AUTHOR'S PREFACE. 



THE scope of an Epitome of Bacteriology and Microscopy 

 obviously affords little or ^no opportunity for original work, 

 nor indeed would it be desirable to do more than represent 

 the actual status of these cognate sciences. Standard text- 

 books have accordingly been consulted freely. The merit 

 of an Epitome consists in affording a concise and clear 

 presentation of essentials, command of which enables the 

 student to build a sound superstructure of knowledge. The 

 practitioner may also use such ' a. volume to post himself 

 on the main facts/of' Bacteriology and Microscopy, and the 

 technique. The Ifst of questions appended to each chapter 

 will be useful to students in quizzing and reviewing.
