HARDWICKE'S S C lEN CE- GOS SIP. 



NOTICES TO CORRESPONDENTS. 



T. Swallow.— Your mosses are: 1. Hiipnum velutiyium, 



.Dicranetla heterdmnlla. and 3. Luphocola IMentata. Get 

 Cooke's " British Repaticse," with figures, price 4d., or the 

 parts now issuing of Carringfton's "British Hepaticse," both 

 published by Hardwicke, 19-'. Piccadilly.— R. B. 



Gbmixi. — We are not aware of any bird equal to the task of 

 clearing away ants. Try sprinkling with a little carbolic acid. 



Charles Dickik.— To clear a room of cockroaches place a 

 shallow plate full of beer on the floor at night. As these 

 insects are not Good Templars, they rush in large numbers to 

 the beer, and thus share the fate of the Duke of Clarence. 



H. G. W. A.— The Arachnid found in the grass to which you 

 refer answers in its description to the Dog-tick {Ixodes 

 ricinus). 



G. R. W.— It is not uncommon for the spore-bearing fronds 

 of young specimens of the flowering ferns {Osmunda regalis) 

 to be converted into pinnules. 



,Ida F. T.— The malformed specimens of Corn Feverfew 

 iPyrethvum inodovum) come under what Dr. Masters, in his 

 " Vegetable Teratology," calls " excess of development." 



Horace. — The insect you inclosed was an Ichneumon 

 {Ophion). 



J. Sims.— We will do our best to obtain you a specimen of 

 Miocene lignite. Perhaps some of our readers will forward 

 us a bit from Bovey Tracey. 



A Constant Subscriber asked us to name an "inclosed 

 plant " ; but none was " inclosed." By the way, we should 

 feel obliged if our correspondents who wish to preserve their 

 incog, would adopt some other nom de plume than " Constant 

 Subscriber." 



Mrs. a.— We are sorry to say your MS. has been mislaid, 

 and is not to be found. 



Thos. Buck.— It is not uncommon for the eggs of domesti- 

 cated fowls to occur with double shells in the way you name. 

 Doubleyolked eggs are still commoner. 



H. Marshall V/aru. —Potenti/la fragoriastfum, similar 

 to Fragaria vesca, but has no runners, nerves of leaflets not 

 sunk above, and fruit very different. Hooker's " Flora of 

 the British Isles."— B. W. 



F. L. — The natural food of the larva of the common house- 

 fly {Musca domeatici) is said to be horse-dung. Conse- 

 quently, these insects are always most abundant in the 

 neighbourhood of stables, &c. 



D. BRAni.KY.— The best work on Diatomacere is that now 

 issuing in parts, by Dr. Donkin. 



Bk. Smart.— Your specimens of flint were covered with 

 a lichen called Vernicnria nitida. 



J. K. J.— The package arrived, but the glass was smashed. 



C. U. (Reigate). — Your specimen is not an Erica, but its 

 near sister, the common Ling, Calluna vulgaris. Perhaps its 

 unusually hoary foliage may have misled you into supposing 

 it to be a form of Erica tetralix. — R. 



H. E. Dent. — The specimen of Lnmium album is the pretty 

 and elegant variety, recognized as a species by some authors, 

 under the name of L. maciilatum ; other writers, on the 

 contrary, unite L. Icevigntum and L. vinrulatuin with L. 

 album, into one species. We have noticed large roots of this 

 variety in our cottage gardens. — R. 



F. R., Clapham (August number, p. 189).— Green Cater- 

 pillars. — Dust your gooseberry bushes with white hellebore 

 directly you see the caterpillars, and they will drop off dead. 

 Broad beans plantf-d in rows between the rows of gooseberry 

 bushes preserve them from blight : supposed cause is, that 

 the beans give out a great deal of carbonic acid gas.— A. F. F. 



Mrs. a. Watnev. — " Grevillea," edited by Dr. M. C. 

 Cooke, is now published quarterly, by Williams & Norgate, 

 Covent-gardon, London. 



A Constant Subscribbr (No. 2). — The flower sent, found 

 at Twickenham, is the Bloody Crane's-bill {Geranium 

 sanguineum).
