Supplement to the Encyclopedia Britannica, 6 vols. 4to. from John 
Dunlap, Esq. of Edinburgh, for Yale College Library, 1824. 
With a few exceptions, we have omitted to mention Journals, 
whether foreign or domestic, received in exchange ; and among nu- 
merous foreign Journals of Science and Literature, which arrive 
more or less regularly, we have named only those which have re- 
cently begun to come, or which have been revived, after a discon- 
tinuance. 
For want of time and space, we must omit any remarks which we 
might, otherwise, be disposed to make on some of the publications 
named above, and for the present can only make our acknowledg- 
ments (in some cases too long delayed) to authors, editors, publish- 
ers, and others, who have been so kind as to forward them to us.—Ed.
