The time is not far distant when every town that owns a public hall will also have its public baths. Before that time comes, physicians ought to moderate the charges for these remedial agents. Outside of our large cities, the cost of taking sulphur vapor-baths is $5 each, and they are given only in series, as prescribed by the judgment or humor of the physician. When will people learn the laws and habits of their own bodies, so that they need not be at the mercy of every specialist who chooses to make money out of their emergencies? For the benefit of outsiders it ought to be said that the charge in the best establishments of New York is not higher than $2 50 for the single bath, and a great reduction from this is common. The essential difficulty of the sulphur vapor treatment is to keep from the face the powerful fumes, which are dangerous to breathe. For this object the bather enters a wooden box, with a cover that fits the neck. She takes a seat in the box undressed, and the cover is adjusted so that only the head is left out. Cloths or a rubber collar are closely drawn about the neck to prevent the least escape of gas, and a wet sponge is laid on the top of the head, or, what is better, a very wet towel folded turbanwise round the back of it, and over the top, thus cooling the base of the brain, the side arteries, and sensitive upper part. This compress must be frequently wet with cold water during the bath--a precaution which removes the danger of apoplectic seizures by the intense heating of the blood. Steam charged with sulphur is then let into the box by pipes, and in three minutes the perspiration flows as if the luckless victim were melting away. In the best establishments an attendant fans the bather all the time the steam is let on, to cool the head, into which the heated blood rushes in a way that makes the wet towel smoke directly. And this is an attention the patient must insist upon, for faintness or apoplexy may be the alternative.
