80 Report of the President 



complete, shows how the water supply of the camp is purified, 

 how the waste is disposed of, how the soldiers in the tropics 

 are protected against insect-borne disease and how the sick 

 are cared for in the Red Cross hospitals. The daily dietary 

 of the American soldier is illustrated, and its energy value 

 compared with that of other armies, while a series of actual 

 specimens and diagrams shows how typhoid vaccine is pre- 

 pared and illustrates the striking results obtained by its use. 



One of the most gratifying events of the year has been the 



presentation to the Museum for installation in the Hall of 



_ A P Public Health of a replica in bronze of the famous 



Bust of . 



_ DuBois bust of Pasteur, which we owe to the cour- 



Pcistcur 



tesy of M. Vallery-Radot, the son-in-law of Pasteur, 



Dr. E. Roux, Director of the Pasteur Institute, Paris, and Pro- 

 fessor A. Calmette, Director of the Pasteur Institute at Lille. 

 This bust now occupies a very fitting place at the entrance 

 of our hall. 



The activities of the museum and distributing center for 



living bacteria have continued as heretofore. The laboratory 



_ . , . , has 670 different strains under cultivation. 



Bacteriological _ . ' ■ _ 



During the year ending December 1, 1914, 

 Museum s J ° . . ' y * 



we sent out 3,283 cultures, making a total 



of 7,812 which have been distributed since the opening of the 

 laboratory. Over 300 different institutions in America and 

 Europe are now correspondents of our laboratory, and the 

 importance of the work is greatly increased by the setback 

 which the scientific work in similar institutions in Europe is 

 experiencing. The continuance of the work of the bacterio- 

 logical museum and distributing center during the last six 

 months of the year was made possible by generous gifts from 

 Mr. Felix M. Warburg and Dr. Walter B. James. 



In addition to the preparation of the traveling exhibit circu- 

 lated by the Department of Public Education, the Department 



_ „ y . of Public Health has furnished living 



Extension Work , r , 



TT- , o. t , cultures of non-pathogenic bacteria 

 in the High Schools , , , . f . 



to many of the high schools and 



has supplied these schools with bacteriological culture media 



for their regular class work.
