HARDWICKE'S SCIENCE-GOSSIP. 



[April 1, 186S. 



NOTICES TO CORRESPONDENTS. 



E. A. W. — The fossils are Avicula eehirutta, Sowerby, 

 Cornbrash Kidlington, Oxon, and Pecten urcuatus, Sowerby, 

 Great Oolite, near Great Barford, Oxon.— if. W. 



C. P. C. — The fungus is Polyporus adustus. — Fr. 



J. R.— No. 3 is Anthroceru fitipendula. The rest we would 

 not attempt to name from such fragments. 



Paul and X. Z. are reminded that all anonymous com- 

 munications are at once consigned to the waste paper 

 basket. 



E. H. — Your beetle is Sylesinus crenntus (Fab.), a wood- 

 feeder often destructive to ash trees, and abundant where it 

 occurs, but not generally common. — E. C. R. 



A. A. — We never experimented on the flight of bees. 

 W. N.— The American Naturalist is Is. 6d., and may be had 

 of Triibner & Co., Paternoster Row. 

 H. C. — Not a question of an eligible character. 



J. C. C. — Our advice is, read De Quincey's " Confessions of 

 an English Opium Eater," and leave experiments alone. 



J. W. G. — To preserve fungi, see " British Fungi," pub- 

 lished by R. Hardwicke. The Diatomaceous earths may be 

 had on application to the Editor, enclosing four good mounted 

 objects. 



L. H. F. — The " flea cage" was made to order. 



G. R. R.— The Fairy Shrimp is almost always to be found 

 in a diity little pond on Blackheath. 



M. C. P.— Inquire of Mr. W. Pamplin, Llanderfel, near 

 Corwen, Merionethshire. 



Tracks on the Giants. — We have received several com- 

 munications on this subject, but from our experience of the 

 Unity Controversy must be excused if we decline to permit 

 another, and hope that our correspondent F. A. A. w r ill quit 

 such controversial topics. 



W. F. — We do not regard Autographs as objects of Natural 

 History, 



F. S.— The moth is " The Herald," Scoliupteryx Ubatrix. 



G. (Hehton). — We cannot reprint the six or seven pages of 

 Dr. Herepath's description of his process of manufacturing 

 his crystals of Herepathite ; our correspondent must consult 

 the 2nd volume of the " Journal of Microscopical Science," 

 p. 83. 



E. J. R. — We do not insert books in our Exchange column. 



W. C. J. F. — It is a mistake, as mentioned in our notice. 



M. G. F. — Much depends upon taste ; cardboard boxes with 

 glass tops are now much used. The shells are placed upon 

 wadding. Wash your " mouldy " shells. 



R. V. T. — The moss is Burtramia pomi/ormis. — R. B. 

 W. A. — No. 1. Dicranell'i varia. 2. Pottiatruneata. 3.Tor- 

 tulu unguiculata. 4. Hypnum rutabulum. — R. B. 



J. F. — We do not know the address. All artists are not 

 naturalists or astronomers. We do not see that your criti- 

 cism is correct. 



O. P. — We can see disadvantages in your tin forceps, and 

 no advantages, not even cheapness. You are wrong in " from 

 one to three shillings " being the price of common brass 

 forceps. Acari are found in other than damaged brown sugar 

 by those who use their eyes. 



A. L. L. — We should think it much more probable that if 

 the story were traced to its source, it would be found to be 

 a " gull for gullible people." 



A. A. A. — Do you know " Bechstein's Cage Birds," or 

 " Beeton's Home Pets" ? Fortune's " Tea Districts of China " 

 is perhaps what you require, or Porter's "Tropical Agri- 

 culturist." 



Seaweeds (name and address mislaid). — No. 1. Batracho- 

 spermum (early stage?). No. 3. Gemellaria loriculata (a 

 zoophyte). — No 4. Polysiphonia elonguta (spring condition). 

 — W. H. G. 



W. H. G.— Not uncommon. It is a caulescent form of the 

 common primrose. 



T. P. B. — Your toad story requires, what so many of these 

 reports require, strict investigation before publication. It 

 can do no good to add another without unimpeachable proofs 

 of veracity. 



R. M. B. — " Ootheca Wolleyana" is published by Van 

 "Voorst (coloured). Part I., Royal 8vo., 31s. 6d. The only 

 complete work on British Mosses is Wilson's Bryologia 

 Britannica (coloured;. Price four guineas (Longmans), but 

 this requires revision. 



T. H. H.— The moths are (no numbers) Xylophasia rurea, 

 var. combust a, and Hadena Pisi. — H. G. K. 



K. W.— In " Our Reptiles," published by R. Hardwicke, 192, 

 Piccadilly, price 6s.
