CLIMATE AND HEALTH. visitors to Florida. By misrepresentations (to use a mild term) tourists and invalids have been led to believe that the entire water-supply is productive of disease, and as a consequence they refrain from drinking a sufficient quan- tity of water, or dilute it with poor whisky or brandy, to counteract its bad effects. Interested parties have expa- tiated so much with regard to the air being charged with malaria in winter, that invalids and patients become alarmed, and as a sequence they daily swallow quinine, and thereby produce nervous or functional derangements. They keep the pure air out of their rooms, breathe an air con- taminated with their own breaths and exhalations, and at night assemble in halls and parlors and inhale vitiated air poisoned by their own breaths, and the elements resulting from the combustion of coal-gas and kerosene. They in- hale, for hours at a time, air charged with carbonic acid, and shun the pure night air as they would the emanations of the deadly upas-tree. Visitors act imprudently, and as a consequence suffer from nervous derangements, colds, and diarrhoeas, which they attribute to malaria or the cli- mate. The cause of slight indispositions affecting visitors, is not malaria, but indulgence at table, change of drinking- water, eating excessive quantities of fruit, or the inhalation of air poisoned by human breaths, or the resultants of the combustion of coal-gas and kerosene, and a deficiency of the pure air that a beneficent Creator has placed every- where within their reach. If visitors would let quinine and arsenical pills alone, control their appetites, eat moderately, inhale plenty of the salubrious air of the State, and not swelter in heated halls, parlors, and unventilated bedrooms, we should hear less of the bughear malaria. At various times since 1844, I have navigated the larger streams of this State, visited the Everglades and Lake Okechobee, and almost every bay, inlet, and river, from Cape Sable to the Suwanee River, and for over two months at a time slept in an open boat, with nothing but a simple awning stretched over the boat's boom, and in no instance did my compan- ions or self suffer from malaria or a chill. Before I became a resident of the State, my companions and self were unac- climated, and in no instance were we so foolish as to swal- low quinine, arsenic, or alcoholic liquors as antidotes to ma- laria or chills. I speak from personal observation, experi-
