About one half of the families whom I have attended for many years, left the city. Of those who remained, many were affected by the disease. Out of the whole of them, after I had adopted my second mode of practice, I lost but five heads of families, and about a dozen servants and children. In no instance did I lose both heads of the same family. My success in these cases was owing to two causes: 1st, To the credit my former patients gave to my public declaration, that we had only _one_ fever in the city: hence they applied on the _first_ day, and sometimes on the _first_ hour of their indisposition; and 2dly, To the numerous pledges many of them had seen of the safety and efficacy of copious blood-letting, by my advice, in other diseases: hence my prescription of that necessary remedy was always obeyed in its utmost extent. Of the few adults whom I lost, among my former patients, two of them were old people, two took laudanum, without my knowledge, and one refused to take medicine of any kind; all the rest had been worn down by previous fatigue. I have before said that a great number of the blacks were my patients. Of these not one died under my care. This uniform success, among those people, was not owing altogether to the mildness of the disease, for I shall say presently, that a great proportion of a given number died, under other modes of practice. In speaking of the comparative effects of purging and bleeding, it may not be amiss to repeat, that not one pregnant woman, to whom I prescribed them, died, or suffered abortion. Where the tonic remedies were used, abortion or death, and, in many instances, both, were nearly universal. Many whole families, consisting of five, six, and, in three instances, of nine members, were recovered by plentiful purging and bleeding. I could swell this work by publishing a list of those families; but I take more pleasure in adding, that I was not singular in my success in the use of the above remedies. They were prescribed with great advantage by many of the physicians of the city, who had for a while given tonic medicines without effect. I shall not mention the names of any of the physicians who _totally_ renounced those medicines, lest I should give offence by not mentioning them all. Many large families were cured by some of them, after they adopted and prescribed copious purging and blood-letting. One of them cured ten in the family of Mr. Robert Haydock, by means of those remedies. In one of that family, the disease came on with a vomiting of black bile. But the use of the new remedies was not directed finally by the physicians alone. The clergy, the apothecaries, many private citizens, several intelligent women, and two black men, prescribed them with great success. Nay more, many persons prescribed them to themselves, and, as I shall say hereafter, with a success that was unequalled by any of the regular or irregular practitioners in the city.
