 these lives is almost beyond compute, as is also the cost 

 of caring for such an army of sick persons. Suffering, 

 death, and sorrows have diminished, but there still 

 remains much to be done. 



WORK STILL TO BE DONE. More scientific research 

 to determine many unknown factors on infection and 

 immunity and the final perfection of a cure for tubercu- 

 losis which would be as effective as quinine is for malaria,
