A BritisL. Marine Flora is being compiled, Init no date 

 for its appearance has, I have been kindly informed, as 

 yet been fixed by its author. 



The works by Miirra}' and Huuck quoted alcove may be 

 of some help, especially the former, although it treats of 

 foreign as well as liritish marine alga^. It contains a 

 short list of books and atlases of algological interest. 



Vol. I., part 2, of Eiigler and Prantl's " Die Xatiirlichen 

 Pflanzenfamilien," which treats of the algae, is a very 

 useful book to consult. By the aid of this the beginner 

 may often be able to determine the genera.
