When the insensibility has begun to diminish, the patient can be roused with less difficulty; if pinched, he complains of it by uttering some inarticulate sounds, or by attempting to move himself further from the quarter whence he supposes the injury to come; he answers, though with unwillingness, loud questions regarding the pain which he suffers, and points to the part where it is chiefly felt. As the stupor goes off, symptoms of inflammatory action, or a threatening of it in a greater or less degree, manifest themselves. The pulse becomes more rapid and sharp, the skin is hot and dry, the face is flushed, the conjunctiva is redder than usual, and the pupils are often much contracted: the patient is restless, and tosses about in bed; mutters confusedly to himself; often attempts to enact a part in some fanciful scene which he supposes to be passing around him, or talks rapidly and incoherently concerning circumstances which have formerly occurred. His flitting ideas are often of an alarming nature; he endeavours to get out of bed, and struggles violently if opposed. He frequently puts his hand towards his head, and gives other indications of suffering acute pain in that region, much increased by any movement of the part. Such symptoms are often followed by vomiting and rigors, and too frequently by convulsions, more furious delirium, and coma. On examination after death, an increased vascularity of the cerebral membranes is observed; there is an effusion of gelatinous-looking matter on the surface of the membranes, and in the cellular tissue beneath the arachnoid. In more advanced cases, thin patches of lymph, or more extensive strata of it, cover the arachnoid and the inner surface of the dura mater; a puriform fluid is found effused between these membranes, and sometimes blood and matter are deposited in some part of the cerebral substance; bloody serum is effused into the cavities, and at the base of the brain. The above symptoms and appearances sometimes follow injuries not at first thought severe, but are most frequently the result of such as are attended with læsion of the bone, or of the internal parts.
