Dr. Horner, appointed Dr. Leidy his prosector. In 1846 he was chosen 

 Demonstrator of Anatomy in the Franklin ]\Iedical College, but resigned 

 the office at the close of the session, in 1847, resumed his position with Dr. 

 Horner and delivered to his students a private course of lectures on 

 Human Anatomy. 



He indulged himself with a short vacation in July, 184G, and visited his 

 friends, Messrs. Haldemann, at Chickies, Pa. 



While his kinsman, Dr, N. B. Leidy, was Coroner of the County of 

 Philadelphia (1845-48), he acted as Coroner's Physician and received fees 

 for the autopsies he made. 



In the spring of 1848, impaired health induced Prof. Horner to 

 visit Europe. He invited his friend, Dr. Leidy, to be his travel- 

 ing companion. They sailed in April and returned in September. 

 In England, Germany and France they "visited hospitals and anatomical 

 museums, and sought out eminent anatomists and surgeons." Dr. Leidy 

 witnessed in Paris, June 20, some vivisection experiments by Magendie, 

 in his physiological laboratory, which interested him. They "were in 

 Vienna while the revolutionary'' movements were in progress :" and 

 "were also in Paris during the fierce conflicts from 23d to 26th of June ; 

 and during several days afterwards they "witnessed in the hospitals, 

 filled with wounded, every variety of gunshot wound and the modes of 

 treatment pursued."* 



On his return from Europe, in the autumn. Dr. Leidy delivered a course 

 of lectures on Microscopic Anatomy; and in the spring of 1849 began a 

 course on Physiology in the ]\Tedical Institute of Philadelphia, which the 

 condition of his health required him to abandon. f 



He edited Qwain's Human Anatomy, which was published June, 1849, 

 by Lea & Blanchard. 



An interesting event enabled Dr. Leidy to go abroad again under very 

 favorable circumstances. Dr. George B. Wood, who was elected May, 18o0, 

 Professor of the Practice of Medicine in place of Dr. Nathaniel Chapman, 

 resigned, desired to collect in Europe models, casts, preparations, etc., 

 suitable for objective illustration of his future courses of instruction. 

 Aware of the artistic judgment of Dr. Leidy, and of his recently acquired 

 knowledge of localities in which objects adapted to his purpose could be 

 purchased. Dr. Wood easily persuaded him to be his companion and 

 assistant in hunting and selecting desirable specimens. 



Dr. Wood had proved, while Professor of Materia Medlca from October, 

 1835, till May, 1850, tliat placing before his class appropriate objects illus- 

 trative of his subject is superior, more successful than the purely oral and
