To Make Moulds Of Horn
If you wish to take the impression of any coin, medal, &c., previously
anoint it with oil; then lay the horn shavings over it in its softened
state. When dry, the impression will be sunk into the horn; and this
will serve as a mould to re-produce, either by plaster-of-paris, putty
and glue, or isinglass and ground egg-shells, the exact resemblance of
the coin or medal.
