To Readers and Correspondents. 



An account of" the Overflowing- Well at the Horticultural Society's 

 garden, at Cliiswick, with a description of the method employed in boring 

 for water, will appear in our ensuing number. 



The Meteoric Stone supposed to have fallen at Coddenhain, which is 

 noticed in our last number, (p. 1S4,) is, it seems, merely a nodule of flint. 

 Its history has been particularly inquired into, by the Rev. W. Kirby, of 

 Barhain, and it appears to have been picked up, during a thunder storm, 

 at a place struck by lightning. Mr. Braylcy of Islington, to whom we 

 are indebted for thi3 information, remarks, that "having examined all the 

 relations of the falls of meteorites which I have been able to procure, in 

 consequence of being engaged in a work on the subject, I have not met 

 with a single authenticated instance of the fall of a meteorite, during a 

 true thunder storm." We regret that Mr. Brayley's communication 

 reached us too late for insertion. 



We had prepared an account of the Progress of Foreign Science for 

 the present number, but have no room for it. Our ensuing number will 

 contain a long article on this subject. 



We have not received the work of MM. Monticelli and Covclii, which 

 pur Correspondent at Milan wishes us to nuiice.
