BIOGRAPHICAL SKETCH 23 



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:
