Yes: Many Persons consider it as a Contexture of Bones, Flesh, Vessels and Entrails, which they explain in four several Treatises, whereof the first is call'd _Osteology_, for the Bones; the second _Myology_, for the Muscles; the third _Angiology_, for the Veins, Arteries and Nerves, which are the Vessels; and the fourth _Splanchnology_, for the Entrails. But lastly, the most clear and perspicuous of all the Divisions of the Body of Man, is that which compares it to a Tree, whereof the Trunk is the Body, and the Branches are the Arms and Legs. The Body is divided into three _Venters_, or great Cavities, _viz._ the Upper, the Middle, and the Lower, which are the Head, the Breast, and the lower Belly. The Arms are distributed into the Arms properly so called, the Elbow and Hands; and the Legs in like manner into Thighs, Shanks, {12} and Feet: The Hands being also subdivided into the _Carpus_ or Wrist, _Metacarpium_ or Back of the Hand, and the Fingers; as the Feet into the _Tarsus_, _Metatarsus_, and Toes. This vision is at present follow'd in the Anatomical Schools. * * * * * CHAP. V. _Of the Skeleton._ _Why is Anatomy usually begun with the Demonstration of the Skeleton, or Contexture of Bones?_ Because the Bones serve for the Foundation Connexion, and Support of all other Parts of the Body. _What is the Skeleton?_ 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 {13} _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.
