HARDWICKE'S SCIENCE-GOSSIP. 



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 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. 



M. Q. C. — I. We do not fear that the use of a monocular 

 microscope will injure the eyesight. 2. We do not think the 

 monocular superior to the binocular, especially for low 

 powers. 



E. L. R. — Alnus glutinosa-laciniata. — B. 

 Dr. J. P. H. B. — Cannot you send specimen ? Have you 

 consulted Dr. Grisebach's " Flora of the West Indies " ? 



J. J. calls attention to " H. E. W.'s " anecdotes, and refers 

 to " Country Life," 18n'7, p. 231, for two of those cited in 

 S.-G. 1871, p. 40; only that the "young lady *' was then a 

 "London nursemaid." Is this an example of "Natural 



e scent" ? 



C. E. — We never attempt to name objects from description. 



J. H. — It seems to be the Mer7nis nigrescens. See S.-G. 

 18G;, p. 221. 



M. A. L. — The only book likely to meet your wants is 

 Cooke's " British Fungi " (Six Shillings), published by Hard- 

 wicke. 



C. W. — We confess that we know nothing of " musical 

 sand." 



C. L. will find an account of the " Coronella" in "British 

 Reptiles," published by Robert Hardwicke, with coloured 

 figure. 



R. T. A. — We are unable to give you any advice as to dis- 

 posal of " preserved insects," &c. 



E. H. — It is very difficult to determine the larvae of beetles, 

 Sec. At present yours are not identified. 



W. H. W. — An Ixodes, probably Ixodes Pari. See Leach in 

 "Linnean Transactions," vol. xi. p. 398. 



F. I. W. — Eurotium herbariorum, 



G. S. T. — Arcyria punicea. 



E. P. P. — 1. Enough benzole to render the dissolved resin 

 of the required consistency. 2. East Indian dammar. 3. 

 Pound the gum, shake or stir whilst dissolving. 4. Yes, it 

 requisite to soak in anything. You seem to have used some 

 other resin (copal ?) ; hence the failure. 



A. B. E — Smallest larva undeterminable in its shrunken 

 state. Large larva, Clisiocampa neustria. Cannibalism in 

 caterpillars not unfrequent.— F. M. 



W. L. W. E.—I'hlomis fruticosa. Ait.— B. 



"W. B. — Rume.r acetosella, L. What botany do you use ? 



B. R. and II. L. — Put them in a bottle with bruised laurel- 

 leaves. 



W. Y. — You are not likely to get it in this country at all. 



S. R. — Have you read our instructions to correspondents so 

 often printed at the commencement of this last page ? We 

 do not insert lists. 



L. R R. — Apparently a Cotoneaster near C. bacillaris. 

 "The Gardener's Chronicle," "Journal of Agriculture," or 

 "The Gardener's Magazine," are more suitable media for ob- 

 taining the names of garden plants. — B. 



G. S. S. — 1. Geranium Rof/erfiunum,'var. ptirpureum. 2. 

 Apparently only Arabia hirsuta more hirsute than usual.— B.' 



S. H. G. — Books are not eligible for exchange list. 



A. E.-We only know of Paxton's "Dictionary," and the 

 " Cottage Gardener's Dictionary." 



E. B.— You will find its occurrence noted in back volumes 

 of this journal. 



S. S. (Brighton)— Please send correct address. 



T. — A trap to catch the unwary. 



W. P. — Too long for exchange column. 



L. P.— 1. You will find an article in the " Popular Science 

 Review," No. 24. 2. The monstrosity you describe is not 

 uncommon. 



F. C— Send larger specimens, and affix numbers. 



H. F. P.—Polyporus rufescens, Fr. Cooke's "Handbook," 

 No. 740. 



J. L. P. — Anthrenus xanthura, Kirby, female. — F. W. 



B. W. (Taranaki.) — 1. Selophilus agerinun, Walk. 1. 

 Musca quadrimaculata. 3. Muscu Lxmica, White. — F. W. 



L. T. — 1. Trichostomum tophaceum. 2. Hypnumfalcatum. 

 — R. B. 



R. V. T. — 1. Bryum cernuum. 2. Sypnum Swartzii. — R. B.
