TO READERS AND CORRESPONDENTS, 



■Reviews of the Philosophical Transactions, of Dr. Tui'ner's Elements 

 of Chemistry, of Mr. Faraday's Essay on Chemical Manipulation, and of 

 several other scientific works, have been postponed for want of room. 

 We shall certainly notice them in our ensuing Number. 



The letter of F. R. S., and the paper signed ** Inquisitory' are in re- 

 serve, as we conclude some material change must soon take place. 



An account of the several Courses of Lectures delivered during the 

 season in the Royal Institution, and of the proceedings of the general 

 and other meetings of the members, was intended for this Number, but 

 the pressure of oth6r matter, and the length of our report of the weekly 

 evening meetings, has obliged us to delay its insertion. 



We are requested by Mr. Faraday to publish the following errors which 

 occur in his work, entitled Chemical Manipulation , with their corrections. 

 They are errors of the press, which are not self-evident, and might lead pupils 

 into mistakes.
