Medicaments, _Gallen_ shewes in the
first Booke of his simple Medicines, and the seventeenth Chapter,
bringing the example of Milke; in which, three substances are found,
and separated, that is to say, the substance of Cheese, which hath the
vertue to stop the Fluxe of the Belly; and the substance of Whay,
which is purging; and Butter, as it is expressed in the said _Gallen_,
_Cap. 15._ Also we finde in Wine which is in the Must, three
substances, that is to say, earth, which is the chiefe; and a thinner
substance, which is the flower, and may be called the scum, or froath:
and a third substance which we properly call Wine; And every one of
these substances, containes in it selfe divers qualities, and vertues;
in the colour, in the smell, and in other Accidents.

_Aristotle_ in the fourth Book of the Meteors and the first Chapter,
treating of Putrefaction, he found the same substances; and in the
second Chapter next following, where he that is curious may read it.
And also by the Doctrine of _Galen_, and of _Aristotle_, divers
substances are attributed to every of the mixt under one and the same
forme and quantity; which is very conformable to reason, if we
consider, that every Aliment be it never so simple, begets, and
produceth in the liver, foure humours, not onely differing in temper,
but also in substance; and begets more or lesse of that humour,
according as that Aliment hath more or fewer parts corresponding to
the substance of that humour, which is most ingendred. And so in cold
diseases, we give warme nourishment; and cold nourishment, in hot
diseases.

From which evident examples, and many others, which we might produce
to this purpose, we may gather, that, when we grind and stir the
_Cacao_, the divers parts, which Nature hath given it, doe
artificially, and intimately mixe themselves one with another; and so
the unctuous, warme, and moist parts, mingled with the earthy (as we
have said of the steele) represses, and leaves them not so binding, as
they were before; but rather with a mediocritie, more inclining to the
warme, and moist temper of the Aire, then to the cold and dry of the
Earth; as it doth appeare when it is made fit to drinke; that you
scarce give it two turnes with the Molinet when there riseth a fatty
scumme: by which you may see how much it partaketh of the Oylie part.

From which doctrine I gather, that the Author of _Marchena_, was in an
errour, who, writing of _Chocolate_, saith that it
