But there has come another signal advantage in the point of view adopted by Calmette in his dispensary campaign--the point of view, namely, of public health and public good. It has freed us from the limitations contained in the old idea that a dispensary is an institution concerned solely with the poor. Tuberculosis, of course, like every other infectious disease pays but little respect to distinctions of property. From the point of view of the State a tuberculous individual is as dangerous to others and a cured tuberculous patient is as valuable as a possible asset to the State, whether his income is above or below a certain figure, whether, in other words, he is inside or outside the imaginary group sometimes called the poor. From the institution of tuberculosis dispensaries with their home visitors in America, the poverty of the individual ceased to be a necessary badge for admission. Especially since many of our dispensaries have been instituted and maintained by the State, and therefore are paid for by all its citizens in their taxes, any one so unfortunate as to acquire tuberculosis, or be suspected of it, feels himself wholly justified in seeking help at a State-maintained tuberculosis dispensary. In this respect, as in many others, the campaign against tuberculosis has had a value far greater than its measure of success in checking that disease. It has introduced methods which were applicable outside the field of tuberculosis. One of these, as I have already said, was the utilization of the home visitor. A second was the disregarding of property lines. A third was the frank and confident reliance upon scientific measures and the relegation of eclecticism and quackery to the hands of those who make no pretence at scientific education or honest dealings with the public.
