14 author's preface. 



In order to insure the accuracy of the illustrations, all of the preparations were photographed 

 and the photograph was made exactly the same size as the intended illustration, lenses of the 

 longest possible focal length being employed to avoid perspective distortion.* In the great 

 majority of the illustrations photographs were employed as the basis of the drawings; Figs. 

 167 to 171 are direct reproductions of photographs, and Figs. 178 and 181 were made from 

 photographs which had been touched up. Only a few illustrations are diagrammatic, and in 

 such instances it has been so stated in the titles. 



The illustrations produced by the half-tone method have been made much clearer by the 

 use of a number of colors. A buff color has been employed for the bones in the pictures of the 

 joints and of the muscles, and various colors have been used for the different bones of the skull 

 and in the topographic views of the cranium. f No illustration has been omitted which would 

 make the relations of the parts more readily understood. Microscopic and topographic anatomy 

 have been disregarded to a certain extent, although enough has been given to serve as an outline 

 for the subsequent volumes, which will be more topographic than descriptive in character. The 

 parts have been designated according to the Basel nomenclature. 



The original drawings for this Atlas were executed by Messrs. K. Hajek and A. Schmitson.J 

 The former gentleman, who will also furnish the illustrations for the subsequent volumes, has 

 performed his difficult task with such special aptitude and cleverness that the remaining volumes 

 promise to be even better and to exhibit still greater uniformity in the method of production. 



A number of the specimens from which the illustrations were made are in the collection of 

 the Anatomical Institute (Wurzburg), and I take this occasion to express my special thanks 

 to Professor Stohr for his permission to employ them in this work. The majority of the joint 

 preparations, all of the muscle dissections and some of the bones, I have myself prepared for 

 the Atlas. In addition to the photographed specimens, other dissections have been made and 

 compared, so that every illustration in the book has an individual character, with the exception 

 that marked anomalies have been corrected. The muscles have been given a bright red color 

 such as they exhibit in a fresh body after they have been exposed for a short time, although 

 less intense tones have been selected than those of the natural muscular and fatty tissues. 



The publishers have spared nothing to make the illustrations excel those of all other works 

 in character and to equal if not exceed those of the majority in number. In spite of this, how- 

 ever, the price of the work is much lower than that of most other atlases.

tions were necessary they have hern distributed over several figures. In some instances explanatory outline etchings have 

 been appended with the designations inscribed thereon. In the lithographic plates the inscriptions have been made by 

 a second impression. 



* In a few cases in whi< h perspective distortion was feared even when lenses of the longest focal lengths were em- 

 ployed, the subject was photographed to one-half the size of the desired illustration and the photograph was subsequently 

 enlarged. 



f In carrying out this idea the same bone has always been represented by the same color; for example, the palate bone 

 in blue, the ethmoid in orange. 



J About ten of the illustrations in the Atlas were sketched by W. Freytag, drawing master in the University, and 

 subsequently completed by Mr. Hajek.
