alfo two C's, the one within the other.

CELERITY, is reprefented, in painting, by a woman, with
a thunderbolt in her right hand, a dolphin by her fide, and a
hawk riving in the air.
The moral is obvious; all thofe things being naturally very
quick in their motion, which well exprelTeth Celerity.
CEMENTS, as to melt cryjialfor a Jirong Cement. Pound
cryftal, and put it into an iron ladle; cover it and lute it well,
and heat it on the fire till it is red-hot, which quench in oil of
tartar; this do fo often, till they will be eafily reduced to pow-
der in a mortar, which will then eafily melt.
This is of ufe to make a ftrong cement, and to counterfeit
jewels with.
To make a Cement for broken glaffes.
1. Mix glair of eggs with quick-lime ; and this cement will
join broken pieces of glafs together, and all earthen pots, fo that
they will never break in the fame place again.
2. Or thus, Take old liquid varnifh, and join the pieces with
it j tie them together, and dry them well in the fun, or in an
oven, and they will never unglue again; but you muff, not put
hot liquor into them.
3. Take white lead, red lead, quick-lime, and gum fanda-
rac, of each half an ounce, and mix all thefe with the glair of
four eggs.
4. Take quick-lime powdered, liquid varnifh, and glair of
eggs, of each a like quantity ; grind them upon a ftone; this
will be a ftrong cement even for ftones. Or,
5. Take white lead, bole, and liquid varnifh as much as
fufficeth. Or,
6. Take fine powder of glafs, quick-lime, and liquid varnifh,
of each a fufEcient quantity.
7. Take calcined flints and egg-fhells, of each a like quan-
tity, and, with whites of eggs and gum tragacanth, or diffolution
of gum fandarac, make a cement. This in a few days will be
as hard as a ftone.
8. Take of calcined flints two pounds,quick-lime fourpound?,
as much linfeed oil as may temper the mixture ; this is a very
ftrong cement, but with liquid varnifh would be ftronger.
9. Take fifh glue, and beat it thin ; then foak it in water till
it is like a pafte; make rolls of it, which draw out thin, and,
when you ufe it, difTolve it in fair water over the fire, letting it
feethe a-while, keeping fcumming of it, and ufe it while it is hot.
CERUSS, a preparation of lead, commonly called white lead,
and, by the chymifts, calx of lead.
