a medical student, and was fortunate in having the very eminent Dr. 

 I'hysic as his private preceptor in the medical profession. Already 

 the medical department of the University of Pennsylvania had at- 

 tained pre-eminence among the institutions of the United States, and 

 his opportunities for acquiring knowledge were of a very high order. 

 He graduated in the spring of 1880, but his thirst for information in 

 the structure of the great world around him, impelled him to enter on 

 a still wider course of study. Europe was then far more advanced 

 than America in the sciences, and he determined to avail himself of 

 whatever advantages he could enjoy beyond the Atlantic. He accord- 

 ingly embarked, and arrived in Paris ten days before the Revolution 

 of July, 1830. He there listened to the lectures of Cuvier and other 

 Professors who gave the Univei'sijiy of Paris its celebrity. He was a 

 freqiiont visitor to the Jardin des Plantes, and besides his medical 

 studies he paid much attention to Botany, Zoology and Geology. The 

 next summer, after his arrival in Europe, he made a tour on foot to 

 form a practical acquaintance with the natural history of that part of 

 the world. He was accompanied by a young friend and fellow-student. 

 Dr. Caspar Pinnock of the vicinity of Philadelphia, and with their 

 knapsacks on their backs and their geological hammers in their hands, 

 they travelled extensively through France and Switzerland. During 

 the period of his residence in Europe he also visited England and Ire- 

 land, and attended a course of medical lectures in Dublin. After 

 remaining two years beyond the Atlantic, he returned again to his 

 native city, Philadelphia. 



We now behold him fairly furnished by a variety of studies for a 

 life of scientific usefulness. His apprenticeship in pharmacy had 

 yielded its fruits of Chemistry, Natural Philosophy, and Minerology. 

 His attendance on the lectures of the Universities in Philadelphia, Paris, 

 and Dublin, are now over, and they have given him grand and glorious 

 views of the Material Universe. His geological tours in America and 

 Europe have made him practically acquainted with the sti'ucture of 

 our planet. Henceforth, independently of Schools and Universities, he 

 pursues his way deeply and more deejtly in the mysteries of creation. 



He was qualified, and had received his diplomas, for the practice of 

 medicine, but, except as a matter of benevolence, his medical practice 

 was neglected for scientific investi^-ation. The Asiatic cholera had 

 raged in Europe while he was there, and he had thoroughly and prac- 

 tically studied its mode of treatment ; and as that epidemic reached 

 America in the same season of his own arrival, his services as a physi-
