HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



E. L. — We hart no solution to offer. 



J. B.— The Italian fungus-stone is mentioned by Dr. Bad- 

 ham, and you give no additional information. 



M. D. P. wants to know of any other birds (except pigeons) 

 that feed their young in the same manner as the canary. 



B. W. P.— Probably a boraginaceous plant, but we should 

 not attempt to name it from a fragment of a leaf. 



H. M.-We have already given instructions for cleaning 

 diatoms, in early volumes of S.-G. No. I is Coleosporium 

 pingue. No. 2. Junta rubens. 



W. G.— The injects on bark are Adelges corticulis, often 

 very injurious to pine-trees. 



S. h.— We make it a rule not to recommend any particular 

 tradesman or firm. Your first query you will find answered 

 in treatises on bleaching. We do not remember who is the 

 publisher of " Solly's Analysis of Plants." 



H. A.— -Lots of white mice. 



J. H.— You will find some communications on the spider 

 swallowing its web in our first volume. 



E. G.— Undoubtedly the plants spring up from dormant 

 seeds, which may vegetate alter being buried very many 

 years. 



H. C. H. — Vaceinium vitis idma. Theother subject is wholly 

 a matter of taste, for which no law can be given. 



J. B. D. will find Cooke's " Manual of Structural Botany" 

 (one shilling), and "Manual of Botanic Terms" (half a 

 crown), published by Hardwicke, 192, Piccadilly, just what 

 he asks for. 



r. G.— No manual of Coleoptera has been published since 

 Stephens's, which is very much out of date. 



H. A. S.— Not a fern at all, but a fungus on leaf of betony, 

 Puccinia Bet'micte. 



W. A. C— The address being given, you had better apply 

 direct, as we object to advertising prices. 



E. L. (Hull).— Use dammar dissolved in benzole in the 

 same way as Canada balsam is used. Experience will test 

 its advantages. We always use it in preference to balsam, as 

 no heat is required, and it soon becomes hard. 



A. R. G. inquires for a Field Club in S.W. London, for 

 Kingston, Wimbledon, and the neighbourhood. We know of 

 none. 



W. G.— The Uredo on rose is not the common rose-rust, 

 but apparently Coleosporium pingue. 



W. W. H.— The hairs from the stipes of an exotic fern, pro- 

 bably a Cibotium. 



W. C. P. — We cannot answer your question. The means 

 were at your hands, by examining microscopically, or testing 

 the water, to discover the cause. 



J. H.— S< iknck-Gossip is now generally ready two or three 

 d*ys before the first of the month. 



G. D. — We do not remember any detailed account of the 

 /hemical and physiological effects of viper poison except in 

 " Christisou on Poisons." 



F. G. complains that borax will not destroy cockroaches. 

 Similar testimony is given in the present number. Beetles 

 are insects, of course, and thequestion, " Do insects grow? " 

 was discussed in an early volume of S.-G. 



R. H. W.— We know of no work containing the desired in- 

 formation on dry rot. Several communications are scattered 

 through the volumes of the " Gardener's Chronicle." 



W. D. R.-We should think that Grindon's " British and 

 Garden Botany " (Routledge), or Bentham's "Handbook of 

 the English Flora" (Reeve), would suit you. 



Miss G.— The insect is a water mite: it belongs to Acarini 

 and the genus Hydrachne ; the growth on Vulimeria is Con- 

 ferva. 



J. S.— It is Trichobasis compositarum ; the fly is Chrysis 

 ignita. 



W. D. R.— No. 1 is Php Hob ins argentatus, Linn.; No. 2 is 

 Sitnnes lineatus, Linn. — E. C. R. 



H. M.— Possibly a new volume on insects published by 

 Lovell Reeve & Co. It is difficult to recommend a small 

 volume for such a wide range of subjects.

 by the same individual. The maximum length (except for
