viii EDITOR'S PREFACE TO THE FIFTH EDITION 



In addition to a thorough revision of the various sections, there has also been 

 a rearrangement of a part of the subject matter in the present edition. The Teeth 

 have been transferred from the section on Osteology to the Digestive System. 

 The Tongue and Nose are transferred to the Digestive System and Respiratory 

 System, respectively, excepting those portions forming the organs of Taste and 

 Smell, which have been retained in the section on Special Sense Organs. The 

 Pelvic Outlet has been discontinued as a separate section, the subject matter 

 being divided between Musculature and Clinical and Topographical Anatomy. 

 The Ductless Glands have been included in the section with the Skin and Mam- 

 mar}^ Glands. 



Due credit has been given throughout the book wherever illustrations have 

 been taken, or modified, from other works. Special acknowledgment should be 

 made of our indebtedness to the works of Toldt, Rauber-Kopsch, Poirier and 

 C harpy, Henle and Spalteholz. 



The number of figures in the present edition has been increased about one 

 hundred and sixty and in addition many of the older figures have been improved 

 or replaced. For the generosity of the publishers in this connection, and for the 

 hearty cooperation of the contributors in the revision of the various sections, the 

 editor desires to express his deep indebtedness. Valuable assistance has been 

 rendered by Mr. Walter E. Camp in the reading of proof and preparation of 

 the index.
