HARDWICKE'S SCIE NCE-QOSSIP. 



[Nov. ], 1867. 



NOTICES TO CORRESPONDENTS. 



Am, 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 communi- 

 cations 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 

 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 for publication when sufficiently complete for that 

 purpose, in' whatever form may then be decided upon. 

 Address No. 192, Piccadii.lv, London, W. 



J. G. — We are of opinion that if tobacco possesses any dis- 

 infecting properties at all, they are exceedingly minute. 

 Many believe that camphor and tobacco smoke are either of 

 them disinfectants. It is undoubtedly a popular error in both 

 cases. If the only defence which a smoker can advance in 

 favour of his pipe is its disinfectant power, we fear that 

 logically he must give it up. 



W. M. C— Impossible to tell, from its crushed condition, 

 what the insect is. 



W. R. F. — The moss was undoubtedly Fnnaria hygrometrica, 

 which is very common. 



E. C. J. — We have no knowledge of the name. 



J. B. L.— The American Moth Trap was fully described and 

 figured in Entomologists' Monthly Magazine, vol. ii., p. 199. 



C. H. G. — The Domestic Barometer you describe is much 

 more general than you suppose. We saw it in use in Norfolk 

 many months ago. 



M. A. — We do not know the Coccus on ferns as a species 

 peculiarly attached to those plants, it is very like the species 

 found on the rose, and may have strayed by accident to the 

 ferns from some other infested plant. — I. 0. W. 



A. M. E.— We are not aware that any are published. 



C. A. J.— Two or three species of Serpula have the tufts 

 banded with blue. Animals in aquaria require little or no 

 feeding. Lean raw meat in small fragments is recommended. 



E. B. — Don't trouble about feeding them, especially if the 

 tank is large, and not overstocked. 



J. G. A.— It is a gall, but what insect produces it we cannot 

 inform you ; probably a species of Cecidomyia. 



H. T.— Consult " Bechstein's Cage Birds," or " Beeton's 

 Home Pets." 



M. C. T. S.— The Maidenhair Spleenwort is a troublesome 

 fern under cultivation ; at least around London. 



C. L. — Common as swallows in summer. 



B. L. W. — The subject was so extensively commented upon 

 in all the Natural History journals, a year or two since, that 

 we cannot afford space to repeat it. 



T. L. D. — We cannot afford to guess. 



B. G.-We had received a copy of the "List of British 

 Insects " from the author when we made the announcement. 

 The publisher's name was erased, but the author afterwards 

 replied to a querist that it was published by Longmans. 

 Beyond this our own knowledge does not extend. 



F. C. W.— Nos. l'and 2, Diatoma elongatum. 3 and 4, 

 Diatoma vulgare, front and side views. 



Sea-horse (Hippocampus). — We are informed that Mr. 

 King, of Great Portland-street, has some of these singular 

 fish, "all alive," which those who are interested therein 

 should take an early opportunity of seeing. 



W. D. R.— The Beetle is Phrutoru vitellines.— h. 



J. G. — We are afraid that the address is mislaid. 



J. W. I. — The species of Aregma on Rose, raspberry, and 

 wild strawberry often approximate very closely to each other. 

 Too much reliance must not be placed on the figure of a 

 single spore. Some authors unite the rose and raspberry 

 brands under one species. Yours is Aregma gracile if they 

 are really distinct. 



H. G. L. D.— 1, Achillea. 2, Five shillings.
