 greatly perplex the student. 



It is not expected that the book will furnish the ex- 

 perienced student with much information; it is written 

 to help the beginner and while it is thought that it will 

 be sufficiently complete for the requirements of all such, 

 we especially hope that it will serve as an introduction 

 to more advanced works, and that the result will be, 

 a clear understanding of the elementary methods, and 

 therefore a much more intelligent use of the advanced 

 books on Histology and Bacteriology. 



It will be noted, that no attempt has been made to 

 introduce descriptive Histology and scarcely any de- 

 scriptive Bacteriology, but that the book is confined to 

 Technique.
