HARDWICKE'S SCIENCE-GOSSIP. 



[Jan. 1, 1S70. 



NOTICES TO CORRESPONDENTS. 



All 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 nan 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 he 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 scientificnames, 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 sufficiently 

 complete for that purpose, in whatever form may then be 

 decided upon. Address No. 192, Piccadilly, London, W. 



J. M. — Entirely foreign to our " Exchange" column, and 

 can only be inserted as an advertisement. 



R. T. A. — Probably there has been some mistake, and 

 " Hereford " may have been read for " Hertford"— illegible 

 writing therefore incurs the blame. This would exonerate 

 " R. T. A." from any wilful attempt to mislead us or our corre- 

 spondents ; still, if we insert " exchanges " gratuitously, we 

 claim the right to exercise supervision. In the conviction 

 that carelessness on the part of some one led to the insertion 

 of the notice in our last issue, we exonerate " R. T. A." from 

 any charge of unfairness, and can only hope that he will 

 accept our expression of regret that any suspicion should 

 have attached to him. 



B. T.— We cannot, under any circumstances, insert books 

 or requisitions for books in the "Exchange" column. 

 Apply to Mr. Wheldon, Bookseller, Great Queen Street, W.C. 



A. I. — It was probably the young of the black variety of 

 the adder. We could not determine from rough description. 



J. W. — One is the " Mealy Guelder Rose," and the other 

 the common " Cornel," but no numbers were attached. 



F. G. might generally obtain what he wants in that line 

 by sending a stamped envelope to the Editor of Science- 

 Gossip. 



Caligraphv. — If our correspondents will not take the 

 trouble to write their " Exchange" notices distinctly and 

 legibly, especially names and addresses, we cannot insert 

 them. 



F. W r . Marrat, 32, Empire Street, West Derby Road, 

 Liverpool, and not Kensington, as previously given in Ex- 

 change column. 



W. E. P. — We do not see that your note adds any informa- 

 tion on either word, and is merely curious. 



J. H. M. — Only by exchange. Consult our Exchange 

 notices, as " sections of wood " were lately offered. 



A. J. — Too long to insert entire, as you will see by a refer- 

 ence to past numbers and notices. 



R. L.— Every entomologist knows that Ganepteryx rhamni 

 appears erratically in all sorts of wintry weather. 



Name Labels, W. F. H. — Our readers will observe the 

 advertisement in the December number of your printed 

 name labels for slides. 



C. B. R. will find an advertisement of the " Birds of Somer- 

 setshire " in the last number of Science-Gossip, at p. cliii. 

 " The Birds of Sherwood Forest," by W. J. Sterland (Reeve). 



W. G. M. — For mounting crystals see Science-Gossip for 

 1SG6, pp. 19, 33, 135. For cutting Echinus spines see " Davies 

 on Mounting," pp. 99. 



G. B. — We insert no notices of exchanges in which books 

 are included. 



Erratum. — At page 273 of our last number, top of second 

 column ; 600 is printed instead of 60. 



R. D. may obtain " Ligurian Bees " from Mr. Pettitt of 

 Dover. 



E. M. H. is too late, being a " day after the fair." 



J. C. G. — We know of no such a book. 



A. P. — Eighteen-pence (Van Voorst). 



J. C. D. — The fern is Asplenium adiantum-nigrum. 



W. L. W. E. — At present uncertain. The Hepaticce are in 

 preparation, and will follow the flowering plants. It depends 

 very much on the success of this, whether the mosses are also 

 published.
