Analogy can be drawn with no other disease, for there is no other widespread infection so often missed in its early stage, which takes such heavy toll of this omission in later years. It is literally the old Roman decimation : one out of every ten lives must be sacrificed ; there is no certain indication on whom the lot will fall; but in our case amnesty can be claimed by any who have undergone a course of specific treat- ment. In the fight of these general considerations the indications may be stated thus : 1. Before symptoms occur ; where we must at once distinguish between {A) Non-infected, {B) Where infection has occurred but disease has not manifested itself. {A) Before infection has occurred would seem to be an ideal time for immunisation against tuberculosis. Meissen, in fact, in classifying tubercular patients allotted a special division to “prophylactics,” those who were dis- posed to the disease by nature or inheritance without having actually been infected, e.g. the children of tubercular parents.
