The following resolution on the death of 

 Dr. Theodore Janeway, has been adopted by 

 the General Medical Board of the Council of 

 National Defense: 



The general medical board of the advisory com- 

 mission of the Council of National Defense desires 

 to place on record its profound sense of loss in the 

 death of one of its most active and useful mem- 

 bers, Dr. Theodore Janeway, professor of medicine 

 in the Johns Hopkins University, of Baltimore. 

 In this loss it shares with the entire medical pro- 

 fession, from which has been taken one of its chief 

 ornaments. Dr. Janeway has rendered conspicuous 

 service to the country by his devoted and successful 

 efforts in the Surgeon General's ofa.ce in aiding in 

 the selection of the medical personnel of the Army 

 hospitals. He has died as truly in the service of 

 his country as if on the field of battle. 



On Tuesday evening, January 29, a semi- 

 nary in Stimson Hall, Cornell University,

 Mall, for his work in advancing anatomical 

 science, and for the training and encourage- 

 ment he gave to young men and women who 

 are in the medical and teaching professions. 



RoLLiN A. Harris, since 1890 mathematician 

 to the U. S. Coast and Geodetic Survey, died

Professor Charlotte Fitch Roberts, 

 Ph.D., since 1894 head of the department of 

 chemistry at Wellesley College, died in her 

 fifty-eighth year, after a very brief illness, on 

 December 5, 1917. A correspondent writes: 

 " Through earnest and effective teaching she 

 has, through her contact with a very large 

 number of pupils, rendered a real service to 

 chemistry. The loss of her genial companion- 

 ship is keenly felt by a large circle of friends." 



Dr. W. L. Purves, a distinguished English 

 aural surgeon, has died at the age of seventy- 

 five years.
