HARDWICKE'S SCIENCE-GOSSIP. 



[Sept. I, 1869. 



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 ot 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 sufficiently 

 complete for that purpose, in whatever form may then 

 be decided upon. Addrkss No. 1Q2, Piccadilly, London, 

 W. 



Name and Address.— Communications not guaranteed 

 by the name and address of the sender cannot be noticed. 



R.— The figures are too roughly executed to be engraved, 

 and the information no more than we have already given. 



A. P.— We do not insert exchanges of scientific instru- 

 ments. 



G. H. R.— A fungus not uncommon in such situations, 

 named Polypurus igniurius. 



W. C— Most probably lihodites Eglanterite, Hart ; but we 

 found no insects. 



H. L. M. — It is a parasite on the heather and other plants, 

 called " Dodder" (Cuscutti Europeea). 



J. S.— Consult *' Blackwall's Spiders of Great Britain," 

 published by the Ray Society. 



G. E. Q.— The name of the gnat stands corrected to Culex 

 nemorosus. — C. W. 



W. G., Belfast— The aphis was probably Adelgcs corticalis, 

 or A. abietis.— C. W. 



T. V. P. — Address, but no name : hence we could not write. 

 It is of no use on such questions giving a mere negative or 

 affirmative lure. 



E. C— The spiders (male and female) are small darkly 

 coloured examples of Linyphia minuta, Black.— 0. P. C. 



R. V. T.— No. 1 is Chara fragitis, Des. ; 2 is Ranunculus 

 heterophyllus, Fr. — B. 



D. S. H— It is not extraordinary for some barren fronds of 

 the "parsley tern'' to resemble the fertile fronds in their 

 upper portions. Sometimes soti are also produced on parts 

 of otherwise barren fronds. 



S. A. S.— On hawthorn leaves is Septoriu oxyacanthce, 

 Kunze. 



E. L.— Although broken in transit, from the fragments we 

 should think not. 



W. J. H.— The " cingulum,"an accessory to the reproduc- 

 tive apparatus. See E. Ray Lankester's exhaustive papers on 

 the " Anatomy of the Earthworm," Quart. Journul of Micro- 

 scopical Science, 1864-5. 



r. \v. V.— It is best to poison the plants with a solution of 

 corrosive sublimate in spirits of wine. Camphor may keep 

 insects away, but will not kill them. It is a good plan to 

 use a coarse strong-smelling; brown paper for covers, and to 

 air the plants by turning them over, and looking at them 

 every two or three months. A herbarium in constant use, 

 and kept in a very dry place, seldom suffers from mould or 

 insects. 



G. E.— We inserted your long notice la^t month, quite con- 

 trary to practice, and cannot do it again. Three lines is our 

 " exchange'' limit. Some people, it seems, cannot afford to 

 keep a conscience. 



A. Y. — White flowered specimens of Erythrcea centaurium 

 are certainly not uncommon. 



H. G. — It is such a very common occurrence for Vorticella 

 nehuVfera to be attached to Daphnia or Cyclops that we 

 wonder you should have never met with it before. There are 

 figures extant in such a position in a book before us dated 

 1746. 



H. W. — Very like a "hallucination." 



A. E. J. — Galls caused by an insect. See our constantly 

 repeated notices about name and address. 



C. F. G.— The two insects a.re—Chrysis ignita (blue and 

 copper) and IHegachile centunculuris. — C. 0. W. 



B. R. A. E.— The plant sent is Saxifraga aizoides. 



E. C. — The flowers are Calluna, are quite normal, but not 

 fully developed. We cannot tell what has checked the full 

 expansion of the flowers. — M. T. M.
