once with mercuric bi-chloride. Cloths must be used instead of handkerchiefs, and then burned, or, if the latter are used, they should be often changed, and immediately put in a bi-chloride solution and boiled. Bed-linen should be treated in the same way. Frequent disinfection of the entire person, and fumigation of the apartment, would be safe additions to the preventive measures. 4. Persons who have a marked predisposition to the disease had best not come in close contact with the phthisical. Children should never have tuberculous nurses, wet or dry. In the case of consumptives very great attention should be paid to ventilation, and to the alimentation both of the patient and the attendants. Such measures, if rigidly carried out, would be of enormous service in preventing this disease. But with the increasing prevalence of tuberculosis among domestic animals, something more is imperatively demanded. Active measures should be taken to free the country from animal tuberculosis. There are some ideas which it is well to observe:-- 1. Flies may carry the virus if they are allowed to frequent cuspidors into which consumptives have expectorated. Clean these out often. Do not permit the patient to spit into a handkerchief and then let it lie around to dry. The dust arising may inoculate some person prone to consumption. 2. Be careful about the meat you eat. It can and does convey tuberculosis. Investigations have been made showing that as high as 50% of a herd to be slaughtered in New York City had tuberculosis. Milk may be also infected and often is. 3. Have an abundance of flowers around. They invariably are helpful. 4. Constant and regular singing with proper care and not tiring is excellent for consumptive lungs, which should be done in well-ventilated rooms. 5. Be out in the open air as much as possible, and breathe through the nose entirely. Continually exercise the lungs by drawing in long breaths. 6. If possible try fumes of hydrofluoric acid. In glass factories if workmen are rendered consumptive by stooping over the grinding machinery, they usually find great benefit by being allowed to work in the room with the glass etchers, where so much hydrofluoric acid is employed. 7. Buttermilk is well recommended. 8. Consumptive and bronchial troubles in women are often due to irregularity of dress about the throat and lungs. There is danger from wearing _d'ecoll'ete_ costumes. So regular have we been in our habits that the throwing off of a 1-oz. neck-tie for half an hour in the open air will give us a cold with the thermometer at 70% Fahr. The ocean cure is well set forth in the following, which represents the advantages of a long sea voyage:-- 1. Perfect rest and quiet, and complete removal from and change of ordinary occupation and way of life; a very thorough change of scene, and perfect and enforced rest from both mental and physical labor.
