HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



Editorial.— We are glad to have received so many replies 

 favourable to the enlargement of Science-Gossip, and in- 

 creasing the monthly price to sixpence. We should now 

 like to hear the other side, and shall be extremely glad if any 

 of our old correspondents or contributors who think it is 

 best " to let well alone" will give us their reasons for not 

 altering the character of a magazine which for so many years, 

 we are glad to say, has been most successful. Audi alteram 

 partem must be our motto. 



%* Would our lady contributors deem it an ungracious 

 request if we desired them not to underline, as well as place 

 in inverted commas, so many of their contributions ? It 

 only means pen and pencil work for the Editor to undo, 

 solemnly and painfully, what so many of our fair contribu- 

 tors have been at equal pains to originate. 



R. J. W.— The fungus sent i3 the delicious Morel {Mor- 

 chella esculenta). When dried it is used for flavouring soups, 

 chops, &c. To that use the specimen sent has already been 

 put ! 



James P. (Birmingham).— Apply to Hardwicke & Bogue, 

 192, Piccadilly, who will send you any of the volumes of 

 Swainson's "Naturalists' Library" you may require at the 

 price specified in their advertisement. 



Nemo.— See answer in last month relative to the Linnean 

 Society. 



J. R. Barker. — The geological specimens from the clay- 

 bed you mention are undoubtedly from the "Drift" or 

 Glacial formation. They are all of them fossils derived from 

 older rocks, washed out, re-sorted, and re-deposited. No. 1 

 is a Belemnite ; No. 2, the fragment of an Ammonite. 



R. Manning. — We should like to see a specimen of the 

 " red rain " before deciding as to what it is. Please send us 

 a slide. 



W. Curnow.— Many thanks for the botanical rarities for- 

 warded to us. 



H. J. Savory.— Your specimens of moths are . — 1. Cramhus 

 selasellus, and 2 is a Crambites. You should get Newman's 

 "Moths." 



T. E. Mason.— Your "larva" is a millepede, lulus com- 

 munis. 



H. E. Forrest.— Your egg was so utterly smashed, owing 

 to its being enclosed in a light pill-box, and that again en- 

 closed in your letter, that it was quite unrecognizable. 



A. K. L" — Your plant is a Canadian weed, which has spread 

 greatly in England during the last few years, and is called 

 Claytonia perfoliata. The leaves make an excellent salad. 



E. Duprev. — No charge is made for inserting "Ex- 

 changes " unless they run to more than three or four lines. 



J. H. Campbell (Londonderry). — It is not usual for us to 

 return specimens sent us to be named. The expense of post- 

 age, and the time required, in addition to having the speci- 

 mens named, is very great. Your moths are as follow : — 

 1. Orthosia suspecta ; 2. Epunda lutulenta (female) ; 3. Miselia 

 oxyacanlhcE ; 4. Carabrinu cubicularis ; 5. Cerastis spadicea ; 

 6. Tteniocampa populeti. You had best obtain Newman's 

 "Moths," published by Hardwicke & Bogue, 192, Piccadilly, 

 whose illustrations and descriptions will enable you to iden- 

 tify all the British species for yourself. Such an engagement 

 would give you a better knowledge of the insects than any 

 number of specimens named for you. 



W, E. Sharp.— For information in reference to the New 

 Forest, see Wise's "New Forest: Its History and Scenery," 

 published by Smith, Elder, & Co. Also consult chapters in
