and the following winter had charge of the laboratory work in 
botany of the Harvard Annex. In 1883-1884 she went abroad 
and studied for two years at Strasburg under Prof. Wigand and 
one year at Ziirich, where on July 23d, 1886, she received her de- 
gree of Doctor of Philosophy, having been one of the earliest of 
American women to whom this honor was accorded. On her re- 
turn to America she held a position at Bryn Mawr for two years 
as associate in botany to Prof. E. B. Wilson, who was then pro- 
fessor of biology at that institution. She resigned this position 
because: it was not congenial to her, and during the following 
winter was associated with Prof. W. P. Wilson at the University 
of Pennsylvania in developing its botanical laboratory. 
In the spring of 1889 she was appointed instructor in botany 
at Barnard College, and spent the summer abroad studying with 
Prof. Schwendener, at Berlin, and purchasing microscopes, charts, 
models and books for the new laboratory, the funds for the equip- 
ment of which were supplied from private subscriptions by mem- 
bers of the Torrey Botanical Club. She also spent her summer 
vacations abroad in 1893, 1894, and 1896, and always came back 
with renewed energy and zeal, as well as stores of books and 
fresh knowledge. 
Her department grew rapidly in popularity and in numbers, 
and it soon became necessary to secure the assistance of Miss 
Effie Southworth, now Mrs. Volney M. Spalding, and later of 
Miss Jean Howell. The collections for the laboratory were first 
begun with the herbarium of Elizabeth G. Knight as a nucleus, 
and subsequently that of Dr. Thomas Morong was added by pur- 
chase, also with a fund raised by private subscription among the © 
members of the Torrey Botanical Club. A fellowship in botany — 
was also endowed by Mrs. Esther Herrman, one of our members. 
The laboratory soon outgrew its cramped accommodation on 
the top floor of 343 Madison avenue and in 1895 it was moved to 
the top floor of No. 518 Fifth avenue. In 1896 Dr. Gregory was 
appointed full Professor of Botany and Dr. Herbert M. Richards 
was called to assist her. Together they had planned the ygaed 
courses and laboratories in Brinckerhoff Hall, but Dr. Gregory did 
Not live to see them completed, dying on April 21, 1897, just as the ie 
arrangements for moving her residence and laboratory had — .
