ty_ to some more especially, or to all alike: or thirdly, by
uniting and interweaving it self with some other body that is already
joyn'd with the tinging particles, with which substance it may have a
_congruity_, though it have very little with the particles themselves: or
fourthly, it may alter the colour of a ting'd liquor by dis-joyning certain
particles which were before united with the tinging particles, which though
they were somewhat _congruous_ to these particles, have yet a greater
_congruity_ with the newly _infus'd Saline menstruum_. It may likewise
alter the colour by further dissolving the tinging substance into smaller
and smaller _particles_, and so _diluting_ the colour; or by uniting
several _particles_ together as in precipitations, and so deepning it, and
some such other ways, which many experiments and comparisons of differing
trials together, might easily inform one of.

From these Principles applied, may be made out all the varieties of colours
observable, either in liquors, or any other ting'd bodies, with great ease,
and I hope intelligible enough, there being nothing in the _notion_ of
colour, or in the suppos'd production, but is very conceivable, and may be
possible.

The greatest difficulty that I find against this _Hypothesis_, is, that
there seem to be more distinct colours then two, that is, then Yellow and
Blue. This Objection is grounded on this reason, that there are several
Reds, which _diluted_, make not a Saffron or pale Yellow, and therefore
Red, or Scarlet seems to be a third colour distinct from a deep degree of
Yellow.

To which I answer, that Saffron affords us a deep Scarlet tincture, which
may be _diluted_ into as pale a Yellow as any, either by making a weak
solution of the Saffron, by infusing a small parcel of it into a great
quantity of liquor, as in spirit of Wine, or else by looking through a very
thin quantity of the tincture, and which may be heightn'd into the
loveliest Scarlet, by looking through a very thick body of this tincture,
or through a thinner parcel of it, which is highly _impregnated_ with the
tinging body, by having had a greater quantity of the Saffron dissolv'd in
a smaller parcel of the liquor.

Now, though there may be some particles of other tinging bodies that give a
lovely Scarlet also, which though _diluted_ never so much with liquor, or
looked on through never so thin a parcel of ting'd liquor, will not yet
afford a pale Yellow, but onely a k
