you something, when I tell you that the Yellowness of
the Mercurial Solution and the Oyl of Tartar is produc'd by the
Precipitation occasion'd by the affusion of the latter of those Liquors,
and that the destruction of the Colour proceeds from the Dissipation of
that Curdl'd matter, whose Texture is destroy'd, and which is dissolv'd
into Minute and Invisible particles by the potently Acid _Menstruum_, which
is the reason, why there remains no Sediment in the Bottom, because the
infused Oyl takes it up, and resolves it into hidden or invisible Parts, as
Water does Salt or Sugar. But when I have told you all this, I am far from
thinking I have told all that such an Inquisitive Person as your self would
know, for I presume you would desire as well as I to learn (at least) why
the Particles of the _Mercury_, of the Tartar, and of the Acid Salts
convening together, should make rather an Orange Colour than a Red, or a
Blew, or a Green, for 'tis not enough to say what I related a little
before, that divers Mercurial Solutions, though otherwise made, would yield
a Yellow precipitate, because the Question will recurr concerning them; and
to give it a satisfactory answer, is, I freely acknowledge, more than I
dare as yet pretend to.

But to confirm my conjecture about the Chymical reason of our Experiment, I
may add, that as I have (_viz._ pag. 34th. of this Treatise) elsewhere (on
another occasion) told you, with Saline Liquors of another kind and nature
than Salt of Tartar, (namely, with Spirit of Urine, and Liquors of kin to
that) I can make the _Mercury_ precipitate out of the first simple Solution
quite of another Colour than that hitherto mention'd; Nay, if instead of
altering the Precipitating liquor, I alter'd the Texture of the Sublimate
in such a way as my Notions about Salt requir'd, I could produce the same
_Phaenomenon_. For having purposely Sublim'd together Equal parts (or
thereabout) of Sal-Armoniack and Sublimate, first diligently Mix'd, the
ascending Flowers being diffolv'd in fair Water, and Filtred, gave a
Solution Limpid and Colourless, like that of the other Sublimates, and yet
an _Akaly_ drop'd into this Liquor did not turn it Yellow but White. And
upon the same Grounds we may with _Quick-silver_, without the help of
common Sublimate, prepare another sort of Flowers dissoluble in Water
without Discolouring it, with which I could likewise do what I newly
mention'd; to which I shall add, (what possibly you'l s
