HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



To Subscribers. — The compilation of the Classified Index 

 of the last twelve volumes of Scienxe-Gossip has proved a 

 more difficult and painstaking task than we at first imagined. 

 It is now in a forward state of preparation, and we crave a 

 little grace from our numerous correspondents, who have 

 already applied for it. 



To Correspondents and Exxhangers. — • As we now 

 publish Science-Gossip at least a week earlier than hereto- 

 fore, we cannot possibly insert in the following number any 

 communications which reach us later than the 8th of the 

 previous month. 



M. M. — The " E.xchanges " in our last page are mainly con- 

 fined to Natural History subjects. 



W. E. T. — We refer you to "The Aquarium: its Inhabi- 

 tants, Structure, and Management," just published at 6s., by 

 Hardwicke & Bogue, 192, Piccadilly, for fuller answers to all 

 your aquarium questions than we have space to give. The 

 book is copiously illustrated, and you need not have any 

 difficulty in successfully carrying out your object. 



R. W. — Many thanks for your suggestions. 



I. Crawford. — Swainson's "Taxidermy" was published by 

 Longmans, at, we believe, 6s. Grattann's "Seaweeds" was 

 published at the Bazaar Office, London, at 2s. or 2s. 6d. 



J. W. G. — The specimen sent is Gorgonia flabelhim. 



T. Lisle. — Get Wood's "Insects at Home" (Longmans), 

 the new and, we believe, cheaper edition. 



E. H. — Our correction is the right one. 



Dr. D. — We should advise ringing the slide with asphalte. 



R. N. V. — The calculations based on the observations made 

 during the late "Transit of Venus" Expedition have not yet 

 been published. 



W. G. P. — The only work we know is Stainton's "Tineina 

 of Southern Europe," i6s. (Van Voorst) ; Rye's " British 

 Beetles," los. 6d. (Reeves). 



W. Saunders. — Get Greene's "Insect Hunter's Com- 

 panion," and Merrin's " Lepidopterist's Calendar," — both of 

 them cheap books. 



C. V. Green. — We omitted to say that the specimens of 

 fungi were in a state of deliquescence when they reached us, 

 and utterly unidentifiable. 



W. H. Legge. — We believe your egg is a lighter specimen 

 than usual of the Blackcap Warbler — not the Garden Warbler. 



J. H. P. (North Shields).— We should imagine the "Micro- 

 graphic Dictionary," published in half-crown parts by Van 

 Voorst, would be the kind of book you require. 



W. J . Vandenbergh. —We are afraid your fossil from the 

 Suffolk Coprolite pits has been over-estimated in value. Frag- 

 ments of deers' antlers are often met with. You had best send 

 it to us for further remark. 



H. J. McG. — Your specimen is the Winter Aconite 

 (Eranthis hyeiualis), not a truly indigenous plant. 



A. W. RosLiNG. — You had better send us a specimen. They 

 appear to be eggs of some kind, but we cannot undertake to 

 name them from your drawing. 



To Various Querists. — We are not aware by whom, or at 

 what price, the volume of the North Staffordshire Field 

 Naturalists' Club (noticed in our last number) is published. 

 You had better inquire of the President, Mr. John Ward, 

 F.G.S., Longton, Stoke-on-Trent.
