HARDWICKE'S SCIENCE - GOSSIP. 



[Jan. 1, 1SG7. 



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 can be taken of communi- 

 cations which do not contain the mime 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 

 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 

 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 inad- 

 missible under any circumstances. Those of the popular 

 names of British plants and animals are retained and regis- 

 tered lor publication when sufficiently complete tor that 

 purpose, in whatever form may then be decided upon. 

 Address No. 192, Piccadii.lt, London', W. 



B. — The mosses are — 14, Rhyncostegium depressum ; 15, 

 Eurhynchium Swurtzii ; )6, Nec/cera complanata. — R. B. 



F. S. — What kind of information is desired about truffles? 

 See an article in " Popular Science Review," vol. i., p. 496 ; 

 also Sciknck Gossip, vol. i., pp. 89, 139. 



A. L. D. — The moss is Philonotis fontana, var. y, falcata. — 

 R. D. ' 



C. P. C. — From the sketch your fungus appears to be 

 Agnricus (Co/lybiu) radicatus, but the rooting portion is 

 broken off. 



J. P. — Aeckcra crispa. 



H. H. M. — No larva enclosed. 



D. R. — We much regret to learn that H. Balls, of Reedham, 

 has failed to fulfil the engagements of his advertisements in 

 our columns at the close of la>t year. The publisher exercises 

 all the caution that he can to prevent other than bond fide 

 advertisements being admitted to our pages, but manifestly 

 he cannot make inquiries into the particulars of every adver- 

 tisement that is sent for insertion or the character of the ad- 

 vertiser. 



S. J. B.— Of course it does. 



J. G. — No prospectus received. 



M. D. — We have never made solutions of corrosive sub- 

 limate in spirit by weight or measure ; it should be very finely 

 powdered, and we should think two grains to the ounce 

 sufficient. It does not injure the specimens. 



J. W. I.— Your parasite is Puccinia compositarum. 



H. W. K.— The galls on oak-leaves were at one time regarded 

 as fungi, were published as such in collections of fungi, and 

 are often sent to us as " a curious fungus." 



G. A. W. — We could not answer your query here, and you 

 did not enclose full address. 



E. F. W.— No one could even guess from such a description. 

 Was it an Amoeba ? 



A. L. — Certainly no improvement on the very cheap wire- 

 clips which can now be purchased. 



T. P. F. should write his queries separately, and on one 

 side of the paper, otherwise we cannot insert them. 



J. J. R. should have been quite sure that we were wrong in 

 printing aterrimus, at p. 273, before calling us to account. 



A. G. — Safe this time. We cannot say when " Groser's 

 Beetles" will be published. It is impossible to name your 

 foreign gasteropod from its tongue. Beetles not yet named. 



B. D.-We have already figured a fountain, Sciknck Gossip, 

 vol. ii., p. 14 ; and yours is no improvement. 



W. C— " London Catalogue of British Plants," 4d., Dulau 

 & Co., Soho-square. 



J. A. (Mile End).— The fungus is Agaricus ostreatus. 



J. H. G.— See p. 19 in this number. Single slides may be 

 transmitted safely in the black millboard cases sold by all 

 opticians. 



F. HintTON (Powick). 1 Letter awaits yon. Send correct 

 A. Badger (Eccleshall). j address. 



G. F. P.— The section "Mineralogy" in " Orr's Circle of 

 Sciences," or " Weale's Mineralogy," will either of them suit 

 your purpose : at from one to two shillings. 



A. A. A. — We object to recommend any special maker of 

 microscopes. A useful instrument may be had for j£'5 of more 

 than one maker. Dr. Lankester's " Handbook of the Aqua- 

 vivarium " is being revised for a new edition. 



B. D. — The mycelium of some fungus, proceeding from an 

 old stump or decayed vegetable matter. 



H. G. (Bangalore).— The title of the book is "A General 

 History of Humming Birds, or the Trochilidse, with especial 

 reference to the Collection of J. Gould, F.R.S.," by W. C. L. 

 Martin. 12mo., London, H. G. Bohn, 1861. 



J. A. B. is reminded that the letters which he alludes to are 

 the initials of certain societies of which the person using them 

 is a fellow or member. They have no relation either to aca- 

 demic honours or to scientific attainments, since, with scarcely 

 an exception, money, to pay for admission and annual fees, is 

 the only real sine qua non. 



Bangalore. — The Australian acacia is Acacia dealbata. — 

 J. G. B. 



J. B. L.—" Berkeley's Introduction," £ 1." Is., Bailliere. 

 " Hooker's Jungermannise," out of print, and scarce. 



J. H. C. — If he requires more than we insert in our ex- 

 changes, it must be paid for and inserted as an advertisement. 



R. B.- — Bryum Atropurpureum, 



S. L. B. — A mistaken notion. Replace your camphor, or, 

 if you prefer it, try benzine. More on the subject next month. 



T. H. H— No. 1, Xylophasia polyodon ; 2, Polia Chi; 4, 

 Hypena probosctdaHs ; 3 and 5, in too bad a condition for 

 identification. — F. M.
