British Mosses. — At the moment of going to press we have 

 received a copy of Mr. C. P. Hobkirk's " Synopsis of British 

 Mosses," consisting of 196 pages of neatly printed letter-press, 

 bound in cloth. Of its contents we have at present had no oppor- 

 tunity of forming an opinion, but, as the most recent authorities 

 appear to have been consulted, we have no doubt that a closer 

 acquaintance will be as satisfactory as the present casual one. Such 

 a handy volume was much needed by British Bryologists.
