exclusively affected; the convulsions recurred several times during the next twenty-four hours, and in the intervals he remained almost completely unconscious. The mercurial treatment was pushed, in the form of calomel-powders placed on the tongue. On the evening of the 18th he began to recover consciousness, and then had a little natural sleep; the next morning, at 10 A. M., he was found to be fully conscious, had had no return of convulsions, but the left arm and leg, especially the latter, were almost entirely powerless; the parietal headache had vanished; the gums were slightly tender; the third and sixth nerves of right side were completely paralyzed. Mercurial treatment was very gently continued, so as to keep the patient on the borders of ptyalism for the next three or four days; and he was then put on full doses of iodide of potassium. The pain never recurred; the left extremities recovered power rapidly; but it was six weeks before the ocular paralyses were completely well. Late in the autumn of 1865 I was sent for hastily one evening to see this same man, and found him totally unconscious and apparently again hemiplegic, but now on the right side. He was miserably wasted, and covered with a rupious eruption; I was informed that he had been leading a most debauched and drunken life for some time past, and that, after looking extremely ill, and apparently half imbecile for a week or two past, he had suddenly fallen down unconscious in the street a few hours before I saw him. He remained deeply comatose, and died the next morning; no _post mortem_ could be obtained.
