    immediately beneath the pericranium, adhered very closely to the subjacent bone, and formed, so far as it extended, a raised margin around the effused blood. The sensation it conveyed to the finger was very similar to that which is communicated by the osseous ring that usually surrounds these effusions, though its edge wanted something of the sharpness which that presents. The subjacent surface of the parietal bone was rough and uneven; a condition which, moreover, was not confined to that situation, but existed over a large extent of the bone. This roughness seemed to be owing to the deposit of new osseous matter, which apparently had formed the medium of the firm connection that existed between the clot and the surface of the skull.# The frontal and left parietal bone were much more vascular than usual, though otherwise healthy ; the membranous sutures were in a perfectly natural condition. The sutures were now cut up, and the right parietal bone was removed. Before this was done, however, a fissure was noticed in the bone, running from the coronal suture, about an inch from the anterior fontanelle, obliquely backwards and up¬ wards. The edges of this fissure, at the time of making the examination, were quite clean, not stained with blood as they afterwards appeared. On the inner surface of the bone was an effusion of blood between the cranium and the dura mater, more than half an inch in thickness, and occupying * See PI. IV. fig. 1,
