3. The continual supply of animal spirits, and their subserviency to sense and motion.[[13]]

4. The nerves, which, though small as threads, remain unbroken, though every one of these small fibres performs its office, and tends to convey strength and motion to the body.

5. The situation of the parts in their most proper place: the internal parts, which would be ruined and destroyed if exposed to the injuries that the external ones are: these are secured in proper inclosures, and so preserved, Job x. 11. Thou hast cloathed me with skin and flesh, and hast fenced me with bones and sinews.
