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 can be taken of communica- 

 tions which do not contain the name and address of the 

 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. We do not 

 undertake to return rejected manuscripts unless sufficient 

 stamps are enclosed to cover the return postage. Neither 

 can we promise to refer to or return any manuscript after 

 one month from the date of its receipt. All microscopical 

 drawings intended for publication should have annexed 

 thereto the powers employed, or the extent of enlargement, 

 indicated in diameters (thus : x 320 diameters). Communi- 

 cations intended for publication should be written on one 

 side of the paper only, and all scientific names, and names of 

 places and individuals, should be as legible as possible. 

 Wherever scientific names or technicalities are employed, it 

 is hoped that the common names will accompany them. 

 Lists or tables are inadmissible under any circumstances. 

 Those of the popular names of British plants and animals 

 are retained and registered for publication when suffi- 

 ciently complete for that purpose, in whatever form may 

 then be decided upon. Address, No. 192, Piccadilly, 

 London, W. 



N. K.— Drawings to illustrate papers must be executed 

 sufficiently well to be copied 011 wood, but contributors are 

 not required to draw them on wood. Failing this, the objects 

 themselves should be forwarded, so that drawings may be 

 made therefrom. The latter plan is preferable, unless the 

 drawings are well done.

 description.

Mosquitoes. — " D. B." should consult Science-Gossip

 ot the female.

 fungi, accurately named and arranged, at the office of this 

 journal, for 12s. 6d. 



W. B. L. — If you will send a specimen of your plant we will 

 name it for you ; we do not quite understand your descrip- 

 tion. The book you name is out of date ; you should get 

 some more modem manual — say Hooker's " Student's Flora."
