that of any of the great investigators who 

 had preceded him. 



Throughout these sketches, in a few in- 

 stances, minor collateral facts could not be 

 ascertained or verified, although numer- 

 ous works were searched. In some cases 

 authors disagree as to dates of births and 

 deaths. In such instances the different 

 opinions are stated. A few obscure names 

 have been omitted because of the inability 

 to secure the proper historical data. In 

 the preparation of these sketches the fol- 

 lowing works have been consulted : Mor- 

 ris' "Anatomy," Gray's "Anatomy," Allen's 

 "Anatomy," Mayne's "Lexicon," Baas's 

 "History of Medicine," Foster's "History 

 of Physiology," Richardson's "Disciples of 

 JEsculapius," " The Index Catalogue of the 

 Library of the Surgeon-General's OMce, 

 U. S. A.," and Gould's "Illustrated Medical 

 Dictionary." I am also under obligations 

 to Dr. William Osier and Dr. John Ruh- 

 rah, of Baltimore, Dr. Frank Baker, of 

 Washington, D. C., and Dr. P. Hebert, of 

 Iron Mountain, Mich., for assistance ren- 



dered.
