It is the Analysis or exact Division of all the Parts of a Body, to discover their Nature and Original.
What is requisite to be observ'd by a Surgeon before he goes about to dissect a Body?
Two things; viz. The external Structure of the Body, and the Proportion or Correspondence between the outward Parts, and those that are within.
Why so?
Because without this exterior and general Knowledge, the Surgeon wou'd be often mistaken in the Judgment he is to pass concerning a Dislocation or Wound, inasmuch as it is by the Deformity which he perceives in the Member, that he knows the Dislocation, as it is also by the means of the Correspondence which the outward Parts have with the inward, that he is enabled to draw any certain Consequences relating to a Wound, which penetrates into the Body.
What is a Part?
It is that whereof the whole Body is compos'd, and which partakes of a common Life or Sensation with it.
How many sorts of Parts are there in a Humane Body?
We may well reckon up Fifteen distinct Parts, which are the Bone, the Cartilage, the Ligament, the Tendon, the Membrane, the Fibre, the Nerve, the Vein, the Artery, the Flesh, the Fat, the Skin, the Scarf-Skin, the Hair, and the Nails.
