The only indications of a disordered system other than those I have mentioned were, that his pulse was too frequent (104), that it was irritable and irregular; that he had had several attacks of slight vertigo and headache; that his eyes were brilliant and somewhat congested, and that pressure upon the closed lids caused considerable pain. His bowels, contrary to what might have been reasonably expected, were regular, and his appetite was generally good. His urine contained an excess of urea and of phosphates; oxalate of lime was also present. There was nothing in his condition which appeared to give him the least anxiety, beyond the impossibility of controlling his thoughts when writing, and this he attributed directly to overexertion of his mental powers. He had, however, tried the effect of suspending his studies for two or three weeks, but had not perceived that any benefit was derived from this procedure. He had, therefore, returned to his occupations. I told him very plainly that, unless he was prepared to forego his literary labors for several weeks at least, he would be in great danger of permanent injury to his mind; but that with the avoidance of severe mental exertion, and by the aid of other measures, I believed he could be restored. He demurred somewhat to the first condition, but finally promised to follow my advice implicitly. Although I was unable to explain the fact that mental aberration should only be manifested when he wrote, I was confident that his condition was clearly the result of intense hyperæmia of the brain, and that if this could be dissipated, and sound, regular, and sufficient sleep be produced, the mental trouble would also vanish. I therefore directed that half a dozen dry cups should be applied to the nape of the neck every evening, that he should take a warm bath directly afterward, and that, while in the bath, cold water should be poured on his head. Instead of lying down when he attempted to sleep, I advised that he should assume the sitting posture, supporting his head on a hair pillow. All literary labor was to cease. Instead of the books he was in the habit of studying, he was to read novels. He was to compose himself for sleep at eleven o’clock at night, and was to rise punctually at seven; take his sponge-bath as usual, and, after eating a moderate breakfast, to do anything he liked, except studying or writing, till twelve o’clock, when he was to take a walk for an hour, then eat a biscuit, read light literature till four, and then ride on horseback till six, at which hour he was to dine, simply, but to the extent his appetite prompted him. He had been in the habit of smoking one cigar a day (after dinner), and I allowed him to continue in this indulgence.
