[87] The hoarse barking, or the total inability of mad dogs to bark, favours still further the idea that the mortal seat of the disease is in the glottis, and that the remedy which has been proposed is a rational one. Should this new mode of attacking this furious disease be adopted, and become generally successful, the discovery will place the ingenious gentleman who suggested it in the first rank of the medical benefactors of mankind. I have only to add a fact upon this subject which may tend to increase confidence in a mode of preventing the disease which has been recommended by Dr. Haygarth, and used with success in several instances. The same dog which bit Mr. Todd's son, bit, at the same time, a cow, a pig, a dog, and a black servant of Mr. Todd's. The cow and pig died; the dog became mad, and was killed by his master. The black man, who was bitten on one of his fingers, exposed the wound for some time, immediately after he received it, to a stream of pump water, and washed it likewise with soap and water. He happily escaped the disease, and is now in good health. That his wound was poisoned is highly probable, from its having been made eight hours after the last of the above animals was bitten, in which time there can be but little doubt of such a fresh secretion of saliva having taken place as would have produced the hydrophobia, had it not been prevented by the above simple remedy. I am not, however, so much encouraged by its happy issue in this case as to advise it in preference to cutting out the wounded part. It should only be resorted to where the fears of a patient, or his distance from a surgeon render it impossible to use the knife. AN ACCOUNT OF _THE MEASLES_, AS THEY APPEARED IN PHILADELPHIA, IN THE SPRING OF 1789. The weather in December, 1788, and in January, 1789, was variable, but seldom very cold. On the first of February, 1789, at six o'clock in the morning, the mercury in Fahrenheit's thermometer fell 5° below 0, in the city of Philadelphia. At twenty miles from the city, on the Schuylkill, it fell 12° below 0, at the same hour. On the 19th and 20th of this month, there fell a quantity of snow, the depth of which, upon an average, was supposed to be about eight or ten inches. On the 23d, 24th, 25th, and 27th, the weather was very cold. The mercury fluctuated during these days between 4° and 10° above 0. In the intervals between these cold days, the weather frequently moderated, so that the Delaware was frozen and thawed not less than four times. It was not navigable till the 8th of March. There were in all, during the winter and month of March, sixteen distinct falls of snow.
