IV PREFACE. 



So far as we are aware, this work differs from the manuals above men- 

 tioned in one or more of the following particulars : — 



It assumes no previous anatomical knowledge or experience, yet is rapidly 

 progressive, introducing in succession bones, muscles, viscera, vessels, nerves, 

 brain and organs of sense. 



It is based upon the domestic cat {see § 124). The terms of description 

 and desigiiation apply to all vertebrates (§ 38) ; they are technical (§ 29), 

 and precision and brevity have been especially regarded in their selection. 



The purely descriptive portions are subordinated to the practical and 

 directive. There is a General List of the instruments and materials 

 required for ordinary anatomical work (§ 130), and directions are given 

 for their care. All directions for dissection and manipulation begin with 

 special lists of the instruments and materials required (§ 235). Explicit 

 instructions are given for coarse wjectio7is, for the preparation of hones, and 

 for the use of alcohol as a preservative. 



Certain regions and organs are quite fully discussed, while others are 

 briefly mentioned or omitted altogether (§ 128). Unusual space is given to 

 the viscera (§ 129). The study of the brain includes a consideration of the 

 typical vertebrate brain, descriptions and dissections of the brains of the 

 frog and the Menobranchus, and an approximately complete Descriptive 

 List of the encephalic parts, with Eeferences and Synonyms. 



There are illustrations, and the methods of making the preparations 

 figured are fully described. The abbreviations are of the technical names 

 only, and they are nearly uniform throughout. As far as possible, the 

 technical names are written in full upon the figures. In the explanations 

 of the figures, the technical names and the abbreviations are alphabetically 

 arranged (§33). 



There are numerous Alphabetical Lists, Tables of Synonyms and Tabular 

 Arrangements of names according to the relations of parts (p. xxvi). 



Attention is called to the incompleteness of our information upon cer- 

 tain points. 



There are frequent cross references and numerous definite references to 

 other publications (§2) ; the titles of the works and papers cited (three hun-
