Returning to Philadelphia, he continued in the practice of 
medicine for a few years. Desiring more leisure time for the 
study of his chosen science, he abandoned medicine and engaged 
in various manufacturing pursuits. On October 29, 1878, he was 
elected a member of the Academy of Natural Sciences, and in 
the same year he connected himself with the Botanical Section of 
that institution. He was faithful in attendance and contributed 
numerous specimens, notes and verbal communications. He was 
an indefatigable collector and made numerous excursions in Penn- | 
sylvania and neighboring States. He made a special study of the 
peculiar flora of the Pine Barrens of New Jersey, in which depart- 
ment he was recognized as an authority. He acceptably filled 
‘ numefous positions of honor and trust in the Academy of Natural 
Sciences, and at the time of his death was a member of the Board 
of Councillors. During the session of the American Association 
for the Advancement of Science, in Philadelphia, in 1884, he was 
elected a member, and he acted as guide to an excursion of visit- 
ing botanists to the pine barren region of New Jersey. 
Only the ardent lovers of nature can understand his feelings on 
that occasion, when the main object was to show, Dr. Asa Gray 
and Mr. Caruthers, President of the Linnean Society, the se- 
cluded Schizea pusilla Pursh. Nor can the joy of those gentle- 
man be expressed when‘their eyes rested on that quaint fern form 
for the first time. 
He was elected to active membership in the Torry Botanical 
Club of New York, January, 1891. Although publishing but 
little on botanical subjects, he corresponded with most of the bo- 
_tanical authorities in America and made numerous exchanges- 
Perhaps his most important labor consisted in inducing the young 
to study botany, and his greatest pleasure seemed to be in impart- 
ing to others, either in the field or in his “den,” a portion of his 
rich store of knowledge. Chiefly with this object in view, he 
founded the Philadelphia Botanical Club, in December, 1892, of 
which he was the President from its organization until the time of 
his decease. 
The fundamental aim of the Club is to study the local flora and 
prepare an herbarium representing the plants found within a 
radius of fifty miles. gee: of the members gratefully remember
