In the treatment of the influenza I was governed by the state of the system. Where inflammatory diathesis discovered itself by a full or tense pulse, or where great difficulty of breathing occurred, and the pulse was low and weak in the beginning of the disease, I ordered moderate bleeding. In a few cases in which the symptoms of pneumony attended, I bled a second time with advantage. In all these instances of inflammatory affection, I gave the usual antiphlogistic medicines. I found that vomits did not terminate the disease, as they often do a common catarrh, in the course of a day, or of a few hours. In cases where no inflammatory action appeared in the system, I prescribed cordial drinks and diet, and forbad every kind of evacuation. I saw several instances of persons who had languished for a week or two with the disease, who were suddenly cured by eating a hearty meal, or by drinking half a pint of wine, or a pint of warm punch. In all these cases of weak action in the blood-vessels, liquid laudanum gave great relief, not only by suspending the cough, but by easing the pains in the bones. I met with a case of an old lady who was suddenly and perfectly cured of her cough by a fright. The duration of this epidemic in our city was about six weeks. It spread from New-York and Philadelphia in all directions, and in the course of a few months pervaded every state in the union. It was carried from the United States to several of the West-India islands. It prevailed in the island of Grenada in the month of November, 1789, and it was heard of in the course of the ensuing winter in the Spanish settlements in South-America.
