HARDWICKE'S SCIENCE-GOSSIP. 



[March 1, 1870. 



NOTICES TO CORRESPONDENTS. 



All communications relative to advertisements, post-office 

 orders, and orders for the supply of this Journal, should be 

 addressed to the Publisher. All contributions, books, 

 and pamphlets for the Editor should be sent to 192, 

 Piccadilly, London, W. To avoid disappointment, contri- 

 butions should not be received later than the 15th of each 

 month. No notice whatever can be taken of communica- 

 tions which do not contain the name and address of the 

 writer, not necessarily for publication, if desired to be with- 

 held. We do not undertake to answer any queries not 

 specially connected with Natural History, in accordance 

 with our acceptance of that term ; nor can we answer 

 queries which might be solved by the correspondent by an 

 appeal to any elementary book on the subject. 



C. F. T. — It is certainly not a good season of the year to go 

 out collecting Desmids or Diatoms. Spring or autumn would 

 be better. 



P. F. — Mining larvae. Only by picking off the leaves and 

 barning them. 



T. S.— Read the notice at the head of " Exchanges." 



P. G. — We cannot tell without examination. 



S. T. R.— We could not give space to answer all your 

 queries. For stuffing birds, procure Gardner's "Taxidermy "; 

 tor mounting butterflies, &c, Knaggs's " Lepidopterist's 

 Guide." 



J. S. — The "vivarium " is made from designs, and the 

 cost and style depend on the taste of the person ordering 

 them. None are made up for sale, that we are aware of. 



J. S. R. — The sweet-scented Butterbur is not so rare that 

 we should record its stations. It is an " escaped " plant. 



F. G., Seaforth. — The barren rooting portion of some 

 species of Polyporus, formerly regarded as a "complete" 

 Jungus, under the name of Rhizomorpha subcorticalis. 



G. S. T.— J. A. H. — We shall decline in future to insert 

 "Exchanges" unless the names are written in full, and 

 legibly. It is a slovenly habit which some naturalists affect. 



J. B. R.— Lowne's "Anatomy of the Blow-fly " is published 

 by Van Voorst (London). 



G. B. C— The Common Hare, Irish Hare, and Alpine Hare 

 are all regarded by some naturalists as distinct species. 



C. S. G.— You can either transfer them or replace the 

 spirits without injury to the specimens. 



F. E. — Hooker & Bentham's " Genera Plantarum " is pub- 

 lished by Reeve & Co. Vol. I. is issued, and more to follow. 

 The descriptions are in Latin. 



G. F. C— Your A and B is a Stentor, but what the others 

 are we will not attempt to determine from a sketch. 



R. R. — The lichens were, No. 1 . Purmelia perlatu, L. ; and 



No. 2. Purmelia suxatile, L. — W. C. C. 

 F. O. M.— It is the caterpillar of Zeuzera JEsculi. — F. M. "Z 

 Buroeoning. — All correspondents who forwarded replies 



not inserted will please to accept the Editor's thanks. 



EXCHANGES. 



Notice. — Only one "Exchange" can be inserted at a 

 time by the same individual. The maximum length (except 

 for correspondents not residing in Great Britain) is three 

 lines. Only objects of Natural History permitted. Notices
