APHORISMATA ENTOMOLOGICA. 21
width as the rest of it. Till this glass jar Avith plaster of Paris up
to a sufficient height, namely, so far as to leave sufficient depth for
any insects you may Avant to relax between the surface and the cork.
Pour on the plaster as much water as it will absorb, any surplus
being poured off, and over it place a round piece of perforated zinc,
the size and shape of the orifice of the jar, the object being to keep
the wings of the insects from touching the wet surface; and at the
same time the holes in the zinc answer admirably for putting the pins
of the insects into, so that they are steadied, and in a manner fixed,
so as not to shake about if the jar is moved.
"When you have thus placed the said insects in this way, put the
cork or stopper tightly into the jar, and in a few hours, more or less
according to the size of the specimen, you will have them excellently
relaxed, and that Avithout the slightest detriment or damage; the doAvn
being as perfect as if they had never been subjected to any such pro­
cess at all. A tin canister will answer the purpose, but not so well;
the jar, especially if it have a glass stopper, being so much more air­
tight, and the moisture being therefore the more confined. If a cork
be used, it should have a piece of fine kid leather round it, to make
it fit close; also, I recommend a basket-work case to guard the lower
part of the jar.
