HARDWICKE'S SCIENCE-GOSSIP. 



[Oct. 1, 1S6S. 



NOTICES TO CORRESPONDENTS. 



F. Smail (Jedburgh).— Your Polygonum is the form of 

 P. convolvulus referred to in Bab. Man., ed. vi. p. '296, as 

 having the " perianth winged, when the plant is olten taken 

 for P. dumetorum." — B. 



J. H.— Eggs of a moth, probably the " Lackey," Bombyx 

 netistria. 



G. B.— The moss is Cinclidotus fontinaloides.—R. B. 



R. A.— No. 1. Bryum coespiticium, male plants. No. 2. 

 Fissidens exilis. — R. B. 



A. J.— No. 1. Hypnum chrysophyllum. The other is hi. 

 physcium. — R. B. 



E. C. B. (Portland.) — Weisia controversa, and not Weissia 

 commutatu, as stated in last number.— R. B. 



W. E. — There is no English edition of Blanchard's " Meta- 

 morphoses of Insects." 



H. M. M.— The average temperature varies a little every 

 year, in some years more than others ; the friend who told 

 you that it was permanently 50$ around London should be 

 sent to Coventry. 



F. W. B. — Most probably the Privet Hawk-moth (Sphi?ix 

 Ligustri), but the sketch is too rough for certain identifi- 

 cation. 



Oak Spangi.es are described and figured in Science- 

 Gossip for 1866, p. 228. 



J. R. M.— The white bodies on sandstone are the eggs of 

 the stone mire, Tromoidium (Tetranyc/ius) lapidum. See 

 Science-Gossip for I867, p. 126. 



Errata.— In our last number (p. 210), " Abnormal Fox- 

 glove," the word " bracts " is three times printed " tract?." 

 The P. D. thinks the paragraph must have been " set up " on 

 Saint Monday. 



B. T.— Incrustation of carbonate of lime. 



J. B. (Leeds.) — We will not hazard naming objects from 

 description only. 



J. H. R. — White Plume-moth (Pterophorus pent adacty his). 



G. S. B. — If you want desciiptions of the perfect insects 

 which are evolved from the larva; known as the glowworm, 

 consult " Stephens's Manual of British Beetles," p. 187, under 

 Lumpyris noctiluca. 



W. G.-We have several times received the dendritic spots 

 on paper, and cannot give any satisfactory account of them. 

 They do not exhibit organic structure. 



C. D. — There is nothing at all uncommon in your pods or 

 notice. 



H. S. — As secretary to a naturalists' society, you should be 

 careful in writing ^scientific names, and when quoting two, 

 not to spell them both wrong. Your remedies are old ones. 



M. J. W. — Warne's " Fern-book for Everybody " gives 

 instructions for raising ferns from spores. See also Science- 

 Gossip for 1866, pp. 46, 96. 



T. P. B.— Offer declined with thanks. 



J. H. — The shells of Spirorbis nauti/oides, very common. 



F. R. M. — The black caterpillars of the turnip, called " Black 

 Jack," are the larvae of a Hymenopterous insect, the Turnip 

 Saw-fly, Athalia spinarum. 



L. E. W.— No. 1. Possibly Grateloupia. 1. Desmarestia 

 liguluta. 3. Ectonarpns, species indistinguishable. 4. En- 

 terumorpha, species indistinguishable. Such specimens are not 

 worth the trouble of collecting. — IF. H. G. 



R. (Strand.)— No. 1. Polysiphonia, sp. 2. Sphacelaria 

 scoparia, autumnal state. 3. Decaying Callithamnion. 4. 

 Possibly Gflideum corneum. The remark above applies also 

 to these specimens.— IF. H. G. 



M. K. — Seedling of Polystichum aculeatum.—J. G. B. 



J. F. C. — Certainly appears to be a new and singular variety 

 of Cystopteris fiagilis. — J. G. B. 



S. H. — It is not likely that a specimen of Myriotrochus 

 Rinlcii, or the wheel- plates, can be purchased hi England. 

 The locality is Greenland. 



W. H. P. — Covers for binding Science-Gossip can be had 

 at the office for eighteenpence, or through any bookseller. 

 Any bookbinder would bind them. 



A. E. B.— Inquire of W. R. Tate, Esq., Grove Place, Den- 

 mark Hill, London, who can doubtless assist you. 



J. C. D. — No. 2. Orange-growth on stone is Chroolepus 

 aureus, a species of water-weed, or alga. 



G. T. P.— Most probably your "nigger bread" is made 

 from the meal or grated root of the manioc, Jutropha muni- 

 hut, much used as food in tropical countries. 



W. H. — We don't think that anything could be done in the 

 matter, as the authority is quoted, though part is omitted. 



T. W. W.-We will endeavour to discover the cause of the 

 anomaly. It is apparently a riddle worth solving. 



Bifurcated Ferns. — As the query is now fully answered, 

 we cannot spare room for further replies. Thanks to all who 

 have sent communications. 



T. H. G. — Exposure to the air, and keeping the specimens 

 absolutely dry, is the only cure tor mould amongst dried 

 plants. 



W. W. — Second-hand geological books may be had of 

 Wheldon, Great Queen Street, London, W.C. 



M. D. B. — Should see Collins's Binocular Dissecting Micro- 

 scope. 



D. does not name the plants ; the drops may be condensed 

 from evaporation. 



G. S. — Camphor, turpentine, or benzine, and exposure to 

 the air and sun, ot all furs and woollens.
