much heighten its blacknefs, and even make it appear

Lacmus or Litmus Blue. This is a beautiful Blue, and will
run in a pen as free as ink. It is made of lacmus, or as fome
call it litmus, which may be had at the druggiffcs.—But, as this
colour is never to be met with prepared, I (hall here fet down
the method of preparing it:
Take an ounce of lacmus, and boil it in about a pint of
fmall beer wort, till the colour is as flrong as you would have
it; then pour off the liquor into a gallipot, and let it cool for
ufe ; it will foon become a jelly, and by degrees grow hard.
But this colour is to be opened again, and made liquid by
xvater, fo as to be ufed as ink ; and will be either paler or darker,
as it is made thicker or thinner. This affords a bright colour,
and has extraordinary effects; for it is not only a beautiful, but
a holding colour.
It is a good made for ultramarine, or Blue bice, where the
ilrongeft Thades fhould not be extremely deep ; and for colour-
ing of prints it is very good, as it is a tranfparent colour, and
goes a great way.
A tranfparent Blsje from Mi". Bvyk equal to ultramarine.
This is a beautiful Blue, and the chief ingredient of which it
is made, is the cyanus or Blue cornbottle-flower, which abounds
a.lmoft in every corn-field, and may eafily be had, during four
of the fummer months; and may fee gathered by children about
the fkirts or verges of corn-fields, without doing any damage
to the corn. This flower has two Blues-in it, one of a pale
colour in the larger outward leaves, and the other of a deeper
Blue that lies in the middle of the flower.
Both thefe will dc, being feparated from the buttons or cafes,
in which they grow ; but the deep Blue leaves in the middle
produce by much the beft colour; which may' be obferved by
rubbing the leaves, while they are frefh, fo hard upon a piece
of good writing-paper, as to prefs out the juice, and it will yield
an excellent colour, which will not fade, as has been found by
the experience of two or three years. This part of the flower
is therefore the principal, and what may be depended upon ;
which fhould be picked from the reft of the flower-leaves, the
fame day, if ip Riay fee, or the next, or as foon as poffibly
£an be.
A good quantity of thefe middle leaves feeing procured, prefs
,out what juice you can from them, and add to it a little alum,
and you will have a lafting, tranfparent Blue, of as bright a
ftaining colour as can be defired, fcarce inferior in beauty to
ultramarine, and as durable. As for the outward flower-leaves
which are paler, it is not certain that they will anfwer tha
