HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



W. N. — The East London Naturalists' Club, 23, Fairfoot 

 Road, Bow, is likely to suit you. We are but few in number at 

 present, but I do not know of any club of the sort nearer 

 than this. The Secretary, Mr. J. W. Love, at23, Fairfoot Road, 

 will furnish further particulars. — J. R. D. 



Micro. — Get the work on " Collecting: snd Mounting 

 Algae," from Hardwicke, 192, Piccadilly. It will give you 

 exhaustive information on all you require. 



E. E. Matthews. — There is no royal'road to the study of 

 Botany, You had better get Dr. Master's little work on 

 Botany, or Professor Balfour's, both cheap and just published. 

 A gardener would not be able to give you much help. Cole- 

 man's " Trees and Hedges " would assist you in associating 

 your feeding insects with leaves. 



J. H. E. — There is no Entomological Dictionary published- 

 Shuckard's translation of Burmeister's Manual of Entomology 

 contains definitions of great numbers of entomological terms, 

 but it was published long before the work of which you speak. 

 The most useful book for your purpose would be Staiixton's 

 " Manual of British Butterflies and Moths," which contains 

 a glossary of its scientific terras. — C. G. B. 



E. C. MoRELL. — Your question is a difficult one to answer. 

 Damp and old woodwork are probably the cause of the ap- 

 pearance of the LepismoB in such numbers. Benzine and 

 camphor would probably keep them off" your books, but the 

 smell may be objectionable. You had better seek for and 

 destroy the home of the insects. 



R. H. N. Brown. — Our correspondent will find full par- 

 ticulars of the new voltaic batteries in a lecture delivered 

 Dec. 11, before the Society of Arts, and published in full in 

 the Pharmaceuticiil Journal, Dec. 23 (Churchill). The lecture 

 was delivered by the author of the paper at Brighton, the Rev. 

 H. Hig-hton, M.A. 



E. B.^The white-flowered Centaury is not uncommon. It 

 is merely a variety of the common form. 



J. P. — The moss is Dicranum bryoides. 



T. G. — Your specimen is not a lichen. It is difficult to tell 

 what it is. We have shown it to several good authorities, 

 but none of them can make it out. 



E. C. J. — Your zoophytes are as follows : — No. \,Serialaria 

 lendige.ra, damaged specimen, the secondary polyp-cells 

 almost entirely worn away. No. 2, Bugula amcularia, variety, 

 developing in some parts a multiserial arrangement of the 

 polyp-cells.— W. S. K. 



W. Z. — The following are the names of the Hepaticae sent 

 to US; — 1. Mctzqeria fiircata ; 2. Jungermannia crenulata ; 

 3. Lophocolea bidentnta ; 4. Cnlypogeia trichomanes ; 5. Jung, 

 inflata; 6. Jung, ventricosa, v. gemniifera. — B. C. 



F. Fletcher. — The incrustations on your piece of coal 

 were not fungoid or lichen growths, but minute radiated 

 crystals of WUherite, Examine them with a low power. 



A. D. — Our space forbids us, as a rule, answering other 

 than natural history questions. You will find full instruc- 

 tions, if we remember right, how to construct a Sundial, in 

 Lardner's " Museum of Science and Art." 



M. J. G. — Mosses:—!. Hypnum cupressiforme ; 2. and 3. 

 S, sylvaticum ; i, H. molluscum ; 5. H. filicimimwiiXh Tricho- 

 tomum rubeltum ; 6. Scupania undulata. — R. B. 



J. S. — We are much pleased with your slide. The section 

 is beautifully cut, and the carmine staining exquisite. 



W. N. will accept our thanks for sending us a capitally 

 executed pen-and-ink sketch of the common double poppy, 

 in which the seeds have been retained and, perhaps owing to 

 the continued warmth and wet, have sprouted. The eff'ect is 

 very singular and uretty, the seed-vessels proper appearing 

 like vases, in which minute plants are growing. Our kind 

 correspondents must pardon us for not insertuig the great 

 number of instances, which have been sent us, illustrative of 

 the mildness of the season. They would fill the present 

 number at least. 



R. W. W.— The vertebra is that of the Blue Ray (,Saia 

 batis). 



A Country Subscriber wishes to know where he can ob- 

 tain a set of diagrams for a lecture on the Microscope. WUl 

 some of our readers kindly help him to the information ? 



Dr. J. P. H. B. — Your sketch of the conifer called 

 " Jerusalem Candlestick-tree " is scarcely enough for iden- 

 tification. You had better send us a leaf or two. It is, how- 

 ever, most probably Pudocarpus coriaceus, Richard. — W. C. 



J. M. D. Ashbury. — Your mounted specimen of the skin of 

 the Smooth Newt was not sent in a sufficiently strong case. 

 It arrived utterly smashed ! 



CoRREsroNDENCB. — Wc must rsqucst the patient forbear- 

 ance of many correspondents whose communications have 

 not yet appeared, as we receive so many that we cannot 

 pablish half. 



S. Tagg, Bryum, p. Bailey, &c. — Answers in hand. 



Birds' Eggs. — Will the correspondent who sent us birds' 

 eggs to name send his address ? It has been mislaid. 



M. Turner. — Your fern is Adiantum hispidum. — J. B. 



S. O. — If the blotches on your pupa are external, and can 

 be rubbed off, they are merely caused by some moth which 

 has emerged in the same cage. These would not injure 

 your pupa, unless they hindered the bursting of its shell by 

 binding the sutures together. But if the blotches are internal 

 — actual changes of colour, they probably indicate that the 

 pupa is dead. There is no need for wetting pupae kept in 

 moss.— C. G. B. 



Joseph Anderson. — Wilkinson's "British Tortrices " 

 contains illustrations of twenty-four species and descriptions 

 of all those known at the time of publication ; Stainton's 

 " Manual of British Moths," upwards of thirty illustrations, 

 besides the descriptions. These works are both published by 

 Van Voorst, 1, Paternoster Row. There is no other British 

 work answering to your description.— C. G. B.
