It was said a practitioner, who was opposed to bleeding and mercury, cured this fever by means of strong emetics. I gave one to a man who refused to be bled. It operated freely, and brought on a plentiful sweat. The next day he arose from his bed, and went to his work. On the fourth day he sent for me again. My son visited him, and found him without a pulse. He died the next day.
I heard of two other persons who took emetics in the beginning of the fever, without the advice of a physician, both of whom died.
Dr. Pinckard informed me, that their effects were generally hurtful in the violent grades of the yellow fever in the West-Indies. The same information has since been given to me by Dr. Jackson. In the second and third grades of the bilious fever they appear not only to be safe, but useful.
OF DIET AND DRINKS.
The advantages of a weak vegetable diet were very great in this fever. I found but little difficulty, in most cases, in having my prohibition of animal food complied with before the crisis of the fever, but there was often such a sudden excitement of the appetite for it, immediately afterwards, that it was difficult to restrain it. I have mentioned the case of a young man, who was upon the recovery, who died in consequence of supping upon beef-stakes. Many other instances of the mortality of this fever from a similar cause, I believe, occurred in our epidemic, which were concealed from our physicians. I am not singular in ascribing the death of convalescents to the too early use of animal food. Dr. Poissonnier has the following important remark upon this subject. “The physicians of Brest have observed, that the relapses in the malignant fever, which prevailed in their naval hospitals, were as much the effect of a fault in the diet of the sick as of the contagious air to which they were exposed, and that as many patients perished from this cause as from the original fever. For this reason light soups, with leguminous vegetables in them, panada, rice seasoned with cinnamon, fresh eggs, &c. are all that they should be permitted to eat. The use of flesh should be forbidden for many days after the entire cure of the disorder[3].”
Dr. Huxham has furnished another evidence of the danger from the premature use of animal food, in his history of a malignant fever which prevailed at Plymouth, in the year 1740. “If any one (says the doctor) made use of a flesh or fish diet, before he had been very well purged, and his recovery confirmed, he infallibly indulged himself herein at the utmost danger of his life[4].”
In addition to the mild articles of diet, mentioned by Dr. Poissonnier, I found bread and milk, with a little water, sugar, and the pulp of a roasted apple mixed with it, very acceptable to my patients during their convalescence. Oysters were equally innocent and agreeable. Ripe grapes were devoured by them with avidity, in every stage of the fever. The season had been favourable to the perfection of this pleasant fruit, and all the gardens in the city and neighbourhood in which it was cultivated were gratuitously opened by the citizens for the benefit of the sick.
The drinks were, cold water, toast and water, balm tea, water in which jellies of different kinds had been dissolved, lemonade, apple water, barley and rice water, and, in cases where the stomach was affected with sickness or puking, weak porter and water, and cold camomile tea. In the convalescent stage of the fever, and in such of its remissions or intermissions as were accompanied with great languor in the pulse, wine-whey, porter and water, and brandy and water, were taken with advantage.
Cold water applied to the body, cool and fresh air, and cleanliness, produced their usual good effects in this fever. In the external use of cold water, care was taken to confine it to such cases as were accompanied with preternatural heat, and to forbid it in the cold fit of the fever, and in those cases which were attended with cold hands and feet, and where the disease showed a disposition to terminate, in its first stage, by a profuse perspiration. It has lately given me great pleasure to find the same practice, in the external use of cold water in fevers, recommended by Dr. Currie of Liverpool, in his medical reports of the effects of water, cold and warm, as a remedy in febrile diseases. Of the benefit of fresh air in this fever, Dr. Dawson of Tortola has lately furnished me with a striking instance. He informed me, that by removing patients from the low grounds on that island, where the fever is generated, to a neighbouring mountain, they generally recovered in a few days.
