The treatment in a cerebral case of moderate severity has been already sufficiently explained. Blood must be drawn to the subdual of the inflammation, and if blood be abstracted early, two, or at most three, moderate bleedings will be all that will be required. But when the attack commences with severe cerebral affection, the bleeding must be proportionally large, and early as it is copious. A bleeding adequate to subdue a moderate, will be utterly inert in a severe degree of cerebral disease. I give, as a specimen of what may be sometimes required, the case of Dr. DILL. I saw my friend at the very commencement of his attack, and was, therefore, able to carry into effect what I conceive to be the proper treatment with due promptitude and vigour. I saw him before there was any pain in the head, or even in the back, while he was yet only feeble and chilly. The aspect of his countenance, the state of his pulse, and the answers he returned to two or three questions, satisfied me of the inordinate, I may say the ferocious, attack that was at hand. Having taken an emetic without delay, as soon as its operation was over, blood was taken from the arm to the extent of twenty ounces. During the night, severe pain in the limbs, especially in the loins, and intense pain in the head came on. The blood that was taken on the preceding evening was not inflamed. Early in the morning he was again bled to the extent of about sixteen ounces, with great diminution, but not entire removal of the pain: the pain not lessening, towards the afternoon he was again bled to the same extent: the pain was now quite gone; the blood from both these bleedings was intensely inflamed. During the night the pain returned, and, in the morning, the eyes were dull and beginning to be suffused, while the pulse continued slow and intermittent, and the respiration suspirious; but the face was blanched, and the pulse, in addition to its other characters, was weak. Instead of opening the vein afresh, twelve leeches were applied to the temples; these very much relieved, but still did not entirely remove the pain; for this reason, he was cupped to the extent of sixteen ounces: this operation afforded very great relief, and he continued easy until the following evening, when the pain returned, and he was again cupped on the temples to the same extent. Immediate relief followed this second operation; but, unfortunately, the pain returned with great violence towards evening, and it was now impossible to carry the bleeding any farther. Within twenty-four hours, it was plain that typhoid symptoms in abundance would be present, for the fur on the tongue was becoming brown, and there was already slight tremor in the hands. No more blood could be taken with any prospect of advantage, nor even with safety; yet, without the aid of some powerful remedy the case was lost.
