10 TRANSACTIONS OF THE [OCT. 12, 



Immediately after g-raduation he accepted the position of nig-ht 

 superintendent at Havemeyer & Elder's sugar refinery, but shortly 

 afterwards removed to Deadwood, Dak., where he joined one of his 

 classmates, and together they opened an office as " Minin.g En- 

 gineers, Chemists and Assayers." In the spring of 188G he 

 returned to New York, on account of urgent family reasons and 

 decided not to return, but to devote his time to pure science. He 

 was appointed Honorary Fellow, afterwards Fellow in Geology at 

 Columbia College, and rapidly made himself familiar with the prin- 

 ciples of botany, geology and zoology. Of the latter he made a spe- 

 cialty, and the lectures in this subject at the college during that time 

 were delivered by him. The zoological collection in the School of 

 Mines, particularly the invertebrate part, is largely his creation. He 

 also purchased and presented to the collegea collection of New Eng- 

 land birds consisting of some 1500 specimens, besides miscellaneous 

 material too numerous to mention. 



His work in his chosen field of study was evidently appreciated, 

 for on the 5th of last May he was made tutor in Zoology, and his 

 appointment was practically settled as the future assistant to Prof. 

 Osborn in the new School of Biology. In order to perfect himself 

 in the duties which he expected soon to assume he had obtained 

 leave of absence for a year, intending to start, during the early 

 part of last September, for Germany, to study under Hertwig and 

 Haeckel. 



His loss to Columbia College is already manifest — his loss to 

 science we can only imagine, but the finished and unfinished work 

 which he has left behind him give evidence of acute powers of 

 observation, painstaking study, and a strict regard for trutli in 

 recording of facts — all of which qualities are the essentials of a 

 successful man of science. He held membership in the Torrey 

 Botanical Club, American Institute of Mining Engineers, Linna^an 

 Society, American Ornithologist's Union, American Folk-lore 

 Society, American Association for the Advancement of Science, and 

 International Geological Congress, as well as in this Academy.
