occasion of a lecture on Pneumatics, at the old hall of the Col- 

 lege of Medicine, in Fourth street below Arch, to the great de- 

 light of his scientific friends. 



Two streams, Philanthropy and Philosophy, ran naturally 

 then through the veins of our departed friend and fellow mem- 

 ber. The story of his life divides itself into these two chapters. 

 His love of knowledge not onl}' attracted him to the room in which 

 we sit, filled with souvenirs of men, whose portraits surround us 

 and represent the highest thinkings of the early days of the 

 nation, — and to the rooms of the Academy of Natural Sciences, 

 of which he became a member in November 1849, — but it attached 

 him to the society of educated citizens whatever might be the 

 special ground of their association ; and of cultivated foreigners 

 who visited our city. His membership in the Historical Societ}' 

 of Pennsylvania commenced as earl}' as January, 1842, and his 

 interest in its proceedings never flagged. 



On the other hand, his warm heart, his sympathy with suf- 

 fering wherever he saw it, his clear comprehension of the duties 

 of society towards its unfortunate classes, working uuder the 

 guidance of an uncommonl^y avcU balanced intellect, gave him 

 an early and advanced position in the ranks of Christian Philan- 

 thropists. It was in 1 845 — he was twenty-nine years old — when 

 he took hold of two of the principal reforms of the age, and 

 it may almost be said that he made one of them his own. 



In October of 1845 he became a Manager of the Pennsylvania 

 Colonization Society ; and was sent as a delegate to the Annual 

 Meetings of the mother Society held at the seat of government 

 in 1853, 1854 and 1855, in which last 3'ear, he wrote, as Chair- 

 man of the Committee, its report of "plans, for taking steps to 

 obtain a completion of the partial exploration by the Govern- 

 ment of the United States of the country lying east of Liberia." 

 In his message of 1852, the President of the United States had 

 jjublished the fact that incipient measures had been taken 

 towards the reconnoisance of the Continent of Africa, east of 

 Liberia, directing Commander Lynch to attach himself to the 

 squadron for that dut3\* Mr. Lynch's report was made to the 

 Secretary of the Navy from Philadelphia, September 5, ISSS.f
