PREFACE. 



THE PURPOSE of this work is to afford to those 

 engaged in the practical study of Histology, plain 

 and intelligible directions for the suitable prepara- 

 tion of the animal tissues ; with the object either 

 of immediate study, or of their preservation as spe- 

 cimens for future reference. The methods recom- 

 mended have all been tested by experience. 



In an introductory chapter an account is given 

 of the several parts of the microscope, and the pur- 

 pose for which they are intended, without entering 

 into an explanation of its optical construction ; and, 

 in an Appendix, instructions w r ill be found for 

 measuring and for delineating microscopic objects. 



Throughout the book descriptions of tissues have 

 been purposely avoided, seeing that these are to be 

 found in systematic works. The order followed is 

 that of "Quain's Anatomy," 8th Edition.
