difSculty in arranging satisfactory dates, 

 there will be only one Stafford Little lecture 

 this year, instead of the usual two. The lec- 

 ture will be published by the Princeton Uni- 

 versity Press in the Stafford Little lecture 

 series, the former volumes in the series being 

 by Grover Cleveland, Joseph H. Choate, Elihu 

 Root and J. G. Schurman. 



At the Founder's Day celebration of Clark 

 University on February 1 the speaker will be 

 Dr. E. S. Lillie, professor of biology in the 

 university. His subject is " The Relation of 

 Universities to Investigation." 



On the return from his recent journey west, 

 Dr. Ales Hrdlicka, of the U. S. National Mu- 

 seum, lectured, under the auspices of the 

 Archeological Institute, on " The Origin and 

 Antiquity of the American Indian," and on 

 " Evolution of Man in the Light of Eecent 

 Discoveries," at San Diego, Los Angeles, 

 Stanford, Berkeley, San Francisco, Denver, 

 Colorado Springs and Pueblo. 



Professor Clara A. Bliss, of the depart- 

 ment of chemistry of Wells College, is on 

 leave of absence for a second year and is study- 

 ing at Columbia University. Dr. Minnie A. 

 Graham continues as acting professor during 

 Miss Bliss's absence. 



Mr. N. C. ISTelson, of the American Mu- 

 seum of Natural History, has returned from 

 several months' archeological field work in 

 New Mexico, where his work was a continua- 

 tion of that of previous years on the ancient 

 villages of the Tanos, south of Santa Fe. 



According to daily papers Mr. Burt M. Mc- 

 Connell, who was secretary to Stefansson, the 

 explorer, and meteorologist of the Canadian 

 Arctic expedition is seeking to induce either 

 the United States government or private citi- 

 zens to send two hydro-aeroplanes into the far 

 north to search for the explorer, who has not 

 been heard from in over a year. Mr. McCon- 

 nell has returned from Ottawa, where he tried 

 to interest the Naval Service Department in 

 the project. He was told that nothing could 

 be done at this time. The belief in Canada is 

 that Stefansson and his two companions, 

 Anderson and Storkerson, are still alive and 

 doing the work planned. 



The city of Philadelphia, acting on the 

 recommendation of The Franklin Institute, 

 Philadelphia, Pa., has awarded the John Scott 

 legacy medal and premium to Dr. Charles 

 Edward Guillaume, of Sevres, France, for his 

 alloy invar. This alloy contains approximately 

 63.8 per cent, iron and 36.2 per cent, nickel. 

 It is characterized by possessing an extremely 

 small coefficient of linear expansion, about 

 0.0000004 per degree Centigrade. Within the 

 limits of atmospheric temperature change, its 

 expansion is very exactly proportional to the 

 temperature. It has a modulus of elasticity of 

 about two thirds that of steel, and its hard- 

 ness is greater than that of hard brass. Invar 

 has found a wide application in metrology and 

 horology. In the former, it is particularly 

 useful for secondary standards of length, and 

 in the latter it is employed for pendulum 

 rods, compensating devices for torsion pen- 

 dulums and balance wheels correcting the 

 secondary error of temperature in chronom- 

 eters. Dr. Guillaume has done a large amount 

 of research work in connection with iron- 

 nickel alloys, in the course of which he also 

 discovered platinite. 



Professor Lewis Lindsay Dyche, professor 

 of systematic zoology and taxidermy and cura- 

 tor of birds and mammals in the University 

 of Kansas, died on January 20, at the age of 

 fifty-eight years. 



Dr. Dudley Peter Allen, professor of prin- 

 ciples of surgery in the medical department of 

 Western Eeserve University, Cleveland, for 

 many years, and later emeritus professor, died 

 on January 6, at the age of sixty-two years. 



Mr. Thomas Bryant, a distinguished British 

 surgeon, has died at the age of eighty-six 

 years. He retired from the surgical staff of 

 Guy's Hospital in 1888, delivered the Hun- 

 terian oration in 1893 and served as president 

 of the Eoyal College of Surgeons of England 

 from 1896 to 1899. 



Surgeon-General William Henbt Mo- 

 Namara, of the British army, died on January 

 9, at the age of seventy years. 



The death is announced, at seventy-one 

 years of age, of Lieut.-Col. D. D. Cunningham,
