I PROJECTED the Annals of Philosophy in the year 1812, 

 and have continued to be the Editor ever since, with th6 

 exception of a single year, when my sudden removal to 

 Glasgow, and the necessity I was under of beginning a 

 laborious course of Chemical Lectures with scarcely any 

 previous preparation, and with no assistant, put it out of 

 my power to devote a sufficient portion of my time to the 

 laborious and diversified duties of Editor of a periodical 

 work of science. My friends Dr. Bostock and Mr. Arthur 

 Aikin were kind enough to supply my place during that 

 year; and carried on the Annals of Philosophy with a 

 spirit which left the readers no cause to regret the tempo- 

 rary absence of the original Editor. The principal object 

 which I had constantly in view was to render ihe Amials as 

 complete a register as possible of all the improvementls 

 made in chemistry and the kindred sciences, not merely in 

 Great Britain, but in every part of the world. How far my 

 exertions were attended with success, it is not for me to 

 determine, though I can say with truth that neither labour 

 nor expense was spared to fulfil, as far as was in my power, 

 the objects which I had in view. 



After a trial of two years, I have satisfied myself that a 

 residence more than four hundred miles distant from the 

 place of publication is scarcely consistent with the active 

 duties of an Editor. It more than quadruples the labour, 

 while it diminishes, almost in the same proportion, its suc- 

 cessful exertion. I have, therefore, with the concurrence of 

 the pubhshers, transferred the Editorship of the Annals of 

 Philosophy to my friend Mr. Richard Phillips, a gentleman 

 whose scientific talents and acquirements are too well 

 known to require any observations on my part.
