APPENDIX. 



PRACTICAL DIRECTIONS. 



The following appendix on the dissection and study of tlie cat 

 is not intended as a general treatise on methods of preservation and 

 dissection, but attempts only to give the application of well-known 

 methods to the dissection and study of the particular animal with 

 which the book deals. General methods which are referred to but 

 not described must be looked up, if unfamiliar, in the manuals of 

 general methods. 



yli'i/s /o Disseciio7i and Study of the Cat. — A copy of jayne's 

 " Mammalian Anatomy" should be in the laboratory for reference. 

 Only the volume on the Bones of the Cat has been issued thus far. 



Wilder and Gage's "Anatomical Technology" will be found 

 very useful for methods of work. 



The plates of Strauss-Durckheim's "Anatomic du Chat" are 

 exceedingly valuable for the bones and muscles, and should be in 

 the laboratory if possible. Outline reproductions of these plates 

 have been published by 11. S. Williams (G. P. Putnam's Sons, 

 New York, 1875). The use of both the original plates and the re- 

 productions is made difTicult by the antiquated nomenclature used 

 for the structures figured. 



Alethod of Use 0/ the Present Directions. — Except in the case of 

 the Bones, the order of study of the structures is usually not the 

 same as the order in which they are described. This is of course 

 due to practical difhculties in dissection. The present directions 

 give the order of study, or at least the order of dissection; of course 

 after dissection the structures can be reviewed in the logical order 

 given in the descriptions. But in the first study and dissection, the 

 student is to use these directions for the order ofivork, while using 

 the body of the book for the descriptions. It will be necessary 

 therefore to keep the book opened in two places, — one in the 

 appendix, for the directions; one in the body of the book, for 

 descriptions. In studying the muscles, for example, the student will 

 follow the order of dissection given in the appendix, but as every 

 muscle is dissected he will find, confirm, and study the description of 

 that muscle given in the body of the book. Other organs are 

 studied in a similar manner.
