gone, when we can no longer have a voice in its management, and 

 under theories of administration entirely different from ours, so that 

 it is wise to enforce our own views if we can, but if not, to help along 

 as far as practicable, the views of the dissenters." 



A minute of appreciation and regret was adopted on his declining 

 a reuomination for the Presidency. His executive work in the 

 Academy did not, however, cease. He became a member of the 

 Council almost immediately and he was elected a Curator in 1882. 

 On the death of Dr. Leidy in April 1891, he became Chairman of 

 the Board of Curators, which position he held during the rest of his 

 life. His services as Councillor were invaluable because of his 

 retentive memory ami his accurate knowledge of Academy traditions 

 and history during nearly half a century. 



He served on the Publication Committee from 1872 to 1878 and 

 on the Library Committee from 1873 until his death. 



He was Director of the Conchological Section continuously from 

 1869, the year of its formation, and of the Botanical Section from 

 1876 to 1894. He also served terms as Director of the Biological and 

 Microscopical Section and as Vice- Director of the Mineralogical and 

 Geological Section. Until incapacitated by failing health he was 

 rarely or never absent from the meeting of these bodies while 

 officially connected with them. 



Although he devoted the greater portion of his time to the affairs 

 of the Academy they did not absorb his entire attention. He became 

 a member of the College of Physicians »of Philadelphia in March 

 1836, was Vice-President from May 1875 to May 1879 and President 

 from May 5, 1879 until January, 1883. 



He was elected a member of the American Philosophical Society 

 October 17, 1849. The high appreciation in which he was held by 

 his fellow-members is shown by the fact that he was annually re-elected 

 to the Vice-Presidency of that Society from January, 1885. His 

 services to these societies have been recounted in biographical notices 

 specially prepared for them and need not be dwelt on here. 



The following is a list, probably incomplete, of other societies to 

 which Dr. Ruschenberger belonged, with the dates of his election: 



County Medical Society of Philadelphia, March 24, 1831. 



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