APPOINTED PROFESSOR: STUDIES IN PHILADELPHIA. Ill 



J/y Second Winter in Philadelphia. (Nov. 5, 1803, to 

 March 25, 1804.) There was little to distinguish this from 

 the preceding winter. I attended, as before, the course of 

 chemistry and anatomy, and resumed my private labors 

 with Robert Hare. The familiarity which I had acquired 

 in the preceding year with men and things, enabled me to 

 derive additional advantage, and made me feel more at 

 home. My circle of acquaintance was more extended, 

 quite as much as was consistent with my studies. I was 

 admitted hospitably or socially to some of the most esti- 

 mable families, that of Judge Wilson, son of him of the 

 Revolution ; to Bishop White's, Dr. Strong's, Col. Biddle's, 

 where there were beautiful daughters, (afterwards Mrs. Dr. 

 Chapman and Mrs. Cadwallader.) I have mentioned the 

 Wistars, Bainbridges, and Greens. At Judge Peters's, 

 also, I was acquainted, and at Mrs. Bradford's. I visited 

 also the public institutions, r- the Hospital, the Mint, the 

 Navy Yard, the Water Works, the libraries, manufactories, 

 &c. Philadelphia had then seventy-five or eighty thousand 

 inhabitants ; now it has more than half a million. The 

 present beautiful Washington Square was a Potter's Field, 

 and all was country between it and the Hospital. About 

 this time I was elected a member of the Philosophical So- 

 ciety founded by Franklin, and of course had free access to 

 its library, and to its very intelligent and kind librarian, 

 Mr. John Vaughan, a man of large benevolence. I con- 

 tinued the writing of my lectures, and began to collect ap- 

 paratus, although on a humble scale. 



In March, 1804, after passing a few days in Princeton, I 

 returned to New Haven, and devoted my time to writing 

 lectures. 



To Mr. Silliman's reminiscences, written after the 

 lapse of many years, may be added brief passages 

 from his correspondence daring the period covered 

 by the foregoing chapter.
