HAKDWICKE'S SCIENCE-GOSSIP. 



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 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. Ifl2, Piccadilly, 

 London, W. 



J. S., jun. — No. 6. Gemellaria loriculata. No. 8. Flustrn, 

 too small for identification. No. 5. Plumularia falcata, now 

 called Hydrallmannia falcata. 



H. M.— No. 6. Sertularia operculata— others not British. 



H. D.— No. 3. Pellea hast at a, Lk. No. 4. Pteris sp. Of 

 Nos. 4, 5, and 6, specimens insufficient to mark the species. — 

 J. G. D. 



R. T. A.— It is a mould, but in too dilapidated condition to 

 determine accurately,— probably l'ulyactis. 



L. S.— Dr. Prior's " Popular Names of British Plants," pub- 

 lished by Williams & Norgate, will just suit you. 



T. P. C. — A quadri-foliate leaf of Trifolium repens, ap- 

 parently ; but we cannot state positively from an outline 

 sketch. 



J. W. C— Had you carefully examined our first volume, it 

 would have saved you the trouble of writing. 



VV. W. E. — Oh, dear no! nothing of the kind. They are 

 very common galls, figured, as well as the insects that pro- 

 duce them, in a previous volume of this journal. 



R. H. W. — Probably a species of Weevil : we should not at- 

 tempt to name it without seeing it. 



W. H. S. — It would have been quite as easy to have ex- 

 amined the water with a microscope as to have asked of us. 

 You would probably have found nothing. 



B. B.— It is useless sending us spotted leaves to name their 

 parasites, unless there is something to examine. The micro- 

 scope would soon inform you whether any fungus is present. 

 The old fable of " the waggoner and Hercules " is worthy of 

 remembrance. 



E. W.— No. 3 is Pol>/podium vulgar?., the others insufficient 

 to name. 



J. F. C. — Wc know of no printed labels for foreign shells. 



J. C— We could not judge unless we saw the manuscript. 



W. H. B. — Numerous communications on aquaria in all our 

 preceding volumes. 



W. N. E. wants to know the best modem work on meteor- 

 ology.
