Sec. 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.

Sec. 30. Thus far had his Observations brought him about the end of the
Third Seventh Year of his Age, _viz_. when he was One and Twenty Years
Old. In which time, he had made abundance of pretty Contrivances. He
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
Strings as were fit for that purpose. He learn'd the making of these
threads from the use which he had made of the Rushes before. He made
Awls of sharp Thorns, and Splinters of Cane, sharpned with Flints. He
learn'd the Art of Building, from the Observations he made upon the
Swallows Nests. He Builds himself a Store-house and a Pantry, to lay up
the remainder of his Provision in: and made a Door to it of Canes
twisted together, to prevent any of the Beasts getting in, during his
absence. He took Birds of prey and brought them up for Hawking; and kept
tame

Poultry for their Eggs and Chickens. He took the tips of the Buffalo's
Horns and fastned them upon the strongest Canes he could get, and Staves
of the Tree _Alzan_ and Others; and so, partly by the help of the Fire,
and partly of sharp edg'd St
