HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



All communications relative to advertisements, post-office 

 orders, and orders for the supply of this Journal, should he 

 addressed to the Publisher. All contrihutions, 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. 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 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 inadmissible under any circumstances. 

 Those of the popular names of British plants and animals 

 are retained and registered for publication when suffi- 

 ciently complete for that purpose, in whatever form may 

 then be decided upon. Address. No. 192, Piccadilly, 

 London, W. 



W. L. W. E. — The moss is Hypnum rimilare.— R. B. 

 W. J. — Your moss is Hypnum riparium. — R, B. 



J. B. — Your specimen is a dwarf form of Grimmia patens. — 

 R.B. 



H. E. W. — Ranunculus repens, the commonest British 

 species. We do not undertake to name specimens which the 

 smallest amount of attention would enable any one to deter- 

 mine.— J. B. 



E. H. — We have not read the work, but have heard it 

 spoken of as a commendable compilation. 



R. Cooke, Jun. — Your notice is quite out of order. You 

 should have secured the address of " Microscope." 



T. B. — A small specimen of Peziza coccinea. 



W. W. S. — "The Journal of a Naturalist" was written by 

 Knapp, and published by Murray. We know of no Botanical 

 Exchange Club in London. The Botanical Society of Edin- 

 burgh, we believe, exchanges specimens, 



H. B. — Oh yes, very common. 



S. M. P.— Only a variety of Yitis vinifera. — L. 



J. C— Just what is wanted. We do not know of one that 

 we could recommend. 



H. S.— Only Stainton's "Tineina." 



S. A. H. — We knew a "tabby "and a white cat do the same 

 thing; therefore the argument fails. Pray\io not write with 

 such wretched ink : we could scarcely decipher your com- 

 munication. 



A.N. — Wonderful! Did you never discover that before? We 

 thought it was known to every school-boy. 



H. M.-Wc know of no text-book for Polyzoa. 



R. G.— The specimens are Hypnum pi/i/erum and Plagio- 

 rhila asplenioides. — R. B. 



R- V. T. — No. 1. Hypnum serpens. No. 2. Squamaria len- 

 tigera. This Lichen has only been recorded from two British 

 stations, both south of Derbyshire. Can R. V. T. send more 

 of it?— R. B. 



EXCHANGES.
