HARDWICKE'S SCIENCE-GOSSIP. 



[Dec. 1, 1869. 



NOTICES TO CORRESPONDENTS. 



D. G. W.— The Journal of Botany is published by Lovell 

 Reeve & Co., monthly. 2s. 



H. C. L. — Surely you cannot have read Mr. Wallace's 

 article on " Mimicry " in the Westminster Review, or you 

 would not think your observations new. 



A. H. — Could you not start a journal of your own, in which 

 your pugnacity would have free action? 



C. J. W. R.— It is easy enough to have your bat named 

 from the specimen. We cannot insert a long description for 

 that purpose. 



R. C.— The " Handbook of British Fungi " will be published 

 at 15s. As soon as the names of 400 subscribers are ob- 

 tained at Half a Guinea, the list will be closed. Already 

 half the number have been received. Additional names may 

 be forwarded to the Editor of Science-Gossip. 



W. W. — It is an idle and slovenly habit with some'entomo- 

 logists to write only the initial letter of generic names, and 

 should not be tolerated. 



R. M. — We do not give art advice, but for our own pur- 

 poses we use the water-colours manufactured by Brodie & 

 Middleton of Long Acre. They are cheaper considerably, and 

 quite as useful as those sold by the great " art establish- 

 ments." 



A. A. — It is undoubtedly the Humming-Bird Hawk-moth. 

 True Humming-Birds belong to the New World. 



W. H. P. — If the printers cannot decipher your names, the 

 blame must rest with the writer. 



W. H. — Polypodium vulgare, variety serratum. Lowe's 

 Ferns, plate 30.— J. G. B. 



F. W. W. — Lastrea ditatata, ordinary form.— J. G. B. 



H. R. W. — Apparently seedling of Pteris aquilina. — 

 J. G. B. 



L. M. P. — "Newman's British Moths" contains the 

 Sphinxes, but nut the Butterflies. The latter may be had 

 separately. It is not possible within the limits of a moderately 

 priced book to give the older synonyms ; some of these 

 will be found in the British Museum Catalogues of Lepi- 

 doptera. 



D. P. P. — Easily dissolved in nitric acid ; probably organic, 

 say, spores of conferva, but we cannot determine from the 

 dried dust. 



R. T. Andrews. — We wrote to the address named in your 

 " Exchange" notice, and the letter is just returned "not 

 known." Of course we have not inserted the notice. What 

 can be the motive for a " hoax " of this kind ? — not the first, 

 unfortunately, which originated from our Exchange column. 

 Injustice to our readers, we are bound to watch for the de- 

 linquents, and exclude them for the future. 



F. D., W. 0.,and G. B.— Your " Exchanges "are ineligible 

 according to our rules, by which all objects are excluded 

 which are not bond-fide natural history. 



P. E. N. — The fly is Borbovus equinut (order Diptera, tribe 

 Musettes). It is generally distributed, and abounds near 

 stables. — F. W. 



II. H. N. B.— The insect is Psorus abdominnlis (order Neu- 

 roptera, family Psocida>). It feeds on vegetable substances. — 

 F. W. 



E. D. B. — Let them alone till the warm weather of spring 

 arouses them. Reptiles require no food in winter. 



M. B.— If " M. B." sent such specimens of mounted slides 

 in exchange as we have seen from him, we are not in the 

 least surprised that he got nothing for them. In such a case 

 it would serve him right. 



Water for marine aquaria is supplied, fresh from the sea 

 daily, at 3d. per gallon, by the London and Brighton Sea- 

 water Company, 2, Albert Mansions, Victoria Street. 



J. F. C. — The objects referred to are glandular scales, 



St. E. — A volume published by the Society for Promoting 

 Christian Knowledge would suit your purpose. We forget 

 the precise title. The coloured illustrations you name are 

 pretty good. 



A. E. L.— " Mineral Statistics," published aunually by the 

 School of Mines in Jermyn Street. 



W. L. W. E.— 1. Pottia minutula. 2. Uypnum mollitscum. — 

 B. ./>. 



J. B. L. — Bryum pseudotriquetrum. — B. B. 



J. C. D. — 4. Frullania dilatata. 5. Poqonatum alo'idet. — 

 li.B. 



J. E. M. — The New Zealand mosses are Meteorium motle, 

 barren ; Eriopus cristatus, in fruit. — B. B.
