vi PREFACE. 



in the minds of the student and the physician, will make it easier for the former to 

 learn his anatomy and for the latter to remember and apply it. 



Dr. White desires to acknowledge fully his obligations to the existing treatises 

 on applied anatomy and to the various text-books and encyclopedias on surgery and 

 medicine from which many valuable suggestions were gathered. To Drs. Gwilym 

 G. Da\-is and T. Turner Thomas, his thanks are due for a careful search for possible 

 errors, for friendly criticism, and for help in the selection of illustrations. 



The illustrations for the anatomy — a matter of fundamental importance in a work 

 of this character — have received most conscientious attention. The determination to 

 produce a series of original drawings that should faithfully record the dissections and 

 preparations as they actually appear, and not as diagrammatic figures, has involved 

 an expenditure of time and painstaking effort that only those having experience with 

 similar tasks can appreciate. When it is stated that considerably more than two 

 thousand original drawings have been made in the preparation of the figures illus- 

 trating the work, some conception will be had of the magnitude of this feature. 



In the completion of this labor the editor has been most fortunate in having 

 the assistance of Dr. John C. Heisler, to whose skill and tireless enthusiasm he is 

 indebted for the admirable dissections from which most of the illustrations of the 

 muscles, blood-vessels, nerves, perineum and inguinal region were drawn, as well as 

 for many suggestions for and revision of the drawings themselves. Professor Gwilym 

 G. Davis has also rendered valuable assistance in supplying the dissections for the 

 drawings relating to the Practical Considerations, as well as in supervising that 

 portion of the artist's work. 



In addition to the numerous dissections and preparations made especially for the 

 illustrations, advantage has been taken of the rich collections in the museums of the 

 Medical Department of the University of Pennsylvania, of the Harvard Medical 

 School and of the Wistar Institute of Anatomy, which were kindly placed at the 

 editor's service. 



Records of the dissections, in many cases life size, were made in water colors 

 chiefly by Mr. Hermann Faber, whose renditions combine faithful drawing with 

 artistic feeling to a degree unusual in such subjects. The records not made by the 

 last-named artist are from the brush of Mr. Ludwig E. Faber. The translations 

 of the colored records into black and white, from which the final blocks have been 

 made, as well as the original drawings of the bones and of the organs, have been 

 made by Mr. Erwin F. Faber. To the conscientious and tireless efforts of this artist 

 are due the technical beauty that distinguish these illustrations. Mr. J. H. Emerton 

 drew the joints, as well as some figures relating to the gastro-pulmonary system, from 

 dissections and sections supplied by Professor Dwight. 



The numerous illustrations representing the histological and embryological de- 

 tails throughout the work, and in addition the sections of the brain-stem under low 

 magnification, are by Mr. Louis Schmidt. In all cases sketches with the camera 

 lucida or projection lantern or photographs have been the basis of these drawings, 

 the details being faithfully reproduced by close attention to the original specimens 

 under the microscope. 



Notwithstanding the unusually generous allotment of drawings from original 

 dissections and preparations, advantage has also been taken of a number of illus- 

 trations which have appeared in special monographs or in foreign journals or works. 

 With very few exceptions such borrowed illustrations have been redrawn and modi- 

 fied to meet the present requirements, due acknowledgment in all cases being given.
