=Disinfectant.= The most expensive of the supplies is the disinfectant, which is also probably the least valuable. That used in Baltimore is a special preparation, consisting largely of creolin; it is put up in pint bottles by one of the large wholesale drug houses. For use, it is diluted in water, a tablespoonful to a pint, and used in wiping up floors, furniture, and so forth. It is of necessity too dilute to have much germicidal action, and the patients place far too much reliance upon its odor—which, to the ignorant mind, is of prime importance. Although we use this disinfectant, we prefer to teach our patients that better results may be obtained by the lavish use of hot water, brown soap, and a scrubbing brush, and that thorough cleaning of this kind is of more value than the most malodorous drug ever dispensed. Disinfectant to be of real use must be strong and powerful, and it is dangerous to distribute such powerful drugs promiscuously. Several of our patients have tried to commit suicide by drinking even the weak preparation that we gave them. On the whole, we believe that an anti-tuberculosis society would lose nothing by omitting disinfectant from its list of prophylactic supplies, and better results could be obtained by substituting a thorough grounding as to the value of soap and water. =Waterproof Pockets.= These are little calico bags, dipped in paraffin, or some similar preparation which makes them fairly waterproof. These are pinned inside the coat pocket, and the patient uses them as a receptacle for his soiled napkins, when he is out on the street, or in other places where he cannot carry his sputum cup. The napkins are burned upon his return. =Books of Instruction.= These little books are more or less valuable, but are by no means intended to take the place of the verbal instruction which it is the nurse’s duty to give. They serve merely to refresh the memory after she has gone. They can be procured at small cost through the various anti-tuberculosis organizations, and most Boards of Health print them for their own distribution. The best of them are inadequate. =Stocking the Bag and Distributing Supplies.= When the nurse starts forth on her morning rounds, her bag should contain enough supplies for the patients she proposes to call on. Each should be given enough to last until her next arrival. It is sometimes possible to direct either the patient himself, or some member of his family, to come to the office and get a fresh stock whenever necessary. By putting this slight responsibility on the family, it is made to realize how necessary are these supplies, but it should not relieve the nurse of her obligation to visit such a household, and keep it under as close observation as any other case. If a nurse thus trains a certain number of patients to come themselves for the supplies, she will be able to reserve the contents of her satchel for those patients who cannot call for them, or who are too indifferent to do so.
