HARDWICKE'S SCIENCE-GOSSIP. 



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 our 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. 



To our Recent Exchangers. — 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. Wright.— Your plant is the common goat's beard 

 {Tragopogon pratensis), one of our commonest wild flowers. 



F. G. Bing.— The sea-weed sent is covered not with "minute 

 egg-cases," but with the empty cells of a common Bryozoan 

 {Membranip&ra membranaced). See Taylor's " Half-hours at 

 the Sea-side," for illustration. 



R. W. G. — You had best inquire of W. Harcourt Bath, Esq., 

 The Woodlands, Ladywood Road, Edgbaston, Birmingham, 

 respecting his various works on Dragon-flies, because in 

 England he is our chief authority on this lately sought out 

 department of Entomology. 



M. A. Idle.— Any bookseller will supply you #ith a half- 

 crown volume on the subject you require, and will give you the 

 necessary instruction. 



Equus. — You can get from the publishers of Sowerby's 

 Botany (Messrs. George Bell & Sons, York Street, Covent 

 Garden} any volume you like. Write to them. 



D. E. F. (Barbados). —The Scientific Circulars and 

 Catalogues issued by Messrs. Dulau, 37 Soho Square, London, 

 and Messrs Wesley & Sons, Essex Street, Strand, will afford 

 you all the information you require. 



J. R. (Hong-Kong). — Address Mr. William P. Simmons, 

 Hon. Sec. Microscopical Soriety, 6 Hastings Street, Calcutta. 



J. B. King. — You could hardly do better than present a copy 

 of dear old Kingsley's " Glaucus " to. your son ; but get a first 

 edition, if possible. 



K. G. — Most sea-side railway libraries are now supplied with 

 good and cheap books, relating to the popular Zoology, Botany, 

 Geology, etc., of the locality. 



E. Pratt and others. — The question of publishing a com- 

 plete up-to-date General Index of "Science-Gossip" has been 

 repeatedly raised. With the publishers it is, and must be, a 

 commercial question; but the Editor and his friends of the 

 last twenty-one years know there is no such Natural History 

 Cyclopedia in the world as the volumes of Science-Gossip 

 from the commencement.
