HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



To Correspondents and Exchangers.— As we now 

 publiBh Science-Gossip 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 each 

 month. __^_ 



E. Lovett.— Many thanks for the slide. 



E. W. A. — Either some joke or some mistake has been per- 

 petrated, for the flowers, " all from this neighbourhood," 

 consisted of wheat, oats, roses, geraniums, and maiden-hair 

 ferns ! 



H. A. S.— The "minute black spots" on the chalk sur- 

 rounding flints are filmy deposits of oxide of manganese. 



James W. R. (Manchester).— Get Lankester's" Half-Hours 

 with the Microscope," with chapter on Polarization by 

 F. Kitton. 



S. A. B.— The galls on the hawthorn are produced by the 

 puncturing of the bark by a species of Cynips. 



H. R. M.— Smee's " My Garden"; Burbidge's "Domestic 

 Floriculture " ; and Hensley's " Hand-book of Trees, Shrubs, 

 and Herbaceous Plants," will, any of them, give you the 

 information you seek. 



A. B.— Thanks for the interesting specimen of a mon- 

 strosity in Medicago. 



G. R. Vine.— The specimens of macrospores of Lepido- 

 dendron are thankfully accepted, as would be any other 

 similar objects. We never heard of their being found under 

 such conditions before. Send us a short account of them. 



M. Mudie. — Your fungi arrived in such a state of decom- 

 position that it was impossible to identify them. A new 

 edition of Cooke's " British Fungi," with coloured plates, 

 will shortly be published by Hardwicke & Bogue, iy2, 

 Piccadilly. 



Enquirer. — We are not aware of the existence of any 

 special scientific book club. The best work is Nicholson's 

 "Manual of Palaeontology," published by Blackwood. 



R. Booty. — The specimens are: 1. Cardium echinatum; 

 2. Pecten dubius ; 3. Hydrobia ; 4. Cyprea Europeu ; and, 5. 

 a species of Bulla. 



Permian.— Among the best books on Geology are Lyell's 

 " Student's Manual ";Geikie's edition of Juke's "Manual"; 

 Green's " Manual '' (1st vol. on Physical Geology only) ; and 

 Tate's edition of Portlock's " Manual." The best work on 

 Palaeontology is Prof. Nicholson's "Manual.'' The only 

 special work on the Permian formation is in German, by 

 Prof. Geinitz, on the " Dyas." The book by Lyell you men- 

 tion is so |largely added to in the later editions, that it is 

 hardly worth while putting it in the hands of a student who 

 wants to gain time. 



H. M. C. A.— The plant will be named in our next issue. 



W. A. C— Your tern is a young specimen of Polystichum 

 lonchitis. 



M. F. — The specimens are : Corallina officinalis (a sea-weed 

 which secretes lime, and is usually of a pinky-white colour), 

 and a dried specimen of a zoophyte {Tubularia indivisa). 



J. J. V. — The flower is that of the Soap-wort (Sapunaria 

 officinalis) .
