- This disease is most prevalent in hot climates, and southern cities of our country. It comes in the latter part of summer, and lasts till frosty weather. The disease begins with a chill, generally not very severe. Following the chill, there is moderate fever, and some heat of the surface; but this rarely rises to any great height, and only continues to the second or third day, when, in fatal cases, it gives place to coldness of surface, etc. In many cases there is sweating. The pulse is peculiar, not often over a hundred, but feeling like a bubble under the finger, which breaks and vanishes before it can be fairly felt. The tongue is moist and white in the first and second days; but red, smooth, shining and dry as the disease advances toward the close, having a dry, black streak in the middle. The most striking symptoms are nausea and vomiting, which, in fatal cases, is very persistent; and toward the last a yellowish or greenish matter is thrown up, followed by a discharge of thin black fluid, which is called the black vomit. The bowels are generally costive, with tenderness in the upper bowels or stomach. There is generally severe headache, and a peculiar expression of face, in which the lips smile, while the rest of the face is fixed and sad, sometimes wild. The patient continues wakeful night and day. There are discharges of blood, often from the nose, the gums, the ears, the stomach, the bowels, and the urinary passages. First move the bowels with some mild physic, such as sweet tincture of rhubarb, four ounces; bicarbonate of soda, two drachms. Mix. Give a table-spoonful once in three hours until it operates. During the chill, use all the usual means of warming the body - by hot bottles, mustard foot-bath, warm drinks, draughts, etc. A warm poultice on the stomach is useful - some would advise cupping. During the second, or calm stage, give gentle stimulants, warm drinks, and five-drop doses of veratrum viride, also quinine. In the third stage, brandy, quinine, and all stimulants freely. To quiet the vomiting, give of this preparation: creosote, twenty drops; spirits of mindererus, six ounces; and alcohol enough to dissolve the creosote. Dose - half an ounce, every two hours.

Temperance, cleanliness, and all good habits, do much to prevent this disease. A French physician asserts that liability to yellow fever is prevented by drinking only boiled water. He believes that the fever is the exclusive result of using corrupted water, and that, if one is attacked by it, he may be cured in a few hours by drinking large quantities of boiled water. Many of our best authorities believe that infusoria is the cause of the disease.
