PREFACE. 



It is hardly necessary to say to Professor, Teacher, or Student that 

 this Manual should be used daily as a companion to the Lessons, in 

 connection with the ever-faithful microscope. The Manual, bound 

 separately, can be conveniently carried in pocket or portmanteau. 



A Table of Etymons, or Eoots (page vii.), immediately precedes the 

 Classification. This does away the need of defining the names of 

 individuals in the Manual, many of which are compounded from the 

 same etymons ; and thus both time and space are saved. Names of 

 Orders are defined in their proper places. The Table of Signs and 

 Abbreviations (page vi.) includes all that are in modern use.
