HARDWICKE'S SCIENCE-GOSSIP. 



[Maech 1, 1SG9. 



NOTICES TO CORRESPONDENTS. 



Am. 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 whutener 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 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 

 fineries 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, Piccadilly, London, W. 



J. R. M.— The black shining threads with small globose 

 heads are Blucor phycomyces, a fungus. 



Mildness of the Season. — We have resolved to commit 

 all the multitudinous communications we have received on 

 this subject to a snug locker to await a sharp frost. 



A. F.-We think that the fumart is settled. 



T. P. B. — If you please. 



E. C. T. (Formosa).— The eggs of an insect, probably Lepi- 

 dopterous. 



R. G. 1, Stoke) .—The last answer was not for ycu. The 

 curious object is not yet identified. 



F. F.— A complete list of British beetles will be found at 

 the close of Rye's " British Beetles" (Reeve & Co.), but no 

 "manuals" containing descriptions of genera and species 

 since " Stephen's Manual " (1839), now almost obsolete. 



G. J. D. should make friends with some ornithologist, or 

 purchase an elementary book on the subject. We have no 

 space to spare for descriptions of the typical form of a duck's 

 foot or a squirrel's tail. 



A. M.— We cannot name objects from description. Consult 

 Douglas & Scott's " Hemiptera Heteroptera " (Ray Society). 



No Name.— If correspondents persist in withholding their 

 names and addresses, or using fictitious ones, they must be 

 content if their queries remain unanswered. 



S. J. N.— Not in our line. 



H. W\, F. J. W.— Ineligible for exchange column. 



E. T. D.— Polyporus versicolor, very common and variable. 

 H. W. G. — There was one, but it appears to be almost, if 



not quite, extinct. We know of no other. 

 W. P. — The fruit of a palm, perhaps a Calamus. 



D. P. P.— We have no doubt of it, although not in flower. 



F. W. — It is clearly a Myriapod, probably Polydesmus com- 

 plunatus. — F. M. 



J. CD. — 1. Fontinalis antipyretica. 2. Bartramia pomi- 

 formis. 3. Tortula Hornschuchiana. — R. B. 



J. C. M.— 1. Hypnum palustre. 2. H. uncinatum. 3. H. 

 irriguum. 4. Blindia acuta. 6. H.praslongum. — R. B. 



W. E. — 1. Hypnum cnprcssiforme. 2. Somalia trichoman- 

 oides.—B. B. 



T. S.— The " Barilla, ria paradoxa attached to a splinter of 

 floating Dantzic timber" explains itself. It came from a 

 marine or brackish station with the diatoms on it. Can it 

 be shown that this same species is found in the canal, 

 Regent's Park, or any other fresh water not in communica- 

 ion with a tidal river ? 



E. W.— Cooke's " Structural Botany " (Is. fid.), published 

 by Robert Hardwicke: Bentham's " Handbook of the British 

 Flora " (12s.), published by Reeve & Co. The least expenshe 

 microscope worth purchasing is three guineas.

 other locality, and to correspond for that purpose. Good 

 specimens only exchanged. — W. V. Andrews, 130, Charlton 

 Street, New York.
