HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



•■ W. S. Thomas.— You will see by referring' to the terms 

 under which we insert Exchanges grath, that we cannot 

 allow more than three lines. Your exchange would make 

 nearly a dozen ! 



T. C. M. — The published price of Kinahan's " Handy-book 

 of Rock-names" is 4s. It may be obtained of Hardwicke, 

 192, Piccadilly. 



G. S. S. — You cannot do better than get Nicholson's " Intro- 

 ductory Text-book to Zoology," where you will find the sub- 

 jects mentioned, treated under their several heads. " Half- 

 hours by the Sea-side" (London, Hardwicke) will also 

 help you to an elementary knowledge of all you name. 



T. W. Harris, Jun.— We have no doubt you could obtain 

 the eggs, &c. of the Ailanthux from Mr. S. H. Gaskell, 

 Edgely, Stockport. See advertisement in May number of 



SCIENCE-GOSSIP. 



A. SMYTir.— We do not think it possible for the larva of 

 any insect to remain in the human stomach, especially for 

 the long periods usually assigned to such supposed cases. 



F. C. B.— Your specimen is the tufted Water Forget-me- 

 not {Myosotis ccBspitostt). 



A SuBSCRiBKR. — Anacharis alsinastrum is so common in 

 the dykes and rivers of the Eastern counties as to be a great 

 nuisance. Chura vulgaris is tolerably common in the same 

 localities, in the shallow bog-pools on commons. 



W. H. S.— The insects are the Four-spotted Ladybirds {Coc- 

 cinella quadripunctata) . 



M. A. H.— I. Plumstead Wood still exists ; it is very near 

 the Plumstead station on the North Kent Railway. 2. 

 "British Concbology," by J. Gwyn Jeffreys; Tate's "Land 

 and Fresh-water MoUusca" (Hardwicke, Piccadilly). 3. We 

 do not undertake to return specimens sent to be named. 



J. F. Baulch.— You may prevent spiders' eggs from hatch- 

 ingby placing them in an oven, or in hot water, spirits of wine, 

 or carbolic acid, but if preserved dry they will shrivel. Possibly 

 you may be able to preserve them in small glass tubes of 

 dilute carbolic acid or spirits of wine. You can obtain ento- 

 mological appliances from T. Cooke, 513, New Oxford-street, 

 London, or any professional naturalist,— Rye's " British 

 Beetles," price 10s. 6d. 



J. H. E,— The insects are Aradus depressus (2 perfect, 1 

 pupa), order Hemiptera, commonly known as "bugs."' 

 The 'rat-tailed larva" is probably that of a species of 

 Selophihis. There are many species. These larvre feed in 

 damp and muddy places, and in vegetable detritus; hence the 

 one in question was in a suitable place. — J. W. D. 



Clifton Simmonds.— Your description of the caterpillars 

 is too vague to indicate to what order of insects they belong. 

 Possibly they may be Cossus ligniperda (the Goat-moth) half 

 grown, but the crimson stripe halfway down the side does 

 not agree with that species. Can you send a specimen? — 

 C. G. B. 



E. R. wishes to know if there is a Geological Society in 

 South London, and if so, desires particulars of it. Perhaps 

 some of our readers can give the information. 



K. W.— Withering's "British Botany" is the best hand- 

 book of the British Flora arranged on the old Linncean system. 



A. G. Weld, — The eggs are commonly known as "Fairies' 

 Bracelets," and are those of the Ground Lackey [Lasiocampa 

 Neustriii) . 



R. s.— We should think that Hooker's Flora is too advanced 

 a book for you at present. Masters'" Botany for Beginners," 

 and Balfour's " Elementary Botany," or Professor Oliver's 

 " Elementary Botany '' would be better. Get Mrs. Lankester's 

 "Wild Flovs^ers worth Notice," London, Hardwicke. 



H. L. Kay. — The geranium leaf sent is really two leaves 

 that have been united along the lower edges. For a scientific 

 explanation of this and similar phenomena see Dr. Masters' 

 " Vegetable Teratology." 



J. p. G — Your specimens were the eggs of the Emperor 

 Moth (SiUurnia Cdrpini). The caterpillars have come out 

 since the parcel arrived, 



J, W. D. — The specimen is the leaf and catkin of the Goat- 

 willow C^iilix caprea). 



A. W. Field.- Your specimen is one of the suctorial worms 

 (Trematoda), or "Flukes," as they are commonly called. 

 They are parasitic in fishes and birds, but the commonest is 

 that inhabiting the livers of sheep. 



F. G, Mellish,— Your plant is a hardy plant imported into 

 thiscountry many years ago from Siberia, It is called Dielptra 

 spectahilis. 



W. O.— We always endeavour to insert answers to queries 

 in the order of priority. You have no idea of the correspond- 

 ence which often takes place before some specimens can be 

 named. Some of the most eminent naturalists of the day 

 assist us, and we cannot do less than wait their own time in 

 gratuitously naming specimens.
