ones ; and perhaps no portion of his investigations were 
more acceptable to his brethren, or marked with more 
benefit to the profession, than this series of unpretending 
communications. 
Two of his contributions relate to Boullay's filter, and 
method of displacement, and we believe that he was the 
first on this side of the Atlantic to comment on this valua- 
ble improvement in pharmaceutical manipulation. 
His other papers embrace a variety of subjects, generally 
having a practical tendency, often original, though frequently 
composed of commentations on the labours of French writers, 
with the language of which he was familiar; an accom- 
plishment that enabled him on very many occasions to lend 
his aid in the way of translations. 
In 1840 he became a member of the Philadelphia College 
of Pharmacy, and shortly afterwards was chosen by the 
committee of the College, then engaged in revising the 
Pharmacopoeia, as one of their three assistants, which duty 
he performed in a creditable manner. About this period 
he was elected a member of the Board of Trustees, of which 
body he continued a member until his death. 
The character of his mind, though not marked with 
striking originality, was particularly well suited for his pro- 
fession ; and in viewing subjects he was influenced more 
by the practical and useful, than by any abstract scientific 
interest they might possess. His acquaintance with English 
literature and general history was of no mean extent, and 
his familiarity with the French language gave him access 
to the writers of that country, of which he extensively 
availed himself. 
His mild and courteous demeanour marked him esa 
gentleman, and in his intercourse with society the impres- 
sions left on the minds of his associates, were altogether in 
favour of the goodness of his heart. May we who are left 
emulate his virtues, and endeavour by increased industry to 
fill up the professional hiatus occasioned by his early and 
lamented death. W. P. Jr.
