Pepper, the arachnoid is usually smooth and trans- parent. I have never seen any marked change in it.. The pia mater in the earlier stages of the disease- is much congested, and is variegated in color from a deep scarlet to shrimp-pink or a delicate salmon. Sometimes there are superficial deposits of purulent matter. The perivascular spaces contain a purulent in- filtrated exudation of turbid yellow, sage-green, or gray serosity, in which are many migrating blood cor- puscles. Sometimes the convolutions are repressed,., flattened, and ischsemic. Frequently the pia mater is found covered with pus, and firmly attached to the cortex. This is very- common in idiocy. The brain itself may be covered with lymph or pus, which may also contain numbers of leucocytes. In children the cerebrum is apt to be much softened..
