It is a gathering together, or Conjunction of all the Bones of the Body almost in their Natural Situation.
From whence are the principal differences of the Bones derived?
They are taken from their Substance, Figure, Articulation, and Use.
How is all this to be understood?
First then, with respect to their Substance, there are some Bones harder than others; as those of the Legs compared with those of the Back-Bone. Again, in regard of their Figure, some are long, as those of the Arm; and others short, as those of the Metacarpium. Some are also broad, as those of the Skull and
Omoplatæ or Shoulder-Blades; and others narrow, as the Ribbs. But with respect to their Articulation, some are joined by thick Heads, which are received into large Cavities, as the Huckle-Bones with those of the Hips; and others are united by the means of a simple Line, as the Chin-Bones. Lastly, with relation to their Use; some serve to support and carry the whole Body, as the Leg-Bones, and others are appointed to grind the Meat, as the Teeth; or else to form some Cavity, as the Skull-Bone, and those of the Ribs.
What are the Parts to be distinguished in the Bones?
They are the Body, the Ends, the Heads, the Neck, the Apophyses, the Epiphyses, the Condyli or Productions, the Cavities, the Supercilia or Lips, and the Ridges.
The Body is the greatest Part, and the middle of the Bone; the Ends are the two Extremities; the Heads are the great Protuberances at the Extremities; the Neck is that Part which lies immediately under the Head; the Apophyses or Processes are certain Bunches or Knobs at the Ends of the Bones, which constitute a Part of them; the Epiphyses are Bones added to the Extremities of other Bones; the Condyli or Productions are the small Elevations or Extuberances of the Bones; the Cavities are certain Holes or hollow places; the Supercilia or Lips are the Extremities of the Sides of a Cavity, which is at the End of a Bone; the Ridges are the prominent and saliant Parts in the length of the Body of the Bone.
