DON'T cough without holding your handkerchief or your hand over your mouth. DON'T live in rooms where there is no fresh air. DON'T work in rooms where there is no fresh air. DON'T sleep in rooms where there is no fresh air. Keep at least one window open in your bedroom day and night. Fresh air helps to kill the consumption germ. Fresh air helps to keep you strong and healthy. DON'T eat with soiled hands; wash them first. DON'T NEGLECT A COLD or a cough. To be sure, the precept of "Don't spit," as applied in cities, has other reasons for enactment than to prevent tuberculosis. Spitting is a filthy habit, and its practice should be decried on the score of cleanliness whether on the streets or in any public place, so that the signs now seen in street cars and railroad trains, in halls and office buildings, are intended not altogether for consumptive patients, but also for those who need laws to force them to observe ordinary rules of cleanliness and decency. It is, however, the main step towards doing away with consumption, and the faithful observance of the injunction ought to be insisted upon quite as much in the individual home as in a city street or public building. Case after case has been cited of instances where one consumptive patient in a family has spread the disease through the household, and, at intervals of a year or so, one after another of the family has succumbed to the attacks of the consumptive germ, when by proper precautions and suitable care of the sputum of the first sick person, the other deaths might have been prevented. _Individual resistance to tuberculosis._ There is a remarkable difference in the ability of individuals to withstand the attacks of this disease, and it will be found always that the first to succumb are those whose vitality has been in some way depleted. The women of the family, who are generally confined to the house, who do not have their lungs reenforced by a continual influx of fresh air, who are tired and worn out with their household duties, give themselves an easy prey to the attacks of the bacteria, while the men and boys, who are more outdoors, who are vigorous and strong, throw off the attack and are not affected.
