Ruschenberger.] i-l'± [Nov. 6, 



fessor of General Chemistry in tlie Franklin Institute, and re- 

 ceived a vote of thanks for his services when he resigned, Octo- 

 ber 20, 1847. In conjunction with his brother Robert, he com- 

 piled from the works of Dr. Edward Turner and. Dr. William 

 Gregory, a volume on inorganic and organic chemistry, designed 

 to be a text-book which was published in 1 846. These many 

 occupations yielded him a modest income. 



In April, 1846, he was chosen a member of the American 

 Philosophical Society. 



In 1847, in the forty-sixth year of his age, he succeeded Dr. 

 Robert Hare as Professor of Chemistry in the University of 

 Pennsylvania. He was a representative of the Franklin Medi- 

 cal College (in which he was at the time Professor of Chem- 

 istry), in the National Medical Convention, assembled in Phila- 

 delphia, May 5, 1847. This convention then became the Amer- 

 ican Medical Association, which is still prosperous. 



In October of the same year, he was elected a member of the 

 Academy of Natural Sciences of Philadelphia. He was one of 

 the representatives of the Univers^ of Pennsylvania in the 

 National Convention for the revision of the Pharmacopoeia of the 

 United States, in 1850. 



He was never robust. His frame was light and elastic. In 

 latter years his constitution was considered to be delicate. At 

 times he suffered from nervous exhaustion and defective nutri- 

 tion, ascribable to long and incessant labor. An attack of 

 albuminuria closed his life, June 15, 1853, in the fifty-first year 

 of his age. He left his widow, who died in 1882, with their two 

 sons and a daughter. 



He was an eminently efficient, interesting and popular teacher. 

 "Disinterested and generous in his relations with the world, 

 mild and conciliating in deportment, open and affable when ap- 

 proached, urbane to every one, his virtues shone conspicuously 

 within the circle of his friends."* 



William Barton Rogers, the second child of his parents, was 

 born in Philadelphia, December 7, 1804.f
