LXXXVI. If it is replied to this, that in every defluxion which is somewhat violent, although we do not feel what may be properly called pain in the head, we at least perceive a heaviness in it; which renders that organ unfit for its operation. I confess that this is so, but to the confession, shall beg leave to add two remarks. The first is, that this is not a symptom peculiar to fluxions, for that the same thing happens in many other disorders; but the generality of physicians do not conclude from hence, that those diseases originate in the head. Secondly, neither is this heaviness or inaptitude, peculiar to the head, for upon observation, you will find that fluxions and many other disorders also, have the same effect upon the other members of the body. Whoever is affected with a violent defluxion, either on the throat, the breast, the stomach, or any other part, will find that his whole body, and every member of it, is more heavy and listless, than when he is in good health; and that all his limbs are less fit for action; and that they all with a very little exercise of them, become soon tired. Thus we have no reason to attribute a heaviness as peculiar to the head, in the attacks of fluxions, when we see it is common in those attacks, to all the other members of the body; and it has been for want of making this reflexion, that the world have conjectured all defluxions were derived from the head. A DISPLAY of the INTELLECTUAL FACULTIES OF THE VARIOUS PEOPLE, With REMARKS on the TALENTS of the DIFFERENT ONES. SECT. I. I. There is no doubt, but the different temperament of air in countries, induces a sensible diversity in men, brutes, and plants. In plants, the difference is so great, that the same which in one country is innocent and salutary, in another is noxious and poisonous, which, as we are assured, is the case with the Persian apple. The diversity between brutes, is not less than that between plants, both with respect to their size, fierceness, strength, and other qualities; but besides what is obvious and clear to the observation of all men in this matter; we are assured there are countries, where many sorts of animals, degenerate totally from the characteristic property of their species. If we are to believe Lucianus, Macedonia produces serpents, so social to the human race, that they will play with children, and gently apply their mouths to the nipples of women’s breasts to suck their milk; and as Louis de Marmol informs us, in Gruregra a mountainous country in the kingdom of Fez, the lions which are very numerous, are so tame and so timid, that the women with sticks in their hands, beat and drive them about like so many domestic dogs.
