_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 causeth Opilations, because _Cacao_ is astringent; as if that astriction were not corrected, by the intimate mixing of one part with another, by meanes of the grinding, as is said before. Besides, it having so many ingredients, which are naturally hot, it must of necessity have this effect; that is to say, to open, attenuate, and not to binde; and, indeed, there is no cause of bringing more examples, or producing more reasons, for this truth, then that which we see in the _Cacao_ it self: which, if it be not stirred, and compounded, as aforesaid, to make the _Chocolate_. But eating of it, as it is in the fruite, as the _Criollas_ eate it in the _Indies_, it doth notably obstruct, and cause stoppings; for no other cause but this, that the divers substances which it containes, are not perfectly mingled by the mastication onely, but require the artificiall mixture, which we have spoken of before.
