The question of house infection by tuberculosis is a rather important subject, but one that heretofore has not been extensively studied in a statistical way. There has been an abundance of proof that invalids with the disease can temporarily infect their surroundings, and that dark and ill-ventilated tenements in the slums can retain the infection to all appearances. There have, however, so far as we are aware, been but very few exhaustive comparative studies of house infection under varying conditions as to sanitation; this alone can be considered a satisfactory method of investigation of this subject. What we want to know is not merely how far and how long tuberculosis germs can retain their vitality and virulence under specially favoring conditions, but how they exist and behave under ordinary and average ones. and also in those of better than average as regards general hygienic surroundings.
