such sciences as this which so strongly appeal 

 to the practical man of affairs, and the estab- 

 lishment of such institutions as the Rockefeller 

 Institute, the Carnegie Institution, and the vari- 

 ous foundations for the special study of re- 

 stricted fields like tuberculosis will all aid 

 greatly in the development of American sci- 

 ence. 



For a number of years the government has 

 been doing a large amount of bacteriologi- 

 cal work along lines which are primarily 

 of interest to agriculture, but the scope of these 

 studies has been materially broadened within 

 the last few years, through the formation of 

 the Public Health Service in connection with 

 the Marine Hospital Service. Work along 

 these sanitary or hygienic lines will also doubt- 

 less be greatly extended through the medium of 

 State and municipal public health laboratories. 

 The original function of these laboratories was 

 largely of a routine character, but with the 

 development of bacteriology the scope of 

 their activity has been greatly increased, and 

 already a number of them have become strong 

 research centers. The opportunity for coopera- 

 tive effort among a number of institutions 

 carrying on allied work is excellent, and the 

 auspicious beginning made in the diphtheria 

 work of the Massachusetts and Minnesota 

 boards of health augurs well for the advantage 

 to be derived from such joint investigations.
