in auro latet Essentia. Juxta quod Practicam nobis ad Memoriam
ponimus, ut non obliviscamur, ad hunc modum: Recipe Vinum
vetustissimum & optimum quod habere poteris, calore saporeque ad
placitum, hoc in vas vitreum infundas ut tertiam ejus partem impleat,
& sigillo Hermetis occlusum in equino ventre mensibus quatuor, & in
continuato calore teneatur qui non deficiat. Quo peracto, Hyeme cum
frigus & gelu maxime saeviunt, his per mensem exponatur ut congeletur.
Ad hunc modum frigus vini spiritum una cum ejus substantia protrudit
in vini centrum, ac separat a phlegmate: Congelatum abjice, quod vero
congelatum non est, id Spiritum cum substantia esse judicato. Hunc in
Pelicanum positum in arenae digestione non adeo calida per aliquod
tempus manere finito; Postmodum eximito vini Magisterium, de quo
locuti sumus._
But I dare not _Eleu._ lay much Weight upon this Process, because I
have found that if it were True, it would be but seldom Practicable in
this Country upon the best Wine: for Though this present Winter hath
been Extraordinary Cold, yet in very Keen Frosts accompanied with
lasting Snowes, I have not been able in any Measure to Freeze a thin
Vial full of Sack; and even with Snow and Salt I could Freeze little
more then the Surface of it; and I suppose _Eleu._ that tis not every
Degree of Cold that is Capable of Congealing Liquors, which is able to
make such an _Analysis_ (if I may so call it) of them by Separating
their Aqueous and Spirituous Parts; for I have sometimes, though not
often, frozen severally, Red-wine, Urine and Milk, but could not
Observe the expected Separation. And the Dutch-Men that were forc'd to
Winter in that Icie Region neer the Artick Circle, call'd _Nova
Zembla_, although they relate, as we shall see below, that there was a
Separation of Parts made in their frozen Beer about the middle of
_November_, yet of the Freezing of their Back [Errata: Sack] in
_December_ following they give but this Account: _Yea and our Sack,
which is so hot, was Frozen very hard, so that when we were every Man
to have his part, we were forc'd to melt it in the Fire; which we
shar'd every second Day, about half a Pinte for a Man, wherewith we
were forc'd to sustain our selves._ In which words they imply not,
that their Back [Errata: Sack] was divided by the Frost into differing
Substances, after such manner as their Beer had been. All which
notwithstanding, _Eleu._ suppose that it may be made to appear, that
even Cold sometimes may _Congregare Homogenea, & Heterogenea
Segregare_: and to Manifest this I may tell you, that I did once,
