1887. Aa Account of the Institution and Progress of the College of Phy- 

 sicians of Philadelphia during 100 years. (308 pages.) 



This list, however incomplete, is sufficient to reveal Dr. Ruschenber- 

 ger's profound sympathy with the progress and the popularization of sci- 

 entific knowledge in many fields. He was also during the whole of his 

 life an active participant in associations for the collection and dissemina- 

 tion of knowledge, and for the organization of scientific work and work- 

 ers. The following list of those to which he belonged is probably only 

 partial. I add the dates of his election to them, when known to me. 



The Medical Society of Philadelphia, March 24. 1831. 



The Academy of Natural Sciences, Philadelphia, May 29, 1832. 



The United States Naval Lyceum, New York, February 1, 1836. 



The College of Pliysicians of Philadelphia, March 10, 1839. 



College of Physicians and Surgeons, New York, February 22, 1815. 



American Institute, New York, June 13, 1845. 



Pennsylvania Horticultural Society, March 16, 18S6. 



Pennsylvania Zoological Society, October 13, 1887. 



Philadelphia College of Pharmacy (Honorary), March 27, 1893. 



The Historical Society of Pennsylvania. 



The Franklin Institute. 



He was also a member of the Military Order of the Loyal Legion of the 

 United States, to which he was elected October 20, 188!). 



Of several of these associations he was a conspicuously energetic mem- 

 ber and held in them high official positions. From 1839 to 1881 he was 

 President of the Academy of Natural Sciences, and occupied the same 

 office in the College of Physicians from 1889 to 1883. Up to the end of 

 his life he continued his interest and his activity in these two societies, 

 the details of which I need not enter upon, as they will doubtless be given 

 in the pages of their proceedings. 



The records of the American Philosophical Society show that he was 

 elected to its membership on October 19, 1819 ; and to its Vice-Presi- 

 dency, January 2, 1885, a position to which he was annually reelected 

 until his death. 



So far as I have ascertained, he did not publish in its Transactions or 

 Proceedings any papers of a scientific character ; but he was faithful in 

 preparing and reading a number of obituary notices which had been 

 assigned him. The following is a list of such : 



Dr. Robert Bridges, Proc, xxi. 



Dr. Robert E. Rogers, Proc, xxiii. 



Dr. Gouverneur Emerson, I^oc, xxix. 



Dr. Joseph Leidy, Proc, xxx. 



Mr. William B. Rogers, Proc, xxxi. 



Dr. William V. Keating, Proc, xxxiii. 



He was regular in his attendance at the meetings of the Society up to a 

 recent period, when his increasing infirmities rendered it imprudent for 

 him to expose himself to the night air.
