HA R D WICKE ' S SCIENCE-GOSSIP. 



To our Recent Exchangees. — We are willing to be helpful 

 to our genuine naturalists, but we cannot further allow dis- 

 guised Exchanges like those which frequently come to us 

 to appear unless as advertisements. 



J. B. W.— You cannot do better than procure Dr. Cook's 

 book, price 5s., one of the volumes of the "International 

 Scientific Series," entitled "'An Introduction to Freshwater 

 Algae," with an enumeration of all the British species. It is 

 illustrated by thirteen plates, with all the details of the species, 

 beautifully drawn, amounting to one hundred and twenty in 

 number. 



T. B. G.— No ; the mineral is evidently a piece of green 

 Fluor-spar, commonest found in this country in the lead-mines 

 about Alston Moor. 



T. W. S. — " Notes on Collecting and Preserving Natural 

 History Objects," edited by the present editor of Science- 

 Gossip, was first published by Messrs. Hardwicke and Bogue 

 in 1876. It was contributed to by twelve of the most dis- 

 tinguished practical naturalists of the time, in the several 

 departments of scientific work that were known, in addition to 

 the introductory essay by the editor on " Geological Speci- 

 mens." The latest edition, we believe, was published by 

 Messrs. W. H. Allen & Co., Waterloo Place, Pall Mall, to 

 whom please apply for copies, price $s. 6d. 



F. G. A. — The specimens you sent us were very much 

 decomposed. They were evidently those of the fungus Peziza 

 aurantium, or orange-coloured Peziza. It is one of the largest 

 species of the genus, and if properly taken up with the turf in 

 which you found it, will keep for a fortnight underneath a 

 glass-shade. 



F. P. — Consult the prefatory essay on " The Geology of 

 Suffolk," as to the best existing collecting-grounds for crag 

 fossils. Nearly all the old pits and sections are now closed, 

 since coprolite working ceased to pay.
