Fraction, and others for Perforation. And thus tho' the Body was _One_,
yet that governing Spirit made use of it several ways, according to the
respective uses of each Member, and the several ends which it propos'd
to obtain.

§ 29. Thus he perceiv'd that there was all this while but _One_ Animal
Spirit, whose Action when he made use of the Eye, was _Sight_; when of
the Ear, _Hearing_; when of the Nose, _Smelling_; when of the Tongue,
_Tasting_; and when of the Skin and Flesh, _Feeling_. When it employ'd
any Limb, then its Operation was _Motion_; and when it made use of the
Liver, _Nutrition_ and _Concoction_. And that, tho' there were Members
fitted to every one of these uses, yet none of them could perform their
respective Offices, without having Correspondence with that Spirit, by
means of the Nerves; and that if at any time it chanc'd that their
passages were either broken off or obstructed, such a Member would be
altogether useless. Now these; Nerves derive this Spirit from the Brain,
which has it from the Heart (and contains abundance of Spirit, because
it is divided into a great many partitions) and by what means soever any
limb is depriv'd of his Spirit, it's Action ceases, and 'tis like a cast
off Tool, not fit for use. And if this Spirit depart wholly from the
Body, or is consum'd or dissolv'd by any means whatsoever, then the
whole Body is depriv'd of Motion all at once, and reduced to a State of
Death.

made himself both Cloaths and Shoes of the Skins of such Wild Beasts as
he had dissected. His thread was made of Hair, and of the Bark of the
Stalks of Althaea, Mallows or any other Plants, which afforded such
