 figure of every known British moth, together with dates of 

 appearance, localities, description, and food of caterpillar. It 

 forms a handsome work for a Ubrary,and will, we should 

 hope, lead many to commence the fascinating study of ento- 

 mology .

 ings. 2 volsc 8vo. Cloth. London, 1874.

 The importance and value of this work may be inferred 

 from the fact that it contains descriptions of 1,294 varieties 

 of British ferns, with 79 colored plates of species and vari- 

 eties, and 909 wood engravings, containing much interesting 

 information. The localities are described, each synonyme

In her present work she has endeavored, and we thiuk 

 most successfuly, to translate the terms and phrases of 

 science into the language of amateurs. Mrs. Gatty's famil- 

 iarity with the plants themselves has enabled her to do this 

 office without falling into the errors to which a mere com- 

 piler in separating from the beaten track would be liable.

 works, but a popular description of the plant, — instructions 

 as to its culture and treatment, — with any interesting infor- 

 mation in connection with it that can bo obtained. . . . We 

 heartily commend this work to all lovers of tlowers.
