As I said, No Part is subject to be sick, but the Stomack; but every several Part of a Human Creature, is subject to Pain; and not only so, but every particular Part is subject to several sorts of Pain; and every several sort of Pain, hath a several Figurative Motion: but to know the different Figurative Motions, will require a subtile Observation: for, though those painful Parts, know their own Figurative Motions; yet, the whole Creature (suppose _Man_) doth not know them. But it may be observed, Whether they are caused by Irregular Contractions or Attractions, Dilatations or Retentions, Expulsions or Irregular Pressures and Re-actions, or Irregular Transformations, or the like; and by those Observations, one may apply, or endeavour to apply proper Remedies: but all Pain proceeds from Irregular and perturbed Motions. CHAP. III. Of DIZZINESS. I Cannot say, _Dizziness_ belongs only to the Head of an Animal Creature, because we may observe, by irregular Drinkers, that sometimes the Leggs will seem more drunk than their Heads; and sometimes all the Parts of their Body will seem to be temperate, as being Regular, but only the Tongue seems to be drunk: for, staggering of the Leggs, and a staggering of the Tongue, or the like, in a drunken Distemper, is a sort of Dizziness, although not such a sort as that which belongs to the Head; so that, when a man is dead-drunk, we may say, that every part of the Body is _Dizzily drunk_. But mistake me not; for I do not mean, that all sorts of dizzinesses proceed from drinking; I only bring Drunkenness for an Example: but, the Effects of dizziness of the Head, and other parts of the Body, proceed from different Causes; for, some proceed from Wind, not Wine; others from Vapour; some from the perception of some Forrein Object; and numbers of the like Examples may be found. But this is to be noted, That all such sorts of Swimming and Dizziness in the Head, are produced from Circular Figurative Motions. Also it is to be noted, That many times the Rational Corporeal Motions are Irregular with the Sensitive, but not always: for, sometimes in these and the like Distempers, the Sensitive will be Irregular, and the Rational Regular; but, for the most part, the Rational is so compliant with the Sensitive, as to be Regular, or Irregular, as the Sensitive is.
