HARDWICKE'S SCIENCE-GOSSIP. 



[June 1, 1S67. 



NOTICES TO CORRESPONDENTS. 



■p S, k. It is not our province to name packets of objects ; 



we really cannot afford the time to do for others what, with 

 a little care, they could do for themselves. No. 1 is Dadaleu 

 quercina. , , , 



E M. H.— No. 1. Yes! it will do so. 2. The only book for 

 a beginner is Lindsay's " British Lichens," Routledge & Co. 

 3. It is impossible to say. 



G. G. — The fungus is Polyporus versicolor. 



A (Dartmouth) could name his Corallines with the aid of 

 Johnstone's " Zoophytes," published by Van Voorst. His 

 No. 2 is Corallina officinalis. 



H. H. (Fairy Villa).— It is not very easy to discover what 

 you require. If we understand you correctly, it is that you 

 desire to know just those problems which are continually 

 puzzling men of science, and for the discussion of which our 

 columns are unsuited. ... <■ 



J G desires some certain method of ridding his house of 

 cockroaches. We have heard of many remedies, but never 

 had any occasion for making the experiment. See Science- 

 Gossip, 1865, pp. 42, 66. 



L. A. G.— Is it the thread-worm (Gordius aqualwus) > See 

 Science-Gossip, 1865, pp. 107, 197. 



R. T. A.— The slide contained no organic form whatever. 



F. S. F. (Plymouth).— We regret that we can give no in- 

 formation of the process beyond the extract quoted. 



W. W.— R. W.-We never attempt to name objects from 

 description only. 



The Nightingale.— Science-Gossip, bottom of page 112, 

 for " March," in both instances read " April."— L. S. 



J. L.— J. H. W.— Messrs. Hooper & Co., Covent Garden, 

 or Mr. Sim, of Foot's Cray, Kent, or any other nursery- 

 man growing ferns extensively, would furnish the prices of 

 any of the ferns named in the article alluded to, upon applica- 

 tion by letter enclosing stamp. 



W. W. S.— Mix glycerine and spirit, says " Davis on Mount- 

 ing," p. 17. We use gum-tragacanth, mixed with gum- 

 arabic or calcined starch, sometimes called British gum. 



W. D. R.— No book containing descriptions of the species 

 of British Coleoptera has been published since " Stephens' 

 Manual," and that, of course, is now very imperfect. 



r, w.— There is no cheap work on Diatoms. We have 

 given in Science-Gossip instructions for mounting crystals. 



G. L.— You will find answers to all your queries in " Davis 

 on Mounting," &c. price half-a-crown. 



B. L. W.— We cannot inform you ; probably the result of a 

 wound. 



J. G. T.— Patience and plenty of water works wonders. 



D. S.— It is sometimes called the " great saw-fly." 



J. B.— Many larger specimens. It might possibly have 

 occupied the matrix of a femoral bone, but this is speculation. 



Lizzie should remember how much easier it is to ask ques- 

 tions than to answer them. 



W. F.— We have already given full instructions for cleaning 

 Fossil Diatomacese. 



E. F. M.— Very like a " canard." 



S. C. surely must have made a mistake. Was it the Barn 

 owl, and not the Snowy owl? 



E. C. J.— White's " Popular History of the Crustacea." 

 London : Routledge. Price 7s. 6d. The malformation of the 

 daisy is not uncommon. 



British Insects.— The printed lists of British Insects, 

 entitled " A Catalogue of British Insects in all the Orders," by 

 the Rev. F. O. Morris, B.A., is at length published. 



Mrs. K— T. H.— A. Dartmouth.— D. W.— W. R.— It is im- 

 possible for us to name all the specimens of mosses, lichens, 

 zoophytes, &c, which are continually sent us, notwithstand- 

 ing our repeated protests, in parcel-; of from six to twelve 

 species from a single correspondent. Henceforth, therefore, 

 whatever number may be sent, we shall only name one out of 

 each packet. 



W. D.— F. W. — We only insert in our exchange list objects 

 of Natural History for which other like objects are required. 

 Other exchanges may be inserted as advertisements, the 

 charge for which may be learnt from the Publisher. 



W. F. H.— Any water-mites are desired. The mollusc is a 

 common species — Cyclostoma elegans. 



W. R. — No. 1 is Climacium dendroides. 



D. W. Skye.— No. 8, Mercurialis perennis. 



H. M. (Birmingham).— It is Julus terrestris, not an in- 

 habitant of the water, but having got into the spout of the 

 pump came out with the water. 



W. M.— Please to refer to page 96 of Science-Gossip. It 

 is carelessness to ask a question which has only just been 

 answered in two consecutive numbers. 



J. S. K. — No English work contains coloured figures of all 

 the British Lepidoptera. The nearest approach is Wood's 

 Index Entomologicus. Nor is there a work in which British 

 Lichens are all figured. For British Mosses, see Wilson's 

 " Bryologia Britannica." 



F. H.-We really know of no book " fuller " than that 

 named. Its want can only be supplied by several books in 

 different branches. 



B. (Manchester).— Any large bottle warehouse, or dealer in 

 druggists' sundries, in London. Surely also in Manchester or 

 Liverpool such things can be obtained. If not, the dimensions 

 must be sent to some friend in London, who may call upon us 

 for advice. 



J. B. S.— Davis on Mounting Microscopic Objects, page 80. 



P. P., who inquired in March number for Bermuda Earth, 

 will please to furnish name and address to the Editor. 



Quarterly Journal of Microscopical Science. — Vol. 

 VII., for 1859, wanted. A good price will be given. Ad- 

 dress, the Editor of Science-Gossip. 



C. D. H.— Unfortunately your plant was too much shrivelled 

 to determine with certainty. 



B. T.— No. 1 is Scatophaga stercoraria (Order, Diptera). 

 No. 2 is Chrysopa perla (Order, Neuroptera).—F. W. 



Deodara.— R. B. states that the age of the tree alluded to 

 in our last is only thirty years.
