HARDWICKE'S SCIENCE-GOSSIP. 



23 



NOTICES TO CORRESPONDENTS. 



To Correspondents and Exchangers. — As we now 

 publish Science-Gossip earlier than formerly, we cannot un- 

 dertake to insert in the following number any communications 

 which reach us later than the 8th of the previous month. 



To Anonymous Querists. — We must adhere to our rule of 

 not noticing queries which do not bear the writers' names. 



To Dealers and Others. — We are always glad to treat 

 dealers in natural history objects on the same fair and general 

 ground as amateurs, in so far as the " exchanges " offered are fair 

 exchanges. But it is evident that, when their offers are simply 

 Disguised Advertisements, for the purpose of evading the cost 

 of advertising, an advantage is taken of out gratuitous insertion 

 of " exchanges " which cannot be tolerated. 



We request that all exchanges may be signed with name (or 

 initials) and full address at the end. 



Special Note.— There is a tendency on the part of some 

 exchangers to send more than one per month. We only allow 

 this in the case of writers of papers. 



F. C. Long. — For, information as to stocking and keeping a 

 marine aquarium (and also fresh water kinds) consult Taylor's 

 "•Aquarium," published by Messrs. W. H. Allen & Co., 

 Waterloo Place. 



Wm. Mervyn (Isle of Man). — We shall be pleased to insert 

 your offer of fossil corals, &c. Get Taylor's " Common British 

 Fossils " (published by Chatto & Windus) which will help you 

 to a knowledge of them. 



H. W. Lett.— The Botanical Record Club is still in exis- 

 tence, and doing good work. Address, Mr. Charles Bailey, 

 F.L.S., Ashfield, College Road, Whalley Grange, Manchester. 



Edinoukgiensis.— We quite agree with you _ as to the 

 numerous errors which appear in Adam's " Beautiful Shells," 

 but it is hardly worth while doing other than just calling 

 attention to the fact. 



Professor Phillips.— The papers on " British Hepaticae 

 were published as supplements of Science-Gossip, abundantly 

 illustrated, in 1865, price 4^. Its issue has long been out of 

 print, but Mr. W. Collins, 157 Portland Street, might procure 

 you a copy. 



T. W. D. M.— The address of Mr. E. D. Marquand is 

 Fermain House, Guernsey. 



F. Wilson. — Your discovery as to the sensitiveness of gas- 

 jets at high pressure to musical notes is not new. _ Professor 

 Tyndall and others nearly twenty years ago described what 

 they called "musical flames," and we have seen a gas organ 

 based on this principle in which the tubes were composed 

 of glass, and different lengths of flame and different musical 

 notes were so arranged that simple melodies could be played 

 with them.

 the " Journal of Microscopy," the organ of the Po=tal 

 Microscopical Club, is 1 Cambridge Place, Bath.
