US, is permanentl}' arrested, does not enjoy imninnity from 

 future attacks of the disease. 



The lungs of many a patient who has succumbed to an 

 attack of acute tuberculosis exhibit evidences of old scars 

 from which all evidences of active disease have disappeared, 

 leaving nodules of fibrous tissue surrounding little grains of 

 calcareous material. These patients have recovered years 

 ago only to subsequently succumb to an attack of acute 

 miliary tuberculosis, in all probability an entirely fresh 

 infection, though of this we cannot be positive. 



It is for cases such as these, cases which have under 

 proper conditions every chance for the enjoyment of fairly 

 useful lives, that the sanatorium regime has accomplished so 

 much, I do not care whether the open air treatment is 

 carried out in special institutions or not. It is not essential 

 that such should be the case, and the fact is too often lost 

 sight of that it can be as effectively carried out at home. 

 The encouraging results obtained at Sanatoria should more- 

 over induce patients after discharge frojn such institutions to 

 continue the treatment, if even in modified form, throughout 

 their own lives. It is impossible to state when a patient can 

 go back to the old round of life, and, in fact, only by insisting 

 on improved conditions of life in our centres of population 

 shall we be able to diminish appreciably the mortality from 

 Tuberculosis.
