Mathematical Prize; in 1909 and 1910. the Pell 

 Medal for the highest rank in all subjects; 

 and in 1910 and 1911, the Kenyon Prize for 

 Distinction in Pure and Applied Mathematics. 

 He pursued his graduate studies at Columbia 

 University, where he took the degree of mast«r 

 of arts in 1912 and doctor of philosophy in 

 1913. His thesis was entitled " Projective 

 Differential Geometry of Triple Systems of 

 Surfaces," and was a remarkable achievement, 

 for he had, unaided, made himself master of 

 this new field of geometry by independent 

 study and added to it an important contribu- 

 tion. He was a member of the Phi Beta 

 Kappa and Sigma Xi societies. 



Dr. Green returned to his college the follow- 

 ing year as instructor in mathematics. In 

 1914 he was apjwinted to an instructorship at 

 Harvard, and in 1916 became a member of the 

 faculty. Clear, interesting, vivacious, he im- 

 parted to his hearers an imderstanding of the 

 subjects treated which served as a firm foun- 

 dation for future study. In research he was 

 exceedingly productive, and, brief as was the 

 span accorded him for his scientific labors, 

 he had by a notable series of memoirs con- 

 tributed largely to the present development of 

 his special field of projective differential 

 geometry. 



His appreciation of music was extraordinary. 

 Although he had never had formal instruction, 

 he had made himself a skilled pianist, and had 

 sought expression in original comjwsiton. 



His disposition was genial. He was emo- 

 tional and sensitive, and at the same time 

 sympathetic and unselfish. For such a na- 

 ture, the craving for the harmony of a homo- 

 geneous civilization with its uniform ethical 

 ideals and the mutual understanding of its 

 members must have been intense. Green 

 found himself a member of two civilizations, 

 and he was not spared the pain of incessant 

 clashes of their ideals and habits of thought. 

 But the fineness of his spirit and the noble- 

 ness of his character were such that, in the 

 turmoil, he remained serene and grew in 

 strength of mind and soul. High ambition 

 and untiring energy, combined with great in- 

 tellectual gifts, and a fine sense of duty toward 



his fellowmen, were the basis of his success. 

 An attack of influenza was followed by 

 pneumonia, and he died at the Stillman In- 

 firmary on January 24, 1919. The depart- 

 ment lost in him a faithful fellow-worker and 

 friend; the faculty, a teacher of imusual 

 power, and a scientist of high achievement 

 and higher promise.

INTER-ALLIED COOPERATION IN CHEMISTRY' 



Professor Movreu presided over the recent 

 conference in Paris, and among his French 

 colleiigues were Professors Haller, Behal and 

 Matignon, 2iIM. Kestner, Poulenc, Marquis 

 and Gerard. The British delegates were Pro- 

 fessors Louis, Sir William Pope, Messrs. 

 Chaston Chapman, W. F. Eeid. E. Thompson 

 and S. Main. America was represented by 

 Mr. Henry Wigglesworth, Lieutenant-Colonels 

 Bartow. Norris and Zanetti, Dr. Cottrell and 

 Major Keyes; Italy by Senator Paterno, Drs. 

 Pomilio, Giordani and Parodi-Delfino ; and 

 Belgium by MM. Chavanne and Crismer. 



It was unanimously decided to form an 

 Inter-Allicd Federal Coimcil of not more than 

 six representatives of each of the countries 

 mentioned above, the members to hold office 

 for three years, one third to retire annually 

 and be eligible for reelection. The executive 

 body is to consist of a president, a vice-presi- 

 dent, and a general secretary. Mr. Jean 

 Gerard will provisionally act as the secretary. 

 In addition to the council a consultative com- 

 mittee will be formed, consisting of as many 

 sections as may be necessary to secure the 

 complete representation of pure and applied 

 chemistry. The objects of the confederation 

 are: To strengthen the bonds of esteem and 

 friendship existing during the war between 

 the Allied peoples; to organize permanent co- 

 operation between the associations of the 

 Allied nations; to coordinate their scientific 

 and technical resources; and to contribute
