The reasons which induced me to prescribe purging and bleeding, in so liberal a manner, naturally led me to recommend _cool_ and _fresh air_ to my patients. The good effects of it were obvious in almost every case in which it was applied. It was equally proper whether the arterial system was depressed, or whether it discovered, in the pulse, a high degree of morbid excitement. Dr. Griffitts furnished a remarkable instance of the influence of cool air upon the fever. Upon my visiting him, on the morning of the 8th of October, I found his pulse so full and tense as to indicate bleeding, but after sitting a few minutes by his bed-side, I perceived that the windows of his room had been shut in the night by his nurse, on account of the coldness of the night air. I desired that they might be opened. In ten minutes afterwards the doctor's pulse became so much slower and weaker that I advised the postponement of the bleeding, and recommended a purge instead of it. The bleeding notwithstanding became necessary, and was used with great advantage in the afternoon of the same day. The cool air was improper only in those cases where a chilliness attended the disease. For the same reason that I advised cool air, I directed my patients to use cold _drinks_. They consisted of lemonade, tamarind, jelly and raw apple water, toast and water, and of weak balm, and camomile tea. The subacid drinks were preferred in most cases, as being not only most agreeable to the taste, but because they tended to compose the stomach. All these drinks were taken in the early stage of the disease. Towards the close of it, I permitted the use of porter and water, weak punch, and when the stomach would bear it, weak wine-whey. I forbade all cordial and stimulating food in the active state of the arterial system. The less my patients ate, of even the mildest vegetable food, the sooner they recovered. Weak coffee, which (as I have formerly remarked) was almost universally agreeable, and weak tea were always inoffensive. As the action of the pulse diminished, I indulged my patients with weak chocolate; also with milk, to which roasted apples, or minced peaches, and (where they were not to be had), bread or Indian mush were added. Towards the crisis, I advised the drinking of weak chicken, veal, or mutton broth, and after the crisis had taken place, I permitted mild animal food to be eaten in a small quantity, and to be increased according to the waste of the excitability of the system. This strict abstinence which I imposed upon my patients did not escape obloquy; but the benefits they derived from it, and the ill effects which arose in many cases from a contrary regimen, satisfied me that it was proper in every case in which it was prescribed.
