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 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 enlargemant 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. S. M. — No. 1. On oak-leaf are the spangles mentioned, 

 vol. i., p. 240 of Science Gossip. No. 2. The red fungus on 

 stick is Tuberciilaria vulgaris. No. 3. The black spots on 

 maple-leaf are those of a fungus, Rhytisma acerinum. 



W. H. R. — As there are so many subjects to which no avail- 

 able guide is published, it appears to us good reason for not 

 entering upon the "Adulterations of Food," especially as Dr. 

 Hassell has treated the subject so completely, and, after all, his 

 works are not dear. 



W. T. P. — For obtaining and preparing crystals from the 

 human breath, we refer you to our reply to J. C. M., at page 

 264 of vol. i. 



Diatom Wanted. — If specimen of Coscinodiscus radiafus 

 is sent, postage will be repaid by J. Green, Jun., 19, Pump- 

 street, Londonderry. 



J. A. — It is very unsatisfactory to attempt to name gums 

 from such small samples. No. I. Gum Sandrach. No. 2. 

 African Anime. No. 3. Copal Resin, or probably East Indian 

 Dammar. 



British Land and Freshwater Shells. — Exchange de- 

 sired. List of duplicates and desiderata to be sent to T. M., 

 14, Union-place, Lower Broughton, Manchester. Also to 

 Aperta, 10, Mornington-place, Halifax. 



Harvey P. — No name or address enclosed. 



J. W. R.— Which do you refer to, the Red Peziza or the Red 

 Cup Moss} — for they are not the same thing. 



E. A. C. wishes to know where he can find a Triceratium, 

 which is said to be found in Thames mud, as he has been 

 looking for it two years unsuccessfully in the mud from the 

 river at Chiswick and Hammersmith. 



H. R. W. will find all the information he seeks in Davies on 

 *' Preparing and Mounting Objects." Price half-a-crown. Pub- 

 lished by Robert Hardwicke, 192, Piccadilly. 



G. F. S. (Durham)— We should be glad to receive a copy of 

 the paper you name. 



L. A., E. B., and H. S.— Next month. 



W. B. M. — Try a hot-water plate. It is considered by many 

 preferable to a lamp for mounting; or a tinman would con- 

 struct a water-tight box for hot water, of any size. A simple 

 paraffin lamp answers very well for the microscope. 



A. H. W. — Because one spider did not eat its web is no 

 evidence that spiders never perform such an act. We 

 think it has never been asserted that they always devour 

 their webs. 



H. S. B. — You will observe that mounting crystals receives 

 attention in the present number. We must repeat that 

 mosses abound on all old walls, trees, stumps, &c, if you 

 desire no particular species. 



C. H. recommends soaking in vinegar for some days the 

 leaves from which it is intended to remove the cuticle. His 

 communication was received too late for insertion. 



E. G. advises soaking leaves in water for a few days for 

 the same purpose. 



Carboniferous Fossils in exchange for other fossils. — 

 Address W. W., 29, Heaton Terrace, Bolton. 



S. J. M. — English gnats are quite different insects from 

 tropical mosquitoes, at least from any species of mosquito 

 which we have seen, notwithstanding the quotation to which 

 you refer. 



J. C. W. offers bog-material rich in diatoms, &c, in ex- 

 change. Address, Montpelier House, Budleigh Salterton, 

 South Devon. 



E. G. W.— Next month we shall give several illustrations of 

 the scales of insects. 



H. G. E. — The binocular dissecting microscope maybe used 

 in the dissection of any objects. 



J. H. Ashford, Scarboro', will be glad to exchange British 

 land and fresh-water shells. 



G. H. B.— The caterpillar of more than one small species 

 of moth. 



E. S. — Wherever the information is supplied with the 

 figures, your suggestion will be carried out. 



Diatomaceous Earth. — If any one having a duplicate 

 specimen will forward it, stamps will be returned by W. C, 

 62, Kirkgate Street, Leeds. 



J. B.— A modification of your suggestion is under con- 

 sideration. 



Zoophytes. — Unmounted specimens offered in exchange 

 for earth or sand containing Foraminifera, by J. R. E., West- 

 field Cottage, 9, the Mall, Newport, Isle of Wight. 



A. L. — Your Fly from Iceland is also common in England ; it 

 is the Sand-fly (Simulia reptans, L.), and swarms in Lapland 

 and other Arctic regions ; it is very pertinacious in sucking 

 blood.— F. W. 



Dissecting Mollusca.— Consult "Tulk and Henfrey's 

 Anatomical Manipulation;" the articles Articulata and 

 Mollusca in Todd's " Cyclopaedia of Anatomy;" " Papers on 

 the Anatomy of Gasteropods," by Dr. Lawson, in " Intellectual 

 Observer" for 18*13; Rymer Jones's "Animal Kingdom;" 

 Lacaze-Duthier's Papers in the " Annales des Sciences Natu- 

 relles" for the past five or six years. The subject is one of 

 vast proportions. Let Frank dissect the nervous system of 

 the common slug, following Dr. Lawson's directions. This 

 alone will occupy some time. — H. L. 



Aquarium Animals.— Mr. W. A. Lloyd would be glad to 

 place himself in communication with any one willing to 

 supply living aquarium animals on liberal terms. Payment 

 and delivery to be made near London.— Address, Zoological 

 Gardens, Hamburg, Germany. 



R. M.B.— The Gray Plover, Turnstone, and Peewit, have all 

 a hind toe, whilst the Golden Plover, Thicknee, and Dotterel, 

 have not. 



H. S. — We cannot venture to name a spider from brief 

 description only. It can only be done satisfactorily from 

 specimens.
