HARDWICKE'S SCIENCE GOSSIP 



NOTICES TO CORRESPONDENTS. 



TO CORRESPONDENTS AND Exch anoers.— 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 8th of each 

 month. 



W. H.— Dr. Carpenter's Lecture to the Working-Men of 

 Bristol on a piece of Limestone is published in Good Words 

 for October, 1875. 



Dkssau.— We believe the second volume of Nicholson's 

 " Manual of Zoology " was published by Messrs. Blackwood, 

 Edinburgh. 



J. L. V.— It is not an uncommon thin? for the Brimstone 

 butterfly (Goniopteryx rhamni) to be temporarily roused from 

 its state of hybernation by an unusually warm day, so as to 

 be seen fluttering in our lanes. 



Robert East.— The beetle is called Pristongchus terricola, 

 a very common species. The Hair-worm you took from it is 

 undoubtedly the Gordius aquations, or common Horsehair 

 worm of our ditches, which, in its earlier life history, is 

 parasitical within beetles and other insects. 



B. H.— The sport in the Helichrysum sent us is not un- 

 common in composite flowers, although it is not so often met 

 with in the everlastings as in the daisy, &c. See Masters's 

 " Vegetable Teratology " for an explanation of monstrosities 

 of this kind. 



F. A. Lake.— We should think any large nursery gardener 

 would be able to supply you with the ferns you name. Apply 

 to Messrs. Hooper & Co. 



E. H. (Sheffield).— The date you name, December 29th, is 

 very early for the Skylark to commence its song. But it 

 usually begins in January, if the weather be open and mild. 

 Undoubtedly it was owing to the unusually warm weather at 

 the end of December that you heard it. We ourselves heard 

 the Missel Thrush in full song on the forenoon of the 24th 

 December last. 



R. S. Thomas.— The " Micrographic Dictionary," published 

 by Van Voorst, is the best book a hardworking microscopist 

 can obtain for such purposes as those you mention. 



W. J.— The mineral you forwarded to us from a coal-seam 

 in the neighbourhood of Swansea is sulphate of lime. 



Xkno. — Get Cooke's " Microscopic Fungi," with coloured 

 illustrations, published at 6s. by Hardwicke, 192, Piccadilly. 



Robert W. — Your fossil coral is Holysites catenulatus, 

 commonly called "Chain Coral." It is one of the character- 

 istic forms of the Upper Silurian rocks. 



Ada P.— Loudon, in his " Hortus Britannicus," gives the 

 origin of the generic name Paris (in Paris quadri folia), as 

 derived from " par, equal ; regularity of parts." 



P. O. — Write to Hardwicke, 192, Piccadilly, for their cata- 

 logue of scientific works. You will find there more than one 

 work of the kind you want. 



Greenwood. — If you apply to Messrs. R. & J. Beck, 31, 

 Cornhill, London, you will obtain all the information you 

 seek concerning the Reflex Illuminator, and likewise its 

 adaptation to the microscope you name. 



H. J. Ryder. — For information concerning chalk fossils 

 consult Mantell's " Medals of Creation," Taylor's '* Geo- 

 logical Stories," Nicholson's " Manual of Palaeontology," 

 Owen's " Palaeontology," the volumes of the Palaconto- 

 graphical Society of London, the Decades of the Geological 

 Survey, Dixon's " Geology of Sussex," and Whitaker's 

 " Geology of the London Basin.'' 



C. — Obtain Nicholson's "Advanced Text-book of Zoology,'' 

 and you will there find all the information you require con- 

 cerning the locomotion of lobsters, and the organs which 

 produce it. 



R. N.— See Gosse's " Naturalist in Jamaica " for a detailed 

 account of the motions of the Flying-fish (E.rocwtns vulitans) 

 as witnessed by himself. There can be no doubt of its power 

 to rise and fall in the air, and even to beat the atmosphere 

 with its extended fins. 



N. T. S. — Your plants are (1) Galeopsis versicolor, (2) Pru- 

 nella vulgaris, (3) Linaria utitissima. 



P. Howell. — The " Migrographical Dictionary" is pub. 

 lished by Van Voorst. 



E. Sandys. — The Zoologist is still in circulation, and edited 

 by the well-known naturalist, Edward Newman.
