Expelling of Poyson, or any Malignity in the Body, is, when that Malignity hath not got, or is not setled into the Vital Parts; so that the Regular Motions of the Vital Parts, and other Parts of the Body, endeavour to defend themselves from the Forrein Malignancies; which if they do, then the Malignant Motions do dilate to the Exterior Parts, and issue out of those Exterior Passages, at least, through some; as, either by the way of Purging, Vomiting, Sweating, or Transpiration, which is a breathing through the Pores, or other passages. After the same manner is the expelling of Surfeits, or Superfluities of Natural Humours: but, if the Malignity or Surfeit, Superfluity or superfluous Humours, have the better, (as I may say) then those Irregular Motions, by their Disturbances, cause the Regular Motions to be Irregular, and to follow the Mode; which is, to imitate Strangers, or the most Powerful; the most Fantastical, or the most debauch'd: for it is, many times, amongst the Interior Motions of the Body, as with the Exterior Actions of Men. CHAP. VII. Of Human Digestions and Evacuations. To treat of the several particular Digestive Actions of a Human Creature, is impossible: for, not only every part of Food hath a several manner of Digestive Action; but, every action in Transpiration, is a sort of Digestion and Evacuation: so that, though every sort of Digestion and Evacuation, may be ghest at; yet, every Particular is not so known, that it can be described. But this is to be noted, That there is no Creature that hath Digestive Motions, but hath Evacuating Motions; which Actions, although they are but Dividing, and Uniting; yet they are such different manners and ways of uniting and dividing, that the most observing Man cannot particularly know them, and so not express them: but, the Uniting actions, if regular, are the Nourishing actions; the Dividing actions, if regular, are the Cleansing actions: but if irregular, the Uniting actions are the Obstructive actions; and the Dividing actions, the Destructive actions.
