HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



E. H. — Your article is in type, and will appear in due 

 course. 



B. Belfield. — Your specimen of female fern (Athyriutn 

 filix-fcemina) is very remarkable. It answers to the descrip- 

 tion of the \SiT. trifidum, in Newman's "History of British 

 Ferns," better than to any other, and we have no doubt this 

 is the variety the specimen belongs to. 



J. Aitkin. — The white crust which you described as so 

 abundant nn the bark of beech-trees, and of which a speci- 

 men was forwarded, is not of veg:etable origin, and therefore 

 not a fungus or lichen. It is of animal origin, formed of a 

 species of Cj/nj'pg, like the " apple-blight.'" At one time it 

 was considered to be a fungus, and was then named Psilonia 

 nivea, 



R. Stavden.— Your drawing is that of the Great Saw-fly 

 {Urocerat giga$). 



Mrs. W. — You had better consult a practical nurseryman 

 about the roots of your cherry-trees. His experience will at 

 once lead him to say what you had best do to arrest the 

 attacks of the insects anU fungi. 



C. L. — Read the paperon "The Formation of Chlorophyll," 

 in the November number of H.-G., for information as to 

 whether sunlight affects a fire You will there find experi- 

 ments related which prove that it does. 



R- W.— Genuine thanks for your hints as to the matter on 

 our last page. 



T. L. — Your specimen is evidently a stunted form of Deles- 

 teria atata.—W. H. G. 



J. V. — Your specimen of Bryopsis plumosa, with a so-called 

 green parasitic growth attached, was forwarded to one of our 

 best algologists for identification. He writes, " It looks like 

 half a dozen different things, but it is so muddled together 

 and so interwoven that I hardly know what to say of it. I 

 have given what time I had to spare to it, and believe it to be 

 some abnormal or undeveloped filaments of Bryopsis plumusa. 

 I do not think it is a parasite." 



J. "P. Greelv. — The specimen inclosed was one of the 

 wire-worms, the larva of a beetle It is difficult to prescribe 

 a remedy for its af:arks. Perhaps some of our readers can, 

 and will reply. 



J. B. Da VIES. — Your fronds are undoubtedly those of 

 Lastrea cristata, var. uliginoaa, now very scarce. Pray, 

 preserve the habitat. 



H. G.— They are caused by an insect, a species of Cynipg, 

 and are known as "Oak-spangles" and "Buttons." See 

 " Half-Hours in the Green Lanes." (London: Hardwicke). 



E. W. — The fern is Aspleniutn lanceolatum ; the lichen a 

 Cetraria. 



W. E. Sharp.- Your eggs never reached us. Perhaps 

 they were disposed of in the transit, unless well packed. 



J. Wilson. — The parasites on the badger were Tricltodectes 

 crastug, Denny's "Monograph," plate 17, fig. 3. It is dis- 

 tinguished by the notch on the top of its head.— 7. O. W. 



J. P. B.— We are sorry that your notice reached us too late 

 fOr insertion in the December No. of Gossip. 



J. M.— We shall be happy to get your Mosses named for 

 you if you will forward them (properly packed) to our office.

 ficB — I think It is undescribed. — M. C. C.
