BIOGRAPHICAL SKETCH

chipate in which I had discovered the interesting yellow dye 
that compared favorably with fustic. 
“At this meeting I made the acquaintance of quite a num¬ 
ber of scientific men and renewed the acquaintance of others 
whom I had met at former meetings. 
“Professor Edward S. Morse of Salem was the president, 
and his delightful geniality never showed to better advantage 
than at this meeting. Professor S. P. Langley, whose labora¬ 
tory I had visited near Pittsburg in ’85, also attended the meet¬ 
ing. I saw a good deal, too, of Dr. Wiley, the chemist of the 
Agricultural Bureau. He was president that year of the chem¬ 
ical section, and he had me preside in his place on one or two 
occasions when he read papers before the section. 
“I saw a great deal of Dr. Wiley the following winter, and 
we talked over many subjects relating to my chemical theory 
of plant classification. He was himself interested in plant 
analysis, as it was a part of the work of the Agricultural Depart¬ 
ment, and his private researches were almost exclusively in that 
field. In my public lectures, given during the winter of ’86 and 
’87, Dr. Wiley came from Washington especially to attend 
them, and assisted me in arranging the diagrams and experi¬ 
ments in the hall before the lectures. 
“That season I gave two lectures before the Franklin Insti¬ 
tute, and I lectured at the Academy of Natural Sciences and at 
the Philadelphia College of Pharmacy to large audiences. In 
the spring of ’87, I gave, in Washington, one of the Saturday 
lectures under the auspices of the Philosophical and Anthropo¬ 
logical and Biological Societies, in the United States National 
Museum. The subject chosen was the chemistry of the higher 
and lower plants, and owing to the courtesy of Dr. Wiley, the 
government greenhouses were placed at my disposal, and a liv¬ 
ing exhibition of plants, from the highest to the lowest, illustrated 
my lecture. Most of the Washington science coterie were pre¬ 
sent, and after the lecture we met at an informal reception.” 
The Philadelphia “Ledger,” in a long and appreciative 
notice of her Monday night lecture on plant chemistry before 
the Franklin Institute, called it “an entertainment altogether 
unique,” and remarked: —
