But though I relinquish the Editorship, I do not abandon 

 all interest and concern in the work. I shall still continue 

 connected with it, and, I trust, shall be a frequent and 

 active contributor, though my absence from the place of 

 publication renders the labours of the active Editorship 

 irksome and painful. 



In consequence of this change, it has been determined 

 to denominate the seventeenth volume of the Aimah of 

 Philosophy the First of a New Series.

I undertake the Editorship of the Annals of Philosophy, 

 announced in the above advertisemetit, with some anxiety j lest 

 the reputation which the work has acquired should be dimi- 

 nished by being placed under my controul. The friendly 

 assurances of Dr, Thomson, that he will continue to contribute 

 to the Annals, will, I trust, convince the reader that the work 

 will in future possess a great share of its present value. 



The successful management of a scientijic journal is ren- 

 dered doubly difficult by the numerous similar sources through 

 which information is now conveyed : relying, however, upon 

 the favourable circumstances i?i which I am placed for the 

 early acquisition of philosophical intelligence, I trust I shall 

 be enabled, with the assistance of which I have received nume- 

 rous promises, to render the work not unworthy of the patro- 

 nage and support of the scientific public.
