102 DUST AND ITS DANGERS. 



this lesson, first of all, the patient should learn, 

 that he must see to it that all expectoration be 

 destroyed, or else he is constantly running the 

 risk of reinfecting himself, and thus destroying 

 his chances of a victory over the disease, and 

 is, moreover, exposing others to a serious risk 

 of acquiring it. 



The establishment of special sanitariums in 

 the country where consumptives may be intel- 

 ligently cared for is not only of great benefit 

 to the stricken individuals themselves giving 

 them, as a rule, the best chances for recovery, 

 but is of incalculable importance to commu- 

 nities at large, since it removes an important 

 and, as we have seen, often active source of 

 dissemination of the disease. 



It has not seemed to fall within the scope of 

 this little book to give detailed directions as to 

 the most efficient means of destroying infec- 

 tious material in the sick room nor the modes 

 of disinfection of such rooms when the disease 

 has passed, because these are matters which will 

 always be attended to by the physician if he be 

 intelligent and well informed, and must vary 

 more or less with the conditions of each case.
