QUE LETTEE-BOX. 



Erkatitm:. — In March No., " Things of the Season," for " Red- 

 wing, Thrush ;" read " Kedwing-Thrush"' (Turdus Iliacus) . 



Taxidermy. — A.S. Hinckley. — Mr. Hall says, " I divide the leg 

 from the body of the bird, at the top of the femur, learing the 

 whole of the thigh bone intact ; many birds show the whole of that 

 bono when alive, hawks in particular. 



Infusokia. — R. R. — Mr. Pritchard is preparing a Fourth Edition 

 of his work, to which i)r. Arlidge, Mr. Ralfs, and Professor 

 Williamson all contribute. Mr. Tuften West will illustrate the 

 DiatomaceoB. The price to subscribers will be Thirty Shillings. 



M. D. — The substance looks like compressed stercus, and not 

 like a fungus at all. We cannot make it out. 



Received. — "Notice of the occurrence of mammoth and other 



animal remains discovered under limestone in a bone cave at Shan- 

 don, Co. Waterford." By E. Brenan, Esq — W. H. B.— Heferred 

 for immediate consideration. — M. AV. Wells. — D. B., Glasgow, 

 referred. — R. G. — It is a great convenience to the reader, and when 

 properly done unobjectionable.— G. I''. W., Bedford Square.— They 

 really are too trivial to occupy the place you suggest, but could be 

 cut out and mounted on a fly leaf.— J. B. Q., Durham. — Accepted. 



ELECTBO-METALLuaT. — Zbba. — A gold coiu may be treated the 

 same as a silver one, and either may be gilt and burnished ; the 

 length of time the solution lasts depends on the intensity of the 

 action, and tho amoimt of surface on which the deposit falls. 



Portable Fubnace.— J. P. K. — We are not awaie if it has been 

 manufactured for sale.
