54 A HISTORY OF NATIONAL TUBERCULOSIS ASSOCIATION 



to help bear in mind that tuberculosis is a disease of all people, 

 rich and poor, the educated and uneducated ; that it is not con- 

 fined to climates or races, but that it is universal ; and that every 

 one should be interested in combating it. Even those with no 

 means can help by acquainting themselves with the simple pre- 

 cautions to prevent the disease and by imparting what they know 

 to others who do not know. Personal service is as essential as 

 financial aid in fighting the great white plague. 



Pasteur, to whom the world owes so much as the father of 

 modern preventive and curative medicine, has pointed out our 

 duties in the following words: "En fait de bien a repandre, le 

 devoir ne cesse que la ou le pouvoir manque" (In doing good the 

 duty ceases only when the power fails.)
