vi MOSSES WITH A HAND-LENS 



The arrangement of the families has been sHghtly changed 

 and the glossary has been greatly changed ; all the terms describ- 

 ing characters discernible by the compound microscope alone have 

 been omitted and a number of common botanical terms have been 

 added for the convenience of amateurs. 



My thanks are due Miss Thayer for her careful work in 

 preparing the illustrations not otherwise acknowledged, and to 

 Dr. Evans for suggestions and the use of some of his illustrations 

 of Hepatics. Many of the additional illustrations are from the 

 Bryologia Europea and a smaller number from Sullivant's Icones 

 and Gray's Manual. Miss Alice Crockett has read all proofs. 

 Mrs. Annie Morrill Smith has greatly assisted by the loan of 

 books, specimens, and illustrations.
