HARDWICKE'S SC lENCE-G OSSIP. 



NOTICES TO CORRESPONDENTS. 



GEMivt.— It is not at all an uncommon thing: for water- 

 heetles to destroy newts and minnows in an aquarium. 

 Indeed, you could hardly introduce a greater pest. 



W. H— The " Geological Magrazine " is edited by H. Wood- 

 ward, F.R.S., &c., and published by Triibner & Co., 57, 

 Ludgate-hill, London. 



M. Maxwei.i,. — There was no inclosure, either of sedges 

 or anything else, in your letter of tlie 10th of May. 



W. A. Cl.\rk.— Your specimen reached us in a bad state. 

 It appears to be Myosotis collina. 



Wymav.— A good remedy against house. crickets are the 

 leaves of the eommon rhubarb strewn on the floors of the 

 rooms where they are abundant. 



P. Barkkr.— "Half-Hours in the Green Lanes" did not 

 appear in form of separate articles in Scie.vce-Gossip. It is 

 an independent publication, by the same publisher. 



F. M. I — Your mosses are. No. 1, Xerkera cris/m ; 3, A^. 

 cnmplannta : 4, CUmacium dendroiden ; 5, ThuyiiUum tiimaris- 

 ciniim ; 6, Polptrichum commune. No. 2 is a lichen, belonging 

 to the genus Cladonia. — R. B. 



W. B. L.— Your specimens of micro-fungi were both 

 correctly named. The Puccinea malvacearum is very common 

 this year on mallow leaves. — M. C. C. 



Gali,s,&c.— The "hop like " galls on oak, sent us from 

 Corscombe, Dorchester, are produced by an insect called Cvni'ps 

 fecundatrix. Hart. The gall is commonly called the "Arti- 

 choke gall."— C.G.B 



H. R. M.— We believe that Dr. Gunther and other of our 

 best ichthyologists now consider the Whitebait to be the fry 

 of the Herring. We have not heard of the Whitebait having 

 been found in the Mersey. Doubtless the fry of other fishes 

 are sometimes sold as whitebait. 



G. O. HovvELi.. — In your query about the shell called the 

 " Bleeding tooth," you say " you believe " it is found on the 

 west coast of Africa. It is important to know the locality 

 in judging without the specimen. It may be a species of 

 Monodonta. But the shell to which it most nearly answers 

 is Nerita peloronta;— the latter, however, is American. 



W. H.— The fragment of leaf sent probably belongs to a 

 Myosotis, whose surfaces are usually covered with whitish 

 hairs, around the bases of each of which are clusters of pearl- 

 like beads similar to those so benutifuUy shown in your 

 specimen. These pearly clusters are always seen best in the 

 dried leaf. 



A. K. Hastei.l.— The plant sent is the Lamb's Lettuce 

 {Valerianella olitaria). 



William Jenn'ivcs. — You had better consult Juke's 

 " Manual of Geology," edited by Prof. Geikie. You will there 

 find the best account of the mineral changes through which 

 the granites and metamorphic rocks have passed. 



L. S. — The '' excrescences " on the leaves of the hazel are 

 evidently the webs of the Processionary Moth. 



F. W. — 1. Lepidium ciimpesfre, a. very common plant. 2. 

 S'igina apetahi, a perfect weed in garden walks, &c. Ben- 

 tham unites this species with others, under the name of S. 

 procumbent, L. 3. Geum urbanum ? too small and im- 

 perfect for recognition. — J. F. R. 



G. L. H. — You are quite correct about the genus, it is Zotvs 

 siliqitoms, the Winged Pea, a South European species.— 

 J. F. R. 



G. C. D.— Your specimens are— 1. A young seedling fern,, 

 probably Lastren spinulosa 2. Quite correct. Orchis Morio, 

 but there are several other orchids (British) with what you 

 call whole tubers. 3. Tri/oHiim minus, a starved specimen, 

 which makes it resemble T. filiforme. 4. A Carex. Could 

 you kindly send a better and more perfect example ? it is 

 probably a new variety. 5. Only part of a frond, difficult to 

 name, but closely resembles Polystichum angulare.—J.F. R. 

 E.L.— You will find the best account of the Silbury Hill 

 tumulus, as well as of the so-called " Druldical Stones " at 

 Avebury, in Fergusson's " Rude Stone Monuments of Great 

 Britain." The stalactitic-looking specimen \% carbonate of 

 lime, which has been deposited as tufa, round some twig. 

 The fragment of rock is siliceous sandstone, probably Oolitic. 

 W. H. W.— Your box, containing the bat, came duly to 

 hand, but it was in a high state of decomposition, and had to 

 be " treated " before we could do anything with it. It is a 

 specimen of the Great Bat, a."'iioct\i\c" {Ve>:pertilionortuln). 

 Its first notice as a British species appeared in White's 

 "Natural History of Selborne," and it was named allimlans 

 oy that author.
