HARDTTICKE'S SCIENCE-GOSSIP. 



[March 1, 18GS. 



NOTICES TO CORRESPONDENTS. 



W. B. Towey.— Are you really ignorant of what Diatoms 

 are ? then consult our first volume, p. 27, " Diatoms : what 

 they are." 



W. S., Rosemary Lane, Whitehaven.— -Why did you not 

 furnish an address to your exchange notice sufficiently ex- 

 plicit for letters to reach you ? We can send you half a dozen 

 returned envelopes. 



G. T. N. — We must insist upon using at least the initials of 

 our correspondents to their communications, or how can we 

 possibly identify them hereafter ? 



F. M. B. — It is Pupa muscorum (young). 



C. P. C— See Science-Gossip for 1866, p. 228, fig. 21". If 

 our correspondents read their Gossip more carefully, they 

 would not continue to send us " oak spangles " to be named. 



R. J. C. will find the information he requires in "The 

 Microscope," by Dr. Carpenter, price 12s. 6d. (Churchill), or 

 perhaps sufficient in " Hogg's History' of the Microscope," 

 price "s. 6d. (Routledge). 



E. T. S. confounds together in a most extraordinary 

 manner several species of Acuri, and calls them all cheese 

 mites. We have had enough of negroes and the " unity of 

 mankind." 



G. A. W.— For mounting, obtain " Davies on Preserving 

 and Mounting Objects," price, 2s. 6d. (Hardwicke). For 

 naming or identifying, no general work surpasses " The 

 Micrographical Dictionary," 45s. (Van Voorst). 



J. E. M.— No one would undertake the naming of your 

 insects, unless you have duplicates to offer for the labour. 



E. T. — Put them in an ants' nest, and the work will be done 

 for you. 



W. E.— Probably Tabanus lovinus.

 (Brachythecium) rutabulum. 4. Frullania dilatata. — R. B. 



T. I. W. — "Carpenter's Zoology," 2 vols, nine or ten 

 shillings. Address the other question to the Lancet or 

 Medical Times.

 Modem, in Medical and General Science," by R. G. Mayne, 

 M.D. Thick 8vo., 45s. (Churchill). " Dictionary of Natural 

 History Terms, with their Derivations," by David H. M'Nicoll, 

 M.D. Small 8vo., 12s. (Reeve & Co.) Both give the 

 derivations. 



R. S. — You can obtain specimen of Euplectella of Mr. W. 

 Cutter, 35, Great Russell Street, Bloomsbury. 



W. F. H. — Several notes on drying plants are scattered 

 through our volumes. Collected information on forming a 

 herbarium will be found in a chapter of "A Fern Book for 

 Everybody " (Warne and Co.) 



Sii.ex will find what he requires in " Beach Rambles in

 H. C. Sorby in Popular Science Review, January, 1866. 



J. C. — The seaweed is Gymnogongrus plicatns.— J. E. G. 



W. R. H. — A modification of an ordinary small microscope 

 would answer your purpose, with a large tube and large eye- 

 piece. This would only cost a few shillings additional.

 mous correspondents. 



J. R. B. — For moths and butterflies, " Stainton's Manual,"

 the snow is on the ground.

W. E. P. — Yours is not a Bat hair, but probably that of 

 some Rodent. We have no unmounted Bat's hair.

B. T. — The creatures found in Balanus are the larva? of
