_Biographical Dictionary_ (Vol. iv., p. 483.).--It is almost unnecessary
to direct Z. Z. Z. to the _Biographical Dictionary_ of the Society for
the Diffusion of Useful Knowledge, inasmuch as it is but a splendid
fragment, comprising only the letter A, in seven half-volumes. But it
may be of use to call attention to this work; and as, from an
examination of the plan, the names of the contributors, and that of the
editor, no one can have any doubt of its worth and superiority, so one
would imagine that an enterprising publisher might take up the
continuation of it without risk.
