264 PROCEEDINGS OF THE ACADEMY OF [April, 



relating to the conduct of the school. The feeling entertained for 

 him by his students was one of personal affection. 



A memoir of his predecessor, prepared for the College of Physi- 

 cians, was published in the Transactions and is a well-expressed 

 appreciation of the work of Dr. Meigs as a teacher and of the value 

 of his contributions to anthropological science. 



While acting as demonstrator to Dr. Meigs, he was elected in 1878 

 to the Professorship of Physiology in the Pennsylvania College of 

 Dental Surgery. He retained the position until 18S5, when, desirous 

 of giving undivided attention to his educational work in Jefferson 

 College, he resigned. Here, as elsewhere, the force and originality 

 of his teaching secured the attention and interest of his class, and 

 his resignation was regarded as inflicting a loss on the institution. 



Europe was again visited in 1882 and 1887. During a stay in Paris 

 in 1899, he was presented to the Academy of Sciences and he made 

 a communication before the Society of Biology on the placentation 

 of the elephant. An abstract of his remarks was published in the 

 Comptes Rendus of the Society, where also appeared, in 1903, some 

 notes on the placentation of mammals in general. 



His attention while in Paris was by no means confined to scientific 

 interests, the vast storehouses of literature and art so liberally adminis- 

 tered there for the benefit of the public receiving a full share of his 

 attention. He visits the Bibliotheque Nationale to look at one of the 

 two complete copies in existence of the Christ ianismi Restitutio of 

 Michael Servetus. It is easy to believe that he was more attracted 

 by the rarity of the volume than by its contents. He is also shown 

 Charlemagne's Bible and those of most of the kings of France; the 

 memoirs of Louis XI Y, written by himself in the intervals of his 

 intrigues; the Bible of Catherine de Medicis bound at a cost of 60,000 

 francs ; the great Mazarin Bible; the autographs of Montaigne, Rabelais, 

 Moliere (the only one in existence); the first books of travel printed; 

 lots of Caxtons, letters of Columbus, Vespucci, Cortez, Pizarro, and 

 hundreds of other treasures in which he revels. He spent another 

 pleasant day at the Observatory with Simon Newcomb, when, because 

 of the presence of the distinguished American astronomer, the resources 

 of the establishment were courteously displayed. 



The History of the Discovery of the Circulation of the Blood was 

 published in 1884. The essay was given as a lecture in Jefferson 

 College the year before. It makes a small volume of fifty-six pages, 

 but it is, from a literary point of view, the author's most satisfactory 

 work, showing erudition, thoroughness of research and clearness of
