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 list of questions appended to each chapter 

 will be useful to students in quizzing and reviewing.
