SCIENCE. 



971 



being made for celebrating on April 6, 1901, 

 the 25th anniversary of the foundation of the 

 Society. 



Professor E. Dana Durand, of Leland Stan- 

 ford University, has been appointed secretary 

 of the TJ. S. Industrial Commission. 



Mb. Mbkeitt Lyndon Fernald, assistant 

 in the Gray Herbarium of Harvard University, 

 has recently been elected a fellow of the Amer- 

 ican Academy of Arts and Sciences. 



Dr. Wesley Mills, professor of physiol- 

 ogy at McGill University, spent last year in 

 Europe and was the guest of Professors His, 

 Held and Flechsig, more especially while con- 

 ducting researches on the nervous system. He 

 returned in the latter part of September, and is 

 devoting himself largely to the problem of the 

 equipment of the new laboratory and the re- 

 arrangement of the courses in his subject. 



It is rumored that Mr. J. H. H. Teall will 

 shortly succeed Sir Archibald Geikie as direc- 

 tor of the Geological Survey of Great Britain 

 and Ireland, and that Mr. C. Lapworth will 

 be appointed to the chair of geology in Univer- 

 sity College, London, vacant by the resignation 

 of Professor T. G. Bonney. 



Nature reports that the government of Ja- 

 maica is obliged to retrench in the work of the 

 Museum, necessitating the discharge of the cu- 

 rator. Dr. J. E. Duerden. Dr. Duerden has 

 carried on important investigations in marine 

 zoology, and the cessation of his work will cause 

 regret amongst all zoologists. 



A GENERAL Committee is being formed to ar- 

 range a memorial of the late Professor Henry 

 Sidgwick of Cambridge University. It may be 

 remembered that Professor Sidgwick several 

 years ago requested that his salary as Knight- 

 bridge professor of moral philosophy be reduced 

 from £700 to £500 per annum, the reduction to 

 continue until 1902. Mrs. Sidgwick has, in 

 accordance with Professor Sidgwick's wish, 

 contributed this year £200 and will do the same 

 next year to carry out Professor Sidgwick's 

 subscription for the benefit of the University. 



We regret to record the death of Professor 

 Marshall Henshaw, formerly professor of physics 

 and astronomy at Rutgers College and later 



lecturer on physics at Amherst College, and of 

 Dr. S. Hoepfuer, consulting engineer and chem- 

 ist, of Hamilton, Ont. 



The Samuel D. Gross prize of $1,000, of the 

 Philadelphia Academy of Surgery, was not 

 awarded this year, as suitable contributions 

 were not received, and the time has been ex- 

 tended to October 1, 1901. The prize is 

 awarded every five years to the writer of the 

 best original essay, not exceeding 150 printed 

 pages, octavo, in length, illustrative of some 

 subject in surgical pathology or surgical prac- 

 tice, founded upon original investigations, the 

 candidates for the prize to be American citizens. 



In connection with the Geological Survey of 

 Iowa, now in progress. Professor Macbride is 

 attempting to present to the people of the State 

 an accurate account of their all too slender 

 forest resources. Appended to the report 

 of the geology of each county, appears an 

 annotated list of the arboreal species of plants 

 found within the same limits, with special 

 reference to the economic value of the several 

 species and recommendations for the aid of 

 farmers and others who may attempt tree- 

 planting on an extensive scale. The latest 

 issues are reports on Osceola, Dickinson and 

 Dubuque Counties.
