TO CORRESPONDENTS. 



Recommendations similar to those constituting the Paper <' On a more 

 ccconomical Application of Solar Heat," have already frequently been 

 made public— We shall have much pleasure in receiving the Communi- 

 cations offered by Mr. Kenwood.— The Review of Mr.RENNiE's Edition 

 of Montagu's Ornithological Dictionary is unavoidably postponed till 

 our next Number ; in which we shall also notice Mr. Young's very 

 elegant and perspicuous Treatise on the Diffierential Calculus. 



%* The Editors request that all Communications intended for immediate 

 insertion may be sent to the care of Mr. Richard Taylor, Printing Office, 

 Red Lion Court, Fleet Street, London, at furthest by the I5th day of the 

 month, or they will be too late to appear in the ensuing Number.

 kingdom, of a general wish that the friends of science should assemble at 

 York during the ensuing autumn, we are directed to announce that the
