HARDWICKE'S SCIEN C E - GO S SI P. 



NOTICES TO CORRESPONDENTS. 



J. Sargent, Jun. — The insects are a species of Cnccus, 

 females. The eggs are hatched under the body of the 

 mother, which serves as a cocoon. The " Cochineal insect " 

 is a well-known member of this class. 



Rev. S. a. B. — The pinnule certainly reached us as de- 

 scribed. " White Varieties " became a drug in the market. 

 Hence our closing our columns to their further discussion. 

 As to the rest, accept our apologies. We will inquire into 

 the matter. 



T. R. should refer to the vol. for 1872 ; at page 231 he will 

 find all the information he requires respecting dyed sections 

 of wood. 



A. P. S.— See vol. for 1872, page 118, for an answer to your 

 query respecting Paste Eels. 



C. H. M.— They are the specific name?, of well-known 

 butterflies. See Newman's *' British Butterflies." An ento- 

 mologist would have been in no difficulty about them. 



A. O. W., and " Bryum."— Answers next month. 



E. C. J. — An unavoidable delay has arisen in the naming 

 of the zoophytes. Both these and the fungi will appear in 

 our next. Latter arrived too late for insertion in present 

 issue. 



A. Smyth. — The Bombyx Cynthia is the same species as 

 that you name. The other species is believed to be the 

 Japanese silk-worm, now much cultivated. Your third 

 query is rather vague. Newman's " Butterflies " and 

 "Moths" would do for the Lepidoptera ; Rye's "British 

 Beetles " for Coleoptera; and Stephen's and Hubner's great 

 works are the only other general ones. 



R. H. Philip. — We cannot undertake to name small 

 seeds. 



J. C. H. — Our correspondents should remember that our 

 rule of priority in the insertion of" Exchanges," &c., cannot 

 be departed from. As we every month receive more than we 

 can insert, it follows that some must stand over. These are 

 always the last received. 



J. F.— We cannot open our columns to complaints of 

 Publisher's delays. The best plan would be for J. F. to write 

 to the publishers about this grievance. We thoroughly 

 sympathize with it. 



C. L. Archer.— See paragraph in Microscopical column of 

 Science-Gossip for December on " Mounting in Dammar." 



F. H.— Your communication will receive our attention. 



A. E. Murray.— The small fungi on the piece of wood 

 were Agaricus epiphyllus; the other was a portion of 

 Polyporus. 



G. Grant.— Your specimen was a piece of coke that had 

 got among your coal ! 



J. B.— Many thanks for the slides. The sections are admi- 

 rably cut. 



"Hernshaw" and "Micrographic Dictionary."— We 

 have received so many communications from kind readers on 

 these subjects that we do not think it necessary to devote a 

 number to them ! 



W. N. wishes to know of any Field Club or General 

 Natural History Society in the North-east of London. 

 Perhaps some of our correspondents can answer him. 



E. H. — We do not think you could do better than adver- 

 tise your collection in our columns, stating what they are. 

 Send such an advertisement to the publisher, 192, Piccadilly, 

 for price, &c. 



Edwin Clarke. — Your specimen is the male plant of the 

 common Hemp, 



F. M. C. — A re-issne of the " Micrographic Dictionary " is 

 slowly going on. You can begin to take the monthly 

 numbers whenever you think fit, price 2s. 6d. each. The 

 publisher is Van Voorst.
