HARDWICKE'S SCIENCE-GOSSIP. 



[Dec. 1, 1SG0. 



NOTICES TO CORRESPONDENTS. 



T. R.— The supposed fossil is a nodule of iron pyrites. 



J. H. G.-We could not expend time in the examination of 

 an object in which you can find "no structure." Single 

 slides are best sent by post in the small black cases sold by 

 opticians. 



B. t.— The slides would be acceptable, and may be sent to 

 the Secretary, 5, Hanover-square, W. We have heard nothing 

 of the supplement you allude to. 



H. H. K. — The small crabs are Pinnotheres pisum. — 

 J. E. G. 



E. F. B. — The parasite of the prawn is Bopyrns crungonus 

 Latr.— J. E. G. 



J. G. — No. 1, Salsola kali; 2, Salicomia herbacea ; 3, C/ie- 

 nopodium murale; 4, Parietaria diffusa; 5, Corrigiola litto- 

 ralis ; 6, Lepigonum marinum. 



J. H. C. informs us that he has had 170 applications for 

 Adriatic sand, as announced in Science Gossip. 



H. W. — Cases for yearly volumes of Science Gossip may 

 be had of the publisher at Is. 6d. No other cases are 

 published. 



A. B. — Much more handsome cells are turned out of 

 wood. 



J. P. — No better than English oak. We cannot insert trivial 

 exchanges which will bring credit to no one. 



J. W. — No improvement on the ordinary section machine, 

 and could not be made by an amateur. 



W. E. M. — Had you read carefully, you would have ob- 

 served that E. T. Scott stated he made the glass himself. 



J. A., Jun. — If you signed your name in full, you would 

 have no occasion to complain of us. The remedy is in your 

 own hands. 



A. L. — The colours of caterpillars vary much after their 

 castings. 



C. A. J. — We cannot name a plant from mere leaves, with- 

 out cither flower or fruit. 



W. H. B.— The Sowbread (Cyclnmen) flowers in autumn. 

 Wood, Robert. — The eggs of the insect. 

 C. C. W. — We know of no microscopical club in London 

 which professes to admit lady members. 

 II. Y. J. — We can see no parasite. 



J. E. — It is probably the Long-eared Bat (Plecotus auritus), 

 but your figure does not give the character of either nose or 

 eyes. 



H. E. W. — Dried plants are not usually mounted in books, 

 except Ferns, for which albums are sold at 192, Piccadilly. 



W. L. H. — The attempt to preserve fungi in solution has 

 been tried, without much success. You must describe what 

 kind of bottles you allude to before we can answer. 



H. P. A. — The spider is Salticas scenicus, as far as we can 

 judge from its dried condition. 



W. T. H. — A species of Ichneumon parasitic on the Buff- 

 tip Moth.

 by Routledge & Co., London. 



C. P. S. — We have not seen the pollen of Monsteru deli- 

 ciosa. 

 E. G. V. — On cabbage-leaves. — Macrosporium Brassiere. 

 P. A. J. — A piece of recent coral, too fragmentary for iden- 

 tification, possibly Meundrina. — R. T. 



C. D. — The cocoon of one of the Cimbecidce, of the order 

 Hymenoptera. — F. 71/. 

 C. B. — The eggs of a spider. 



E. B. — Caterpillars of a Lepidopterous insect, but, being 

 dend and shrivelled, could not be identified. — F. 31, 



R. S. — The best book we know of for your purpose is 

 " Noad's Student's Text-book of Electricity," just published 

 by Lockwood & Co. 



C. P. S. — Why attempt to improve upon Nature ? Let the 

 poor creature have its wintry sleep. 



J. G. B. — Ecclesiastes ii. 14. Science Gossir, vol. ii., 

 p. 228, figs. 217—219.

 will be well. No objection to the corks you name. 



11. T. — The common European tortoise {Emys lutraria). 

 Mr. King, Portland-road, London. 



E. W. — When we depend upon others, we cannot always be
