NOTICES TO CORRESPONDENTS. 



Am. communications relative to advertisements, post-office 

 orders, and orders for the supply of this Journal, should be 

 addressed to the Publisher. All contributions, books, 

 and pamphlets for the Editor should be sent to 192, 

 Piccadilly, London, W. To avoid disappointment, contri- 

 butions should not be received later than the 15th of each 

 month. No notice whatever run be taken of communica- 

 tions which do not contain the name and address of t/ie 

 writer, not necessarily for publication, if desired to be with- 

 held. We do not undertake to answer any queries not 

 specially connected with Natural History, in accordance 

 with our acceptance of that term ; nor can we answer 

 queries which might be solved by the correspondent by an 

 appeal to any elementary book on the subject. We are 

 always prepared to accept queries of a critical nature, and 

 to publish the replies, provided some of our readers, besides 

 the querist, are likely to be interested In them. 



W. W.— There is no British work. For descriptions and 

 classification, see Rabenhorst's " Flora Europrea Algarum."

 a new edition is just published by Robert Hardwicke, 192, 

 Piccadilly. 



E. G. V. — Melampsora populina. 



F. R. M. — We really cannot repeatedly answer the same 

 questions, which a reference to our previous volumes would 

 solve in an instant. Apply to Mr. Janson, Museum Street, 

 Bloomsbury. 



J. W. G.— Apply to Mr. How, Foster Lane, Cheapside, E.C.

 cheap work giving the English and Latin names of British

 other orders.
