HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORHESPONDENTS. 



All communications relative to advertisements, post-office 

 orders, and orders for the supply of this Jonmal, should be 

 addressed to the Pltblishkii. AU contributions, books, 

 and pamphlets for the Editor should be sent to 192, 

 Piccadilly, London, W. To avoid disappointment, contri- 

 butions should not be received later than the 15th of each 

 month. No notice whatever ran be taken of communica- 

 tions which do not contain the name and address of the 

 writer,not necessarilv for publication, if desired to be with- 

 held. We do not undertake to answer any queries not 

 specially connected with Natural History, in accordance 

 with our acceptance of that term ; nor can we answer 

 queries which might be solved by the correspondent by an 

 appeal to any elementary book on the subject. We are 

 always prepared to accept queries of a critical nature, and 

 to publish the replies, provided some of our readers, besides 

 the querist, are likely to be interested in them. We do not 

 undertake to return rejected manuscripts unless sufficient 

 stamps are enclosed to cover the return postage Neither 

 can we promise to refer to cr return any manuscript after 

 one month from the date of its receipt. All microscopical 

 drawings intended frr publication should have annexed 

 thereto the powers employed, or the extent of enlargement, 

 indicated in diameters (thus: x 320 diameters). Communi- 

 cations intended for publication should oe written on one 

 side of the paper only, and all scientific names, and names of 

 places and individuals, should be as legible as possible. 

 Wherever scientific names or technicalities are employed, it 

 is hoped that the common names will accompany them. 

 Lists or tables are inadmissible under any circumstances. 

 Those of the popular names of British plants and animals 

 are retained and registered for publication when suffi- 

 ciently complete for that purpose, in whatever form may 

 then be decided upon. Address. No. 192, Piccadilly, 



LONDON.W. 



E. F. B.— The larva found crawling on the pavement is 

 that of a Telephortis (Soldier-beetle), either T. fuscus 01 T. 

 rusticus. It is very carnivorous. 



J. M. H.— Young larvje of the Burnet Moth, which were 

 hatched and died soon afterwards. 



W. B. S.— Next mcnth. 



R. V. T.— Mosses. 1. Tlagiothccium elegans ; 2. Tricho- 

 stomum Uttorale ; 3. Bryum atropurpureum, with B. inter- 

 medium, — R. B. 



A Constant Reader asks whether Stephens really in- 

 serted in his " Illustrations of British Entomology," the six 

 orders of Diptera, Horaaloptera, Aphaniptera, Aptera, 

 Hemiptera, and Homoptera ? [In reply we beg to state, that 

 the orders named were not included in Stephens's "Illus- 

 trations," except a few plates of Diptera, with descriptions 

 of the species at the end of the work.] 



S. A. D.— A great deal is left to taste in the arrangement of 

 dried plants. You can fasten them by thin slips of paper 

 gummed at each end, which may be carried across the fruit- 

 stalks of the mosses. More than one specimen of the same 

 moss, or more than one species of the same genus, may be 

 mounted on the same sheet, if there is space enough. We 

 don't know there is any particular rule as to their separation 

 of the genera. Have them to succeed each other in their allied 

 order, as you will find them in all good works on muscology. 

 Will A. E. M. kindly communicate his address to the 

 Editor ? 



P. A.— Obsidian, or " Volcanic glass," a peculiar igneous 

 rock, whose appearance is due to the rate at which it cooled. 

 T. Johnson.— Seeds cf common Goosefoot {Galium 

 aparine). 



H. J.— The shells sent are, 1. Littorina riidis ; 2. Tellina 

 JSallhica, a shell especially abundant in the Baltic and 

 German Ocean. 



H. Gilbert.— The growths attached to confervse on the 

 slide sent are diatoms, Gompho7iema tenellum. — F. K. 



J. B. L.— The fungus on the leaf of Chctrophyllum temulum 

 is a Sphceropsis. 



Rev. G. Pi.vder.— Not insects' eggs at all, but a fungus, a 

 Nectria, probably Nectria Cinnaharina. The spores, which 

 are present in great quantities, will determine the species. 



J. G. sends plants with yellow flowers found on sandhills, 

 and having excrescences full of larvK, on which sparrows 

 feed greedily. The excrescences, or galls, are produced by 

 Aula.r Sabaudi. Hartig^, one of the Cynipidse. The gall is many- 

 celled, and probably would produce twenty or thirty flies in 

 the spring. The plant is either Hieracium sabaudum, or 

 H. umbellatum, on both cf which the Aulax occurs. 



Philip Barker.— You will find all the information you re- 

 quire concerning olyect-glasses and angular aperture in the 

 last volume of the Microscopical Journal. 



J. P. — 1. Foa subctrrulea ; an alpine, or starved variety of P. 

 jiriitensis. 2. The supposed Jti»cus is really part of two 

 plants, one resembling a variety of I'oa nemoralie, the other 

 a portion of Scirjius.
