Smith, John: A catalogue raisonné of the works of the most eminent Dutch, Flemish, and French painters: in which is included a short biographical notice of the artists, with a copious description of their principal pictures : a statement of the prices at which such pictures have been sold at public sales on the continent and in England; a reference the the galleries and private collections in which a large portion are at present; and the names of the artists by whom they have been engraved; to which is added, a brief notice of the scholars & imitators of the great masters of the above schools (Part 2) (London: Smith and Son, 1830)

The Writer of the Catalogue Raisonne,
begs respectsully to offer his assistance professionally for the
Purchase and Sale of Pictures, estimating their value, ascer-
taining the Masters by whom they are painted, making Cata-
logues of Collections, and giving an opinion relative to their
state and preservation.
The practice and experience of nearly twenty five years, in
the commerce of Works of Art, aided by arduous study and
zealous attachment to the pursuit, are the qualisications which
the Writer ventures to adduce as some recommendation to the
confidence of Gentlemen who may have occasion to employ him
for either of the above-named objects.
It must be obvious to Gentlemen, that no species of property
is of a more uncertain value than Pictures, arising srom a
variety of causes; one of which is the disficulty which the
inexperienced eye feels in ascertaining correctly their origi-
nality and their consequent value; another, is the accidental
event of a paucity of buyers. These, and other dissiculties of
the kind, may srequently be obviated by consulting a person
conversant in such matters, by whose advice much valuable
property may osten be preserved srom loss, either by premature
and injudicious sale, or the injurious effects of time. For a
copious notice of these subjects, the Reader is reserred to the
Introduction of the First Part of this Work.
