PREFACE. 



HENRY GRAY'S Anatomy, both in the original and its many succeeding 

 editions, has long been held in high esteem as a thoroughly practical treatise 

 on the subject for the medical student. In the present revision the editor 

 has endeavored to adhere to the plan as much as possible, supplying such 

 facts and views as the advances in the science of anatomy render it necessary 

 to incorporate. At the same time, he has endeavored to curtail descriptions 

 of undue length, and to clarify any obscure or ambiguous passages in the text; 

 so that the essentials are here embodied into a fairly complete account of 

 the structures of the human body and their development. It has also been 

 the editor's aim to achieve the utmost degree of uniformity in the mode of 

 treatment throughout the work. 



The title Surgical Anatomy has been replaced with the broader term Applied 

 Anatomy, and under this heading many important medical considerations are 

 now discussed. In the use of descriptive terms concerning which widely 

 different opinions prevail, the editor has sought to take a middle course, 

 employing such designations as seem sanctioned by their usage in current 

 medical literature. 



Many illustrations have been added, largely from original drawings and 

 preparations, and some from standard works. 



The editor is gratefully indebted to his assistants, Dr. Howard Dehoney, 

 Demonstrator of Anatomy, and Dr. Henry E. Radasch, Associate in Histology 

 and Embryology, and Demonstrator of Visceral Anatomy; and also to Mr. 

 Edmond J. O'Donnell, of Albany, for valuable aid in the preparation of 

 this revision. The editor also wishes to thank Mr. William A. Hassett, of 

 Lea & Febiger, for indexing the book, for seeing it through the press, and 

 for the valuable aid he has ungrudgingly given.
