CHAP. I. The cause of writing this Treatise of Poysons.
FIVE reasons have principally moved me to undertake to write this Treatise of poysons, according to the opinion of the Anci∣ents. The first is, that I might instruct the Surgeon what reme∣dies must presently be used to such as are hurt by poysons, in the interim whilst greater meanes may bee expected from a Physi∣cian. The second is, that hee may know by certaine signes and notes such as are poysoned or hurt by poysonous meanes, and so make report thereof to the Judges, or to such as it may con∣cerne. The third is, that those Gentlemen and others who live in the Countrey, and farre from Cities and store of greater meanes, may learne something by my labours by which they may helpe their friends bitten by an Adder, madde Dogge, or other poysonous creature, in so dangerous, sudden and usuall a case. The fourth is, that e∣very one may beware of poysons, and know their symptomes when present, that being knowne, they may speedily seeke for a remedie. The fifth is, that by this my labour all men may know what my good-will is, and how well minded I am towards the common wealth in generall, and each man in particular, to the glory of God. I doe not here so much arme malicious and wicked persons to hurt, as Surgeons to provide to helpe and defend each mans life against poyson; which they did not un∣derstand, or at least seemed not so to doe, which taking this my labour in evill part, have maliciously interpreted my meaning.
But now at length, that wee may come to the matter; I will begin at the generall division of poysons, and then handle each species thereof severally: but first let us * 1.1 give this rule; That, Poyson is that which either outwardly applyed or struck in, or inwardly taken into the body, hath power to kill it, no otherwise, than meate well drest is apt to nourish it. For Conciliator writes, that the properties of poyson are con∣trary to nourishments in their whole substance, for as nourishment is turned into bloud, and in each part of the body whereto it is applyed to nourish, by perfect assi∣mulation is substituted in the place of that portion which flowes away each moment.
