HARDWICKE'S SCIENCE-GOSSIP. 



[Jan. 1, 1869. 



NOTICES TO CORRESPONDENTS. 



All communications relative to advertisements, post-office 

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

 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 Jo 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 

 cannot 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 manu- 

 script 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). Communications intended for publication 

 should be written on one side of the paper only, and all 

 scientific names, and names of places and individuals, 

 6hould 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 inad- 

 missible under any circumstances. Those of the popular 

 names of British plants and animals are retained and regis- 

 tered for publication when sufficiently complete for that 

 purpose, in whatever form may then be decided upon. 

 Address No. 192, Piccadilly, London, W. 



American Deposits. — Two mounted slides of Diatoms re- 

 ceived without name or address, asking for American De- 

 posits in exchange. If correspondents will commit such 

 errors, they must suffer disappointment. 



J. B. C— See Science-Gossip for 1865, pp. 42 and 66. 



J. B. — Probably in the same way as birdskins, for which 

 we have given instructions in earlier numbers of this 

 journal. 



G. H.— Consult Science-Gossip for September, I865, p. 

 nog, with figure. 



H. G. — Not sufficient distinctive character in the eggs to 

 name them.

J. D. H. — Vanessa nrticee.

 those of a parasite (IchneumonidtB ?). 



T. W. wants to know how to determine the age of a parrot. 

 We do not attempt to name anything from " brief descrip- 

 tion," not including specific characters.

Exchanges. — We must caution exchangers against send- 

 ing out such slides as we have lately seen under the descrip- 

 tion 01 " good slides," that are not worth the unground glass 

 on which the objects are mounted. Persons permitting such 

 slides to leave their own cabinets have very little regard for 

 their reputation, and deserve to have them ieturned.— Ed. 

 S. G.
