HARDWICKE'.S SCIENCE-GOSSIP. 



[Nov. 1, 1861. 



NOTICES TO CORRESPONDENTS. 



N. N. (Hamburg-). — If full name and address be forwarded. 

 we will send report and rules of the Quekett Microscopical 

 Club. 



F. W. — Had we formed a good opinion, probably you would 

 have seen some notice. 



H. H. W. — Most likely Saprolegnia ferox. 



Charlotte B. — A specimen of Erica cinerea, in which no 

 flowers have been produced, but in their place close tufts 

 of purple bracts. We have met with a similar occurrence in 

 Culluna vulgaris and other plants.— M. T. M. 



W. G. S. (Dublin). — The barren form of Xylaria hypuxylon, 

 very common. 



F. I. W.— The leaf is elm, and the fungus Dothidea ulmi, 

 very common. 



H. F. P. — The only cheap book on British Lichens is Dr. 

 Lindsay's popular history, at 7s. 6d. (Routledge). 



F. W. Markatt, 6, Kemble Street, Kensington, will please 

 to send correct address. 



L. F. — We could not attempt to say what it is from the 

 vague description. The Convolvulus Hawk-moth is not 

 common. 



S. M. — Drawings were first made from the animals, which 

 were then grouped and photographed. 



A. S. H. — Could you expect us to name from description 

 what such men as Sir W. Hooker, Dr. Daubeny, and Pro- 

 fessor Harvey could not determine after seeing trie object ? 



M. H. O. B. — More than one similar case is recorded in the 

 present volume. 



P. J. D. H.— Is there so much difference between Sep- 

 tember 28th and October 1st to make it worthy of record that 

 you saw a glowworm at the latter date ? 



H. W. H. should look over "Exchanges"; American Dia- 

 tomaceous earth has been offered for six months past. 



H. J. — In the first and second volumes of Science Gossip 

 you will find accounts of parasitic thread-worms. 



W. W. S.— The Coffee-borer of Southern India is Xylo- 

 trnchus qitadripes, Chev. — F. M. 



M. S. B. — Small galls caused by insects. 



J. W. G. — The price of turntable is about 6s. (Baker, High 

 Holborn). Huxley's elementary book on Zoology, published 

 by Macmillan at about 4s. 6d. ; and Cooke's " Structural 

 Botany" (Hardwicke, Is.). 



A. H. — We did not deny the existence of a large Octopus 

 (see Science-Gossip, 1865, p. 50, ''man-suckers''); it is 

 simply asserted that there is no such thing in nature as the 

 " Devil-fish " of Victor Hugo, which is as much a romance as 

 a griffin, or a centaur, being a compound of several creatures. 



H. M. — Put in a piece of green sea- weed, and don't change 

 the water at all; it should never require it, if properly 

 balanced. 



W. — We could find no insects when the box reached us. 



T. P. F.— It is a fundamental rule with us not to insert 

 lists. 



A. T. B.-We answered your query under these initials in 

 our last number. 



T. P. F. (Kimbolton). — We do not pretend to insert every 

 query that we receive ; for the selection we use our own dis- 

 cretion, and must regard its exercise as one of our privileges. 



W. M. M. — A dashing communication. How would you 

 like the dashes printed? Certainly a curiosity— in its way. 



M. G. C. — Busk's " Catalogue of Polyzoa " is out of print. 

 His papers on zoophytes in consecutive volumes of the 

 Quarterly Journal of microscopical Science have not been 

 published separately. 



H. F. P. — 1. Abortive form of[crustaceous lichen. 2. Barren 

 squamulose lichen. Send truiting specimen. 3. Form of Bor- 

 rera pulverulenta. Lichens sent for identification should bear 

 apothecia. — W, C. 



T. W. — 1. Ptilotn plumosa. 2. Spnrochnux ri/losus. 



C. W. — All the plants you name are commonly found with 

 white flowers. For the principles which govern variation in 

 colour, see Balfour's " Manual of Botany," pp. 326-329. 



J. G. S. — What dried plants ? — Mosses, algae, lichens, or 

 flowering plants ? Try Wheldon's, Great Queen Street, W.C.
