obtained by its use, and their applications to the welfare of man-

biology made him, most fittingly, the first chairman of the 
Charity Organization Society’s Committee on the Prevention 
of Tuberculosis, following the discovery of the bacillus which

In 1909 he represented the New York Academy of Sciences at
