I would remark that, with these remedies applied as here recommended, my brother, Dr. G. S. HILL, of Erie County, Ohio, has, during the last four months, treated a large number of those malignant sore-throats, (the "Black tongue Erysipelas,") and been universally successful, relieving them in a few hours, when the symptoms were of the most alarming character, and the disease in some cases, so far advanced that the patients were considered by their friends and attendants, "at the point of death." The _Hydrastin_ is a most potent remedy in putrid ulcerations of the mucous surfaces, and much the same may be said of _Eupatorium aromaticum_. Yellow Fever. [As I have never practiced farther South than Cincinnati, and have seen but few cases of this disease, my experience with it has not been sufficient to be relied upon as authority. Therefore, I shall give a brief description of the disease, with the proper and _successful treatment_, furnished me by A. H. BURRETT, M. D., of New Orleans, who is not only a Physician of more than ordinary learning and skill in his profession generally, but is one who has spent his time in New Orleans among the sick of Yellow Fever, through three of the most fatal epidemics that ever scourged any city. He is a man for the times, a man of resources, who draws useful lessons from experience and observation. Hence he has been able to select such remedies as have enabled him to cope most successfully with the pestilence, saving nearly all his patients, while, under other treatment, a majority have died. I therefore, attach great value to his treatment, and recommend its adoption with the most implicit confidence.] * * * * * When this Fever prevails as an epidemic, as it usually does, in the southern part of the United States, it is a disease of the most malignant character. The proportion of _fatal_ cases under the Allopathic course of treatment, has been equal to, and, in some places, as in New Orleans, and some Towns in Virginia, has exceeded that of _Asiatic_ Cholera. It is almost entirely confined to Southern regions, and only prevails in hot weather, after the continuance of extreme heat for some weeks.
