The bones of the cranium were unusually thick. The dura mater, which
was thickened, and in many places bore marks of former inflammation,
adhered to the bone at the vertex. On its internal surface, near the
longitudinal sinus, there was a small ossified portion, half an inch
long and the eighth of an inch thick. The convolutions of the brain
were narrow, and very strongly marked. The pia mater bore marks of
pretty extensive inflammation, and adhered to the dura mater at the
vertex. The cortical substance ran deep into the medullary part of
the brain. The ventricles contained about double the usual quantity of
water; their parts were all remarkably well defined. The vessels of
the pia mater, over the corpora striata, were unusually injected with
blood. The velum interpositum was very firm; the plexus choroides
uncommonly thick, but pale; the opening from the right to the left
ventricle large. The vessels of the brain were generally not much
filled with blood.
The blood appeared every where fluid, except in some portions of the
lungs, and in the cavities of the heart. It was very dark coloured,
perhaps more than ordinarily thin, and oozed from every part, which
was cut.
The cellular membrane, in all dependent parts, effused, when cut, a
serous fluid.
