HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



H. J. McG. — Your plants are, — No. 1, Erodium cicufnrium ; 

 No. 2, Spergula nrvensis. 



O. Bates. — The shrub from near Abergele is Garrya ellip- 

 tica.—J. F. R. 



A. C. — Yourplant, called the " Snowdrop-tree," is doubtless 

 Symphdria racemnsa, or " St. Peter's wort," a native of North 

 America. A good elementary book on Botany i-> that of 

 Professor Oliver, or Masters's " Botany for Beginners." — 

 J. F. ft. 



J. Platt. — Your fossils obtained from the gravel pit were 

 not vegetable, but animal. Both are fossil corals, of carbon- 

 iferous age, both of them Lithostrntion. 



J. L. — Get Wood's "Insects at Home." It not only contains 

 figures of the various insects you name, but gives popular 

 and trustworthy accounts of them. 



G.W. B. — The diatoraaceous deposit described by Ehrenberg 

 as Bermuda tripoli was long supposed to have come from the 

 Bermuda Islands. Mr. G. Norman, of Hull, found that it 

 came from New Nottingham, U. S., near which is a township 

 or hundred called Bermuda. Professor Bailey seems to have 

 sent Ehrenberg a sample, labelled Bermuda tripoli. It was 

 probably sold as a polishing powder under that name, just as 

 one of the Irish subpeat deposits was locally known as "Lord 

 Roden's Plate-powder." I fear the New Nottingham deposit 

 cannot be purchased here, but I have no doubt that some 

 American microscopist would be able to supply a small quan- 

 tity of it.— F. K. 



Fossil Tbeth. — Fig. 57, in last number of Pcievce-Gossip, 

 was printed upside down. We simply mention this that the 

 mistake may not mislead any student. 



W. K. G. — You will find a good deal of information respect- 

 ing the Old Red Sandstone fossils of Scotland in Ray Lankes- 

 ter's monograph on Devonian Fishes, published by the 

 Paleeontographical Society ; in Hugh Miller's " Old Red 

 Sandstone," " Footprints of the Creator," &c. ; and figures of 

 fossils in Devonian strata elsewhere, in Murchison's" Siluria," 

 Geikie and Jukes's" Geology," Taylor's" Geological Stories," 

 &c. 



T. E. Mason. — Your letter has been forwarded. You would 

 find no difficulty in procuring diatomaceous material through 

 our Exchange column, if you have anything to offer for it. 



H. W. Krusk, of 2, Portland-place, Southtown, Great 

 Yarmouth, kindly offers to assist any of the Science-Gossip 

 marine aquarium-keepers in obtaining salt water, if the latter 

 are willing tn pay the cost of transmission. 

 H. T. G. — Yourplant is Veronica Buxbaumii. 

 H. O. — Whitaker's " Geology of the London Basin," which 

 forms one of the volumes published by Government, under 

 the direction of the Geological Survey, will give you all the 

 information you seek relative to the depths of the deeper 

 weUs in and about London, and the strata through which they 

 are sunk. 



P. S. E. — You will find the differences (which are very g:reat) 

 between the Hydrozoa and the Polyzoa in any good manual 

 of zoology. 



J. LuMSDEN.— Your mosses are, — 3, Dicranella cerviculaia ; 



4, Sypnum purum ; 5, Sphaf^num cuspidatum. No. 2, the 



supposed "Coralline," is a seaweed, called Corallina officinalis. 



E. W. — Yo\irino''se%dLTe,— l,Funariahygrometrica; 2,Dicra- 



nella varia. — R. B. 



E. V. Pike. — Kirby & Spence's " Entomology "is published 

 by Longmans & Co , at about 5s. For a beginner, Newman's 

 •' British Moths" and "British Butterflies," would be much 

 better. The price is not very great. 



J. DuTTON.— Stark's "History of British Mosses," published 

 by Lovell Reeve it Co., would be the best book you could 

 obtain. The price is, we believe, ]0s. 6d. 



E. Thomas. — It is not at all a rare matter for the Peacock 

 butterfly to be .seen on fine days in February, inasmuch as it 

 hybernates during the winter, and is warmed into life by the 

 returning heat of the sun. 



S. A. Brbnan. — Fhnllus esnulentug is identical with Mor- 

 chella etcuienta. See Cooke's " Handbook of British Fungi," 

 fig. 656. 



J. C. MuiB.— We are sorry to say your specimens of Isoetes 

 hystrix never reached us. 



R. Taylor, referring to Tate's "Manual of British Molluscs," 

 which gives the habitat of P/rt«or6is lineatus as "near Lon- 

 don," wants to know the exact locality. Will some one help 

 him to it ? 



Henry Gould.— Yonr specimen is not a clustercup, but so 

 nearly resembles Mcidium that it was formerly called Vredo 

 rtridiiformis. It is now known as Trichobasis petroselini. 

 The plant on which you have found it is the Stnyrnium olus- 

 ntrum.—M. C. C. 



J. G. — You will find a good direction of how to cut sections 

 of coal in page 87 of Science-Gossip, volume for 1872, and a 

 further account, by Mr. E. T. Newton, on psge 19, volume 

 lor 1873. 



C. C. Underwood. — Your micro fungus on leaf of Date- 

 palm is Graphirila phoenicis, figured in Cooke's " Handbook 

 of British Fungi," fig. 221. 



E. L.— The snail shell is that of the " Apple snail " (Helix 

 pomatia), our largest species. The mineral is carbonste of 

 lime (calcite), deposited as stalactite.
