HARD WICKE 'S SCIE NCE - G OSSIP. 



NOTICES TO CORRESPONDENTS. 



To Subscribers.— The compilation of the Classified Index 

 of the last twelve volumes of Science-Gossip has proved a 

 more difficult and painstaking task than we at first imagined. 

 It is now in a forward state of preparation, and we crave a 

 little grace from our numerous correspondents, who have 

 already applied for it. 



To Correspondents and Exch.\ngers. — As we now 

 publish Science-Uossii" at least a week earlier than hereto- 

 fore, we cannot possibly insert in the following number any 

 communications which reach us later than the 8th of the 

 previous month. 



A. W. S.— Many thanks for your valuable .suggestion. The 

 point you note had not occurred to us before ; but it shall be 

 attended to henceforth. 



F. C. S. — We believe the "Science-Gossip Section-Ma- 

 chine " can be obtained from Mr. Walter White, Litcham, 

 Norfolk. 



H. J. Ryder.— The price of the "London Catalogue" 

 (which may be had at 192, Piccadilly) is sixpence. 



I.. R. R. — The "pinky stone" is a fragment of calcite 

 (crj'stallized carbonate of lime), coloured with a small quantity 

 of iron o.\ide. 



T. Merrvfield.— One of the best trees to grow in towns is 

 .undoubtedly the Oriental Plane. We are surprised that it is 

 not more cultivated, under such conditions, than it is ; for it 

 ■would grow, we believe, even in our manufacturing towns. If 

 that man is a public benefactor who makes "two blades of 

 grass to grow where only one grew before," what shall we say 

 of him who makes a tree to grow where none grew before ? 



S. E. M.— Your plants are : i. the Viper's Bugloss {Echiutn 

 -i'nlgarc ; 2. the Nodding Marigold (Bidens cermia); and 

 3. the celery-leaved Buttercup {Rannnculits sceleratiis). 



Rorert Tetlow (Leeds).— Get Woodward's " Geology of 

 England and Wales," published by Longmans & Co., at, we 

 believe, 14s. 



W. Bradley.- The objects you mention as imbedded in 

 orange and apple pee! are doubtless the pupa-cases of Ccratites 

 citripcrda. 



T. B.— The "mineral" you enclosed is a fragment of carboni- 

 ferous limestone, land the fossils imbedded are corals [Lithostro- 

 tion sociale), one of the commonest and most characteristic of 

 the carboniferous beds. 



H.M.M.'VPLESON. — Accept our thanks for your kindly courtesy. 



J. B, Johnson. — If your correspondent will send the mosses 

 you refer to, we will do our best to have them named, if they 

 are in a fit state to be authoritatively identified. 



C. H. S.— For dressing skins see Swainson's treatise on 

 Taxidermy. 



To Correspondents. — Our best thanks are due to numerous 

 corre.spondents for hints and suggestions all intended for the 

 improvement of our magazine. As far as possible, we shall 

 avail our.selves of them. 



R. Middleton. — We are sorry to say the specimen of a longi- 

 corn beetle was much too imperfect to identify. Send us a perfect 

 .specimen. We cannot undertake to give names of any imper- 

 fect specimens of natural history objects, and unfortunately we 

 are usually treated to these, on account of people not likely 

 to send their best objects. 



S. E. H. — Your coloured drawing of a fungus is evidently 

 that of Agarictis lactnarius. 



H. E. Forrest. — You had better get " Half-Hours at the 

 Seaside," price 4s., where you will find all your queries 

 answered much more fully than we have space for, as they are 

 only very elementary questions. No. 3 is a frond of a red sea- 

 weed {Dflesseria), and the "little cells" you speak of are tho.se 

 of a Polyzoon called Mcmbrajiifora. 



A. K. L.AST. — We have never heard it authoritatively stated 

 who was the author of " Vestiges of Creation." It was 

 generally laid to the door of the late George Combe. For the 

 second query consult Bell's " British Quadrupeds." 



W. J. v.. Junior. — Science-Gossip is generally published 

 on the 25th of the month. Your most expeditious way to get 

 it would be to have it .sent directly from the publishers.
