Ya., and so became a permanent member of the society. At its 

 meeting in New York, 1853, he represented the University of 

 Pennsylvania. He was present when the Association met at 

 Philadelphia, in 1855, and again as a representative of the Uni- 

 versity of Pennsylvania in 1872. At that meeting, in behalf of 

 the profession of Philadelphia, he welcomed the delegates.* 



He was elected Professor of Chemistry in the University of 

 Pennsylvania, August, 1852, in place of his brother James, de- 

 ceased, and Dean of the Medical Faculty in 1856. 



The American edition of Lehmann's great work, Physiological 

 Chemistry, was edited by him and published by Blanchard & 

 Lea, October, 1855.f 



He was chosen a member of the American Philosophical So- 

 ciety July 30, 1855, and elected one of its Council January 7, 

 1859. He was frequently present at the meetings of the So- 

 ciety, often took part in discussions, and served on several com- 

 mittees. 



He was elected a Fellow of the College of Physicians of 

 Philadelphia April 1, 1857, but was rarely present at its meet- 

 ings. At one of them, 1858, he related a case of arsenical 

 poisoning in which he appeared in Court as an expert. The 

 victim had been taking, for some time, subnitrate of bismuth 

 by prescription. He found that a remnant of the same con- 

 tained a small quantity of arsenic, and also that samples of sub- 

 nitrate of bismuth, obtained from ten druggists' shops, were 

 contaminated in like manner, but not sufficiently to render the 

 quantity ordinarily prescribed dangerous. On this testimony 

 the jury acquitted the accused, although circumstances strongly 

 implied his guilt.J Arsenical contamination of the subnitrate 

 of bismuth of the shops had not been previously suspected.
