HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



E. W.— The larva is that of Meloe angusticoUis. For a full 

 account of this and other parasites on the bee, see article in 

 SciBNCR-Gossip for 1870, pages 2 and 3, entitled " The Para- 

 sites of the Honey Bee," by Dr. A. S. Packard. 



Enquirer.— We have received the piece of pnmmed paper 

 said to contain specimens of mites. We do not undertake to 

 name specimens unless sent in a fit state for examination. 

 We cannot ask those gentlemen (all of whom are authorities 

 in their special departments) who kindly undertake to assist 

 us, to prepare specimens for examination. It is also neces- 

 sary that the sender should furnish us with all the informa- 

 tion as to habitat, &c., he is able to give. We are always 

 anxious to assist the student in natural history, but he must 

 also put his own shoulder to the wheel. 



L. T.— The moss is the commonest that grows, the Screw 

 Wall-moss {Turlulamuralis). 



Kkw Subscriber.— Answer next month. 



Ignoramus.— The small larvie- cases found on espalier 

 apple-tree are those of Culeophas anutipentmlla. 



A. L., Scarborough.— You will find Stark's " British Moss- 

 es" (Lovell Reeve & Co.), price 7s- 6d., a capital introduc- 

 tory book to the study of mosse.o, containing a good number 

 of coloured illustrations. 



R. De I>.— The jelly-like substance adhering to leaves is 

 probably the ova of some species of shell-fish, perhaps of 

 Limnea. It is not the common stickleback, which builds a 

 nest. 



Richard Smith, Belper. — Tissues may be placed in the 

 carmine staining fluid as soon as cut, unless maceration in 

 glycerine is requisite to soften them. You will find all the in- 

 formation required for staining the various tissues in Dr. 

 Beales's" How to work with the Microscope." 



Unscientific Astronomer.— There is a society called the 

 " Observing Astronomical Society," different from the Royal 

 Astronomical Society. The Hon. Secretary's name is Wil- 

 liam F. Denning, from whom all information may be obtained. 

 — Address Messrs. Wyman, 74, Great Queen Street, London. 



A. H. A., Liverpool.— The Podurpe in the piece of wall-paper 

 are Achortttes purpurescens, common in damp places.— 

 r. J. McI. 



B. E. F. — Mineralogy is now included as part of chemistry, 

 rather than of geology, as was formerly the case. There can 

 he no doubt that tlie connection between the two former is 

 far more natural, although mineralogy is of great service to 

 the geologist, especially in his lithological investigations. 



Roy.- You will find a full account of the natural history 

 position, functions, and habits of the sponges in Nicholson's 

 " Advanced Text-book of Zoology," or in the " Manual of 

 Zoology," vol. i., by the same author. 



A. Smith. — The parcel of grass sent is the Sweet-scented 

 \ernaX Gr&is, {Antho.ranthum odoratum). It is the presence of 

 this grass which gives the well known scent to newly-mown 

 hay. 



A. J. D.— A capital chapter on " Mimicry " will be found in 

 Wallace's " Contributions to the Theory of Natural Selection." 

 Bates first broached the doctrine in his " Naturalist on the 

 Amazon." See article in last number of the Entomological 

 Magazine on mimicry in insects. 



.1. B.—Hypnum commutatttm : a little Anodus will be ac- 

 ceptable.—/}. B.
