HARD WICKE 'S S CIENCE -G OS SI P. 



NOTICES TO CORRESPONDENTS. 



To Correspondents and Exchangers. — As we now 

 publish Science-Gossip at least a week earlier than hereto- 

 fore, we cannot possibly insert in the following number any 

 communications which reach us later than the Sth of the 

 previous month. 



B. K. — We do not fear the extirpation of any rare plant by 

 the members of the E.xchange Club. They are all too genuine 

 botanists to assist in such vandalism. 



F. F. (Highbury New Park, N.).—Vour plant belongs to the 

 nat. ord. Uiuhcllifera', and is a woodland species, commonly 

 called Wood Sanicle (Sauicnla Enrajxra, Linn.). 



T. H. (Oldham).— It is probably a plant carried to its present 

 habitat with ballast ; however, it is the rare Lejiidiitm lati/o- 

 Itjeiii. 



W. J. H.— We believe the fern enclosed to us to be A tJiyriusii 

 iiinllc. It is a very interesting variety. 



H. W. T. (Rugby). — We aFways place finely powdered cam- 

 phor, sewed in small flat bags, on all our herbarium shelves, 

 and we are never troubled with insects. Your plants are as 

 follows : — I. JuncHs lainprocarpiis. 2. Quite correct. 3. 

 lUnaiitltc Jliiviatilis ; colour very rare. 4. Not to be found. 

 Kindly send the latter, whatever it be, again. 



M. H. R. (Newcastle). — Your specimens are very interesting. 

 No. I. Cystopteris dciitata. No. 2. C. fragilis. They are 

 now generally merged into a single species, though Francis 

 names them as above. 



E. F. C. (Leicester). — The neat specimens you sent are as 

 follows : Briza media, Linn, (common Quaking Grass) ; Mc- 

 lampyriiin iiioittaHUJii, Joust, perhaps only a variety : Flialarls 

 caiuD-iensis, Linn., not a true native, the product of some bird- 

 cage ; Spcigula a>-7<L'HS!S, a verj^ common weed in cvdtiv.-ited 

 land. Farmers call it " Pickpocket," because it is injurious 

 to most fields where it is found. 



F. Cranford. — The monstrosity in the daisy you mention is 

 that known to botanists by the name of " Hen-and-Chickens " 

 Daisy. See Masters' "Vegetable Teratology." 



J. Ingleisv. — The fragment of rock is a siliceous sand- 

 stone, not unlike the "gannister" rock of Lancashire in com- 

 position, but more granular in structure. 



T. B. T. — The association referred to by Mr. Palmer in his 

 communication to our columns is the " Postal Micro-Cabinet 

 Club." It originated through a discussion in these columns in 

 1873, and you will find all that you require to know, as well as 

 the rules, &c., of the Club, in the December number of Science- 

 Gossip for that year. 



E. Grove. — The .specimen is that of the common Tutsan 

 {Hypericum nndivsii'inuvi). 



T. T.wi.OR. — One of the best books of its kind is Geikie's 

 "Physical Geography," just published by Macmillan. 



\. C. (Market Drayton). — INIorris mentions the fact of several 

 young cuckoos having been kept, by great care, throughout 

 the winter. Worms or occasional chopped meat would serve 

 as food. 



f J. E. Pritch.vrd. — You may obtain artificial birds' eyes of 

 all kinds and in any quantity, from J . (jardner's, naturalist, 

 Holborn, London. 



F. H. S\v.\i,i.ow. — The objects enclosed in a small bottle 

 are the larva: of a species of Ephemera. The larvre of several 

 species of beetles are called " Wire-worms," but perhaps the 

 commonest are the lirva; of Elater, or " .Skip-jack " beetles. 



R. V. T. —Consult the " Micrographical Dictionary." 



N. Wilson. — You will find a capital life-history of the 

 common Ainccbn, and where to find it near London, in the last 

 number of the Popular Science Re-cne'cu. 



A ScnscRiRER. — The cottony substance sent us was the seeds 

 of the White Poplar (^Popuhts alba), covered and surrounded 

 with the usual silky hairs. 



F. MocKLER. — A solution of chloride of lime is one of the 

 best means of cleaning corals, fossil or recent. 



J. J. Morgan. — The chalk-like dust found in a fissure of 

 rock near a coal-seam appears to be Arragottlte. Under the 

 microscope the crystals appe.ar very distinctly, and polarize 

 beautifully. Can you send us a little more '; There was not 

 sufficient to analyze it.
