There is scarce a straight bone in the whole body. Almost all of them are not only bent different ways, but have a kind of twist, which in some of them is very graceful; and the muscles annex'd to them, tho' they are of various shapes, appropriated to their particular uses, generally have their component fibres running in these serpentine-lines, surrounding and conforming themselves to the varied shape of the bones they belong to: more especially in the limbs. Anatomists are so satisfied of this, that they take a pleasure in distinguishing their several beauties. I shall only instance in the thigh-bone, and those about the hips. [Illustration: Figs. 64 and 62] The thigh-bone fig. [62 R p. II], has the waving and twisted turn of the horn, 58: but the beautiful bones adjoining, call'd the ossa innominata [Fig. 60 B p. II], have, with greater variety, the same turns and twists of that horn when it is cut; and its inner and outward surfaces are exposed to the eye. [Illustration: Figs. 60, 61 and 63] How ornamental these bones appear, when the prejudice we conceive against them, as being part of a skeleton, is taken off, by adding a little foliage to them, may be seen in fig. [61 B p. II]----such shell-like winding forms, mixt with foliage, twisting about them, are made use of in all ornaments; a kind of composition calculated merely to please the eye. Divest these of their serpentine twinings, and they immediately lose all grace, and return to the poor gothic taste they were in an hundred years ago [Fig. 63 B p. II]. [Illustration: Figs. 64 and 62] Fig. [64 B p. II] is meant to represent the manner, in which most of the muscles, (those of the limbs in particular) are twisted round the bones, and conform themselves to their length and shape; but with no anatomical exactness. As to the running of their fibres, some anatomists have compared them to skains of thread, loose in the middle, and tight at each end, which, when they are thus consider'd as twisted contrary ways round the bone, gives the strongest idea possible of a composition of serpentine-lines.
