The essential principles in the prevention of tuberculosis consist of first, the early recognition of the disease, so that the patient may be properly treated and cured, if possible, with the result that a new center of contagion is avoided; second, the rendering of well-developed cases harmless by suitable isolation and proper disposal of infected excretions; third, the disinfection of the rooms, clothing, linen and surroundings of tuberculous patients. A fourth point, the prohibition of marriage among the tuberculous, is of great consequence, although we have little ground to hope for its realization on account of sociologic considerations. A fifth point, not yet fully established, is the possibility of universal vaccination against the disease.In most cases the burden of early diagnosis falls on the family physician, and in addition to the usual clinical and bacteriologic methods of examination, the use of tuberculin is often of value when given
