HARDWICKE'S SCIENCE-GOSSIP. 



[Aug. 1, 1867. 



NOTICES TO CORRESPONDENTS. 



Alt. 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 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, Piccadilly, London, W. 



P. B. — Your brand is Pnccinia Lychnideavum, which is 

 quite different from the wheat mildew. 



E. T. S.— In using "immersion" objectives, a drop of 

 water is placed on the lens. 



J. P. — The "tick" from weasel does not seem to be dif- 

 ferent from the Dog-tick {Ixodes ricinus).—W. W. S. 



W. R. and G. T. S. — The remains of organisms received 

 were not in a condition to determine with certainty. The red 

 patches in the water as described by you and seen at the 

 docks, with the fragments received, lead to the conclusion 

 that they were a large species of Daphnia (Science-Gossip, 

 1866, pp. 156-7). 



R. G. A.— We have been informed that a complete list of 

 British Mosses is in preparation, and will shortly be pub- 

 lished. 



H. C. — Have you seen " Liebig's Letters on Chemistry," or 

 "Johnston's Chemistry of Common Life"? A book on 

 " Chemical Analysis " will be of very little use to one " unac- 

 quainted with the principles of chemistry." 



C. P. S.— It is Seaside Barley {Hordeum maritimum). 



W. D. R.— No. 1, the common Weevil {Phyllobius uni- 

 fortius), a pretty object for the microscope; No. 2, the still 

 commoner Bracken-clock (Anomala horticola). — 7. O. W. 



W. H. — All the instruments you require for dissecting 

 flowers will be a pocket-lens (about Is. 6d.) and a good pen- 

 knife. You may have a useful little microscope for three 

 guineas. No book of Biitish moths, coloured, can be had at 

 a low price. 



W. P. W. S.— Only " Insect Transformations," published 

 nearly forty years ago. 



E. A. C— The query has been answered in Science-Gossip. 

 There is no patent method for finding Triceratum without 

 trouble. 



W. R. — No. 2, Atrichum undulatum ; No. 3, Polytrichum 

 piliferum. — R. B. 



T. H., Jun.— No. I, Hypnum rutabulum; No. 5, Ncckera 

 crispa. — R. B. 



J. R. W.— No. I, Antennaria dioica; No. 2, Salix repens.— 

 R. 7.'. 



Jemima.— Hieracium pilosella, very common. 



H. B. H.— Cooke's "Fungi Britannici," cent. Hi., is just 

 published, and can be obtained at 192, Piccadilly. 



T. P. F.— The maple-leaf insect is the curious little Phvllo- 

 phorus testudinatus of Thornton, the Chelymorpha phyllophora 

 of Clark, and the Periphyllus testudoof Van der Hoeven.— W. 



W. M. J.— To determine the genus and species of ferns, it 

 is absolutely essential that the fronds sent to us should 

 possess fructification. 



C. J. T. — We know of no works on British Marine Alga? 

 superior, if equal, to those by the late Professor Harvey. 



Water-filters.— Referring to inquiries as to purifying 

 water, we would recommend that application be made to the 

 Silicated Carbon Filter Company (Battersea) for one of 

 their Illustrated Lists, as these Filters have been spoken of in 

 the highest terms by the Lancet, the Popular Science Review, 

 and the British Medical Journal. 



B. T. — It is really quite out of our power to name so many 

 specimens at a time. We are willing to do all that we can for 

 our subscribers, but this is one of the things that we cannot 

 do. Could not some of our friends think of tbe Editor, as 

 well as of themselves, when they pack up a dozen " odd 

 things " for him to name for them ? 



M. B.— A second issue of Mrs. Bury's " Photographs of 

 Polycystius " is in progress, and will soon be published. 



A. A.— See Nave's Handybook, just published at 2s. 6d. by 

 Mr. Hardwicke, 192, Piccadilly. 



B. R.— We cannot say. Inquire of Mr. King, Portland- 

 road. 



R. S.— In the present number you will find a chapter on 

 Leaf-miners. It is most likely a Dipterous larva which 

 mines the honeysuckle leaves forwarded to us.
