HARD WICKE'S SCIENCE- G OS SIP. 



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. 



W. A. Clarke. — The occurrence of the two distinct colours 

 and varieties of chrysanthemum on the same .stalk is very 

 curious and uncommon. 



B. Prosser. — We suspect that the reference to the "scales " 

 on the wings of insects other than butterflies and moths is 

 erroneous. It may refer to the scales on the bodies of such 

 insects as the Thysanuridas. 



P. H. R. — See article in Science-Gossip, vol. xii. p. 263, on 

 " How to Manage a Formicary." 



W. J. Horn. — From your sketch, we judge the creature to 

 be a species of Pianola. 



D. W. — The "nuts" are the seed of the Chilian pine [Arau- 

 caria imbricata). 



M. T. Denne. — Your specimens are : No. 1, Plumu'aria 

 pinnata ; 2, Flustra cJiartacea ; 3, Dij>hasici rosacea; and 

 4, Sertularia filiculata. 



J. B. — In purchasing a microscope for thefir-t time, we think 

 it would be better to get one with rack and pinion, and get used 

 to working it. The objectives could be purchased as you 

 needed them. 



W. Duncan. — The specimen appearsto.be a variety of Alcyo- 

 nidium parasiticum. No. 1 is not a Lepraha, but perhaps a 

 species of Cellaria or Hippothoa — too indistinct to identify. 

 No. 2 is a species of Microporella encrusting Flustra foliacea. 

 No. 3, Lepralia coccinea.
