    most exposed to such exhalations, I have suffered with slight fever, loss of appetite, and nausea (these symptoms, however, were not of sufficient severity to cause the intermission of my labors) ; and such ob- servations have led me to the belief that under certain circumstances the poison of yellow fever may pass through the system, producing slight derangement, without inducing the disease itself. During the prosecution of similar investigations in smallpox, I have in like manner felt the depress- ing influence of the poison without manifesting well- marked symptoms of this disease; and upon one occasion, after exposure to the smallpox poison in the crowded tents of a Confederate military smallpox hospital, and after performing a protracted po.si- mortem upon the body of a Confederate soldier who had died with confluent smallpox, I suffered with fever, intense pain in the back and head, and injec- tion of the capillaries of the skin. These symptoms disappeared, however, at the end of three days. It was evident that the protective influence of the vac- cine virus introduced into my arm twenty-five years before was sufficient to cause or allow the pabsage of the smallpox poison in large amount through the system, with only a partial and mild manifestation of some of the symptoms usual in those unprotected either by vaccination or by a previous attack of smallpox. Ip the case of the yellow fever poison, there was no known state of the system artificially produced, as in the case of the smallpox poison, which would account for the elimination of the poison; although that such an elimination must have taken place was manifest from the peculiar train of symptoms attend- ing prolonged exposure to the exhalations of the sick and dead. Of the various students numbering over one hun- dred, and many of them fresh from the country, who have observed cases of yellow fever in my wards in the Charity Hospital and witnessed post-mortem esiSim-
