92 Report of the President 



tions have availed themselves of our service during the year, 

 making 492 in all. 



The Department has continued to cooperate with the De- 

 partment of Public Education of the Museum in the prepara- 

 tion of material for the use of New York City 

 Extension schools, illustrating the methods of bacteriology 

 and the control of insect-borne diseases. Classes 

 from medical schools, schools of nursing, normal schools and 

 colleges are visiting the Hall of Public Health in increasing 

 numbers, and lectures have been given to many such classes 

 during the year. 



The year has been a fruitful one in research. The staff has 

 cooperated in a systematic study of the typhoid and allied 

 groups of bacteria, the results of which are now 

 being prepared for publication. The Curator has 

 prepared for the Society of American Bacteriologists a general 

 review of the wider problems of bacterial classification and a 

 new outline of families and genera which was presented at the 

 meeting of the Society in December. Dr. Kligler has pub- 

 lished several important contributions to bacterial classification 

 and physiology, and Dr. Hull has nearly completed an exhaus- 

 tive statistical study of the recent outbreak of infant paralysis 

 in comparison with those of earlier years in this and other 

 countries. 



Dr. I. J. Kligler, after four years of untiring service, re- 

 signed in October to accept an important position in the Rocke- 

 feller Institute for Medical Research. The successful 

 organization of the Museum of Living Bacteria is due 

 chiefly to Dr. Kligler, and his enthusiasm, knowledge and in- 

 sight have been a constant source of inspiration to all who have 

 been associated with him. 



Mr. L. V. Coleman has also left the Department, to take a 

 Fellowship at Yale University. During the year that he was 

 connected with the Museum, he displayed a real genius for 

 the art of exhibition, and he has contributed materially to the 

 development of the Hall of Public Health.
