it differs from it in being complicated with disease of the bone.'* A boy Journal de .''led. tom. xi. new series, p. 523. jij.](https://iiif.wellcomecollection.org/image/b21959432_0053.jp2/full/800%2C/0/default.jpg)
