10 TRANSACTIONS OF THE [ocr. 12, 
Immediately after graduation he accepted the position of night 
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 ‘“ Mining En- 
gineers, Chemists and Assayers.” In the spring of 1886 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 college a 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 Zodlogy, 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 obiained 
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 truth 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, Linnean 
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. 
The titles of his principal published papers are: 
Plant Notes from Termiscouata Co., Canada. (Bull. T. B. C., 
Nov. 1887.) 
The Eruption of Krakatoa in 1883. (8S. of M. Quart., Jan. 1889.)

(Bully lB. C., Feb. 1890.)

March, 1891.) 
In addition to these there are various minor notes and memoranda 
published mainly in the Bulletin of the Torrey Botanical Club and 
the American Naturalist.
