"berries, I mean that which is the deepeft in colour; a little
minium brightens it very much. How the minium is to be rec-
tified you may fee among the reds, and polifh the gold before
you ufe the minium on it.

After gold I fhall treat of Yellows, as they fall gradually in
their courle of ftrength.

The firft Yellow is a kind of ftraw colour, and is made of
flower of brimftone, which of itfelf is fine enough to mix with
gum water.

A common way of illuminating prints is by giving the tinc-
ture of gamboge for a Yellow, and this may be of two or three
forts, either fainter or ftronger ; the laft to be a (hade to the
firft, and the laft to be fhaded with the preparation of French
berries.

Yellow oker will make another good pale Yellow ; but it is a
colour, rather of too much body for illuminating of prints; but
yet, being well ground with gum water, it is of ufe after it has
been well wafhed.

The plant celandine will afford another good Yellow, by infu-
fing it in water, and preffing it gently, and then boiling the li-
quor with a little alum ; this Yellow will incline a little to green.

But a Yellow, which fome prefer to the reft, and may be ufed
in feveral capacities of lights^ is one made of French berries, pre-
pared as follows:

Boil two ounces of French berries in a quart of lixivium made
of pearl-afhes and water, till the liquor will give a fine tinge of
Yellow to a bit of paper dipped into it; then pour it off from the
berries, let the liquor cool, and then put it into a bottle for ufe.

Then again put a pint of the fame lixivium to the berries, and
boil them till the liquor is as deep coloured as gall ftone ; and
this will be fit for the fhade of any fort of Yellows you can ufe.

This may be boiled till it produces a brown colour; and will,
with a little ox gall, ferve to fhade any leaf gold that has been
Jaid on paper, and is much preferable to gall ftone in imitating
any gold colour. It anfwers well upon a tincture of gamboge,
or any of the former Yellows.

Next to this may be reckoned the tincture of fafFron, in com-
mon water only, which affords a bright reddifh Yellow, fuch as
one would have, to cover the fhadowed parts of a print, for an
orange colour ; and, when laffron is infuled in rectified fpirits of
wine, there is nothing higher ; but then, except the colour be
loaded with gum arabic, it will fly.

As for a deep Yellow with a body, Dutch pink comes the
.neareft of any to the beforementioned ftrong Yellow made of
French berries in point of colour; and of a lighter Yellow is the
