Hygiene in regard to patients demands simply that the infectious character of the expectoration be destroyed. The vessels for this purpose should contain some disinfecting solution, should be cleaned regularly, and handkerchiefs, towels, or other material with which the expectoration has come in contact should be sterilized by being placed for at least half an hour in boiling water. This is necessary not only for those in the same room with the patient, but also for the patient, as it is quite possible that a former expectoration may produce reinfection of the patient himself. Another method of contracting tuberculosis is by means of animals, such as cows, used for food and milking, which are known to be subject to this disease. It has been shown in some localities that one cow out of every twenty-five was affected with tubercular disease. This suggests the importance of having competent veterinarians to examine not only the meat which is sold, but also the cows used for milking purposes. Where there is the slightest doubt as to the nature of the meat or milk, the former should be thoroughly cooked and the latter sterilized before using. In this connection it would be well to refer to the subject of spitting in street cars and in public places. While this nuisance is the subject of danger to every one in the street cars, especially in winter, when the windows are closed and a large amount of impurities is inhaled, it is more particularly so to ladies, whose skirts, in spite of every care, are soiled by the filthy expectoration, thus making them subject not only to the inhalation in the car, but also to carrying the infectious material to their homes. The danger of this condition is not merely speculative. It has been bacteriologically demonstrated that the organisms of various contagious diseases thus find a lodging place in our cars and public places, and experiments on animals, in which the inoculation has developed diseases, have shown that these organisms retain their vitality in these places and may propagate disease under favorable conditions. A factor in the spread of diseases of the throat and mouth that should not be overlooked is kissing. Unfortunately, this matter has usually been treated with much levity, and where a sanitarian is bold enough to condemn the habit he is frequently made the subject of all forms of ridicule in the public press.
