1. Notwithstanding the numerous proofs of the prevalence of the yellow fever in Philadelphia in the year 1794, which have been mentioned, there are many thousands of our citizens, and a majority of our physicians, who do not believe that a case of it existed at that time in the city; nor is a single record of it to be met with in any of the newspapers, or other public documents of that year. Let us learn from this fact, that the denial of events, or a general silence upon the subject of them, is no refutation of their truth, where they oppose the pride or interests of the learned, or the great. 2. Notwithstanding the general denial of the existence of the yellow fever in Philadelphia, and the silence observed by our newspapers relative to it in 1794, there was scarcely a citizen or physician who, three years afterwards, did not admit of its having prevailed in that year. We learn from this fact another important truth, that departed vice and error have no friends nor advocates. OF THE METHOD OF CURE. The remedies employed for the cure of this fever were the same that I employed the year before. I shall only relate such effects of them as tend more fully to establish the practice adopted in the year 1793, and such as escaped my notice in my former remarks upon those remedies. My method of cure consisted, I. In the abstraction of the stimulus of blood and heat from the whole body, and of bile and other acrid humours from the bowels, by means of the following remedies: 1. Bleeding. 2. Purging. 3. Cool air and cold drinks. 4. Cold water applied to the external parts of the body, and to the bowels by means of glysters. II. In creating a diversion of congestion, inflammation, and serous effusion, from the brain and viscera to the mouth, by means of a salivation, and to the external parts of the body, by means of blisters. III. In restoring the strength of the system, by tonic remedies. I proceed to make a few remarks upon the remedies set down under each of the above heads. I. I have taken notice that this fever differed from the fever of 1793, in coming forward in July and August with a number of paroxysms, which refused to yield to purging alone. I therefore began the cure of every case I was called to by _bleeding_. I shall mention the effects of this remedy, and the circumstances, manner, and degrees in which I used it occasionally, in this fever, in my Defence of Blood-letting. Under the present head I shall only furnish the reader with a table of the quantity of blood drawn from a number of my patients in the course of the disease. From several of them the quantity set down was taken in three, four, and five days. I shall afterwards describe the appearances of the blood.
