The object of these two Catalogues is, to convey a more satisfactory notion of the contents of the books in them, than can be drawn from reading the titles.  Instead of laudatory extracts from reviews, general notices are given of the chief subjects and most prominent peculiarities of the books.  The Catalogues are designed to put the reader, as far as possible, in the same position as if he had inspected for himself, at least cursorily, the works described; and, with this view, care has been taken, in drawing up the notices, merely to state facts, with but little comment, and no exaggeration whatever.
