I am thus particular in stating my instructions, because I determined to see what could be done by hygienic measures, and others directed to the relief of the supposed cerebral congestion, without resorting to the use of drugs, so long as it was probable they would not be required. Opium and other medicines of the narcotic class would, I was satisfied, do more harm than good; bromide of potassium I reserved for use, should it become necessary to employ it. I have every reason to believe that he complied faithfully with the directions given him, and ere long marks of decided improvement were visible. His pulse had fallen to 80, was regular and full; there was no more headache or vertigo; his eyes had lost their bloodshot appearance, and above all, his sleep had become sound, and was of from seven to eight hours’ duration nightly. As soon as he got settled in his easy chair for the night his eyelids began to close, and he slept steadily on till it was time for him to get up for the day. Three weeks were necessary to bring about these results in full, although amendment was manifested from the first. Yesterday, May 18th, I wrote him a note, requesting his permission to make use of his case in illustration of this memoir. The following is his answer: it is the first time he has written a line for a month: “MY DEAR DOCTOR:--If, in your opinion, my case is possessed of any value in a pathological point of view, I hope you will make such use of it as will best serve the ends of science. I make only one condition. You know I am a literary man, and that my reputation as a student and author would suffer in the estimation of the critics were I suspected of insanity. It takes very little to form a foundation for such an assumption, and, perhaps, in my case, there would be more truth than fiction in the notion as applied to me. With the exception, therefore, of giving my name, you are at perfect liberty to dish me up for the satisfaction of all your medical friends. “I shall come and see you to-morrow, and in the mean time believe me ever, “Yours sincerely and gratefully, “---- ---- ----.” “P.S.--I have read the above over, and to my great delight find that I have said what I wanted to say. I would stand on my head with joy, were it not that you were desirous of keeping as much blood out of my noddle as possible. _Laus Deo._ Can I go to work Monday?”
