HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



To CORKESPONDENTS AND EXCHANGEES — As we nOW 



Dublish SciENCE-GossiP earlier than heretofore, we cannot 

 DOS bly insert in the foIlowinK number any commnn.cat.ons 

 which reach us later than the 8th of the previous month. 



To Anonymois QuERisTS.-We receive so many queries 

 which do not bear the writers' names that we are forced to 

 adhere to our rule of not noticing il.em. 



To Dealers and others.— We are always glad to treat 

 dealers in natural history objects on the same fair and general 

 Kro ,nd as amateurs, in so far as the " exchanges "offered are fair 

 «ch"nKe.. but it is evident that, when the.r offers are s.mply 

 disRv^ised advertisements, for the purpose of evading the cost of 

 adx ertising. an advantage is taken of our ^ra/»,/<;«f insertion of 

 "exchanges" which cannot be tolerated. 



M. Thompson.— Your specimen is I.astrea recurzia. 

 T W RicHFORD (Wells, Norfolk).— Many thanks for your 

 tnily magnificent bouquet of ma.ine nowering plants. One is 

 the sea lavender (Statke limoniumj, and the other the sea 

 wormwood (Arieviisia maritivia). 



Thomas Bovle. — Vour crustacean is the squat lobster 

 iCalathca strit^osah Sec notes on " Preserving Crustaceans, 

 by Mr. E. Lovett, in Science-Gossip vol. for 1880. 



E C Thompson (Tunbridge).— White varieties of Lamium 

 {.ur'bureuni are not uncommon in most localities. We believe 

 that the tendency to produce white varieties on the part of 

 very common plants is in order to avail themselves of the fer- 

 tilising agency of moths in the evening, when such a change of 

 ordinary colour would be most serviceable. 



I Salnders (Luton).— Accept our best thanks for specimens 

 oK Leucobryum slaucuvt (and varieties), as well as of Malaxis 

 paludosa from Brockenhurst. 



E R. Cowi.EY.— "La Science pour Tous," " Cosmos : les 

 Mundes," " Keuille dcs Jeunes Naturalistes," " Le Monde de 

 la Science," are all cheap popular French scientific journals, 

 excellently edited, which would suit your wishes admirably. 

 "Cosmos: les Mondes" is a weekly magazine. There would 

 be no difficulty in getting them through Mr. C. Collins, 157 

 Great Portland Street. 



H. C. OvEV.— You will find an .nrticle by J. E. Taylor de- 

 scribing a Derbyshire cavern in the August number of Science- 

 Cossip for 1879. The paper entitled "A Lady's Visit to a 

 Derbyshire Cavern" appeared in Science-Gossip for March 

 1880. Each part is 4^. 



Q H. G.— Your rose-leaf is an illustration of what Dr. 

 Masters, in his valuable work on " Vegetable Teratology," 

 terms pUiophylly, or " leaf-excess," a small supernumerary leaf 

 shooting from the mid-rib of the ordinary leaf. 



J. Rasor.— The specimen is very curious. — We will answer 

 your query in our next issue. 



W. M. C. C — The insects mentioned (p. 189) are not bees, 

 but the hawthorn saw-fly {Trichiosoma lucorum), the larvae of 

 which may now be found upon most hedges ; but as they feed 

 at night, they often escape notice, and the cocoons arc most 

 frequently seen in the winter months.— /^rfi/. Enoch.
