[XXX.]
MADAM,
Your Author says,[1] it is an ancient Truth, That whatsoever things, meats being digested and cast out by vomit, are of a sowre taste and smell, yea, although they were seasoned with much sugar. But I do not assent to this opinion; for I think that some Vomits have no more taste then pure Water hath. Neither am I of his mind, That Digestion is hastened by sharpness or tartness: For do but try it by one simple experiment; take any kind of flesh-meat, boyl or stew it with Vinegar, or sowre wine, or with much salt; and you will find, that it doth require a longer time, or rather more motions to dissolve, then if you boyl it in fair water, without such ingredients as are sowre, sharp, or salt; also if you do but observe, you will find the dregs more sandy, stony and hard, being drest with much salt, and sharp wine, or vinegar, then when they are not mixt with such contracting and fixing Ingredients. Wherefore, if the Ferment of the stomack hath such a restringent and contracting quality, certainly digestions will be but slow and unprofitable; but Nature requires expulsion as much as attraction, and dilation as much as contraction, and digestion is a kind of dilation. Wherefore, in my judgment; contracting tartness and sharpness doth rather hinder digestion then further it. Next I perceive, your Author inclines to the opinion, That Choler is not made by meat:[2] But I would ask him, whether any humor be made of meat, or whether blood, flesh, &c. are made and nourished by meat? If they be not, then my answer is, That we eat to no purpose; but if they be, then Choler is made so too. But if he says, That some are made, and some not; then I would ask, what that humor is made of, that is not made by meat or food received into the body? But we find that humors, blood, flesh, &c. will be sometimes more, sometimes less, according either to feeding, or to digestion, which digestion is a contribution of food to every several part of the body for its nourishment; and when there is a decay of those parts, then it is caused either by fasting, or by irregular digestion, or by extraordinary evacuation, or by distempered matter, &c. all which, causes sickness, paleness, leanness, weakness, and the like. Again: your Author is against the opinion of the Schools, That the Gall is a receptacle of superfluous humors and dregs: for he says, it has rather the constitution of a necessary and vital bowel, and is the balsom of the liver and blood. Truly, it may be so, for any thing I know, or it may be not; for your Author could but guess, not assuredly know, unless he had been in a man as big as the Whale in whose belly Jonas was three days, and had observed the interior parts and motions of every part for three years time, and yet he might perchance have been as ignorant at the coming forth, as if he never had been there; for Natures actions are not onely curious, but very various; and not onely various, but very obscure; in so much, as the most ingenious Artists cannot trace her ways, or imitate her actions; for Art being but a Creature, can do or know no more then a Creature; and although she is an ingenious Creature, which can and hath found out some things profitable and useful for the life of others, yet she is but a handmaid to Nature, and not her Mistress; which your Author, in my opinion, too rashly affirms, when he says,[3] That the Art of Chymistry is not onely the Chambermaid and emulating Ape, but now and then the Mistress of Nature: For Art is an effect of Nature, and to prefer the effect before the cause, is absurd. But concerning Chymistry, I have spoken in another place; I'le return to my former Discourse: and I wonder much why your Author is so opposite to the Schools, concerning the doctrine of the Gall's being a receptacle for superfluities and dregs; for I think there is not any Creature that has not places or receptacles for superfluous matter, such as we call dregs; for even the purest and hardest Mineral, as Gold, has its dross, although in a less proportion then some other Creatures; nay, I am perswaded, that even Light, which your Author doth so much worship, may have some superfluous matter, which may be named dregs; and since Nature has made parts in all Creatures to receive and discharge superfluous matter, (which receiving and discharging is nothing else but a joyning and dividing of parts to and from parts,) why may not the Gall be as well for that use as any other part? But I pray mistake me not, when I say superfluous matter or dregs; for I understand by it, that which is not useful to the nourishment or consistence of such or such a Creature; but to speak properly, there is neither superfluity of matter nor dregs in Nature. Moreover, your Author mentions a six-fold digestion, and makes every digestion to be performed by inbreathing or inspiration; For in the first digestion, he says, The spleen doth inspire a sowre Ferment into the Meat: In the second, The Gall doth inspire a ferment, or fermental blas into the slender entrails: In the third, The Liver doth inspire a bloody ferment into the veins of the Mensentery, &c. I answer, first, I am confident Nature has more ways then to work onely by Inspirations, not onely in General, but in every Particular. Next, I believe there are not onely six, but many more digestions in an animal Creature; for not onely every sort of food, but every bit that is eaten, may require a several digestion, and every several part of the body works either to expel, or preserve, or for both; so that there are numerous several Motions in every Creature, and many changes of motions in each particular part; but Nature is in them all. And so leaving her, I rest,
Madam,
Your Faithful Friend
and Servant.
