Rh and motion of the Hand: those of the lower side of every Triangle, to the bending in or clutching of the Fingers, and those of the other two sides, and of the Ellipticks, to the pressure of the Hand or Fingers ends against any body, requiring them to yield to the right and left. Upon these Ridges, the Pores are very providently placed, and not in the Furrows which lie between them. that so their structure might be the more sturdy, and less liable to be depraved by compression; whereby only the furrows are dilated or contracted, the Ridges constantly maintaining themselves, and so the Pores unalter'd. And for the same reason, the Pores are also very large, that they may still be the better preferred; tho the skin be never so much compressed and condens'd by the constant use and labour of the Hand. And so those of the Feet, notwithstanding the compression of the skin by the weight of the whole Body.

These Pores being thus made and secur'd, are a very convenient and open passage for the discharge of the more noxous and perspirable parts of the Blood. Which by the continual use of the Hands and Feet, are plentifully brought into them. Whence it is, that the sweat of the Feet, in many people, is much more offensive than that of any other part of the Body. And that many Hypochondriacal Men, and Hysterical Women, have almost a continual burning in the soles of their Feet, and the Palms of their Hands. Yet not on the top of their Feet or back of their Hands; which being not so much chafed nor kept so warm, are the less disposed to receive the said noxious parts; and are therefore unfurnished with this kind of Pores.
