_Prospectuses_ (Vol. viii., p. 562.).--I have seen a very curious volume of
prospectuses of works contemplated and proposed, but which have never
appeared, and wherein may be found much interesting matter on all
departments of literature. A collection of this description would not only
be useful, but should be preserved. A list of contemplated publications
during the last half century, collected from such sources, would not be
misplaced in "N. & Q.," if an occasional column could be devoted to the
subject.
