_A Lexicon of Types._--Can any of your readers inform me of the
existence of a collection of emblems or types? I do not mean allegorical
pictures, but isolated symbols, alphabetically arranged or otherwise.
Types are constantly to be met with upon monuments, coins, and ancient
title-pages, but so mixed with other matters as to render the finding a
desired symbol, unless very familiar, a work of great difficulty. Could
there be a systematic arrangement of all those known, with their
definitions, it would be a very valuable work of reference,--a work in
which one might pounce upon all the sacred symbols, classic types,
signs, heraldic zoology, conventional botany, monograms, and the like
abstract art.
