Chapter XXIX.—Symmetry of the Body.

“And mark in this the work of the Designer, how He has inserted the bones like pillars, on which the flesh might be sustained and carried.  Then, again, how an equal measure is preserved on either side, that is, the right and the left, so that foot answers to foot, hand to hand, and even finger to finger, so that each agrees in perfect equality with each; and also eye to eye, and ear to ear, which not only are suitable to and matched with each other, but also are formed fit for necessary uses.  The hands, for instance, are so made as to be fit for work; the feet for walking; the eyes, protected with sentinel eyebrows, to serve the purpose of sight; the ears so formed for hearing, that, like a cymbal, they vibrate the sound of the word that falls upon them, and send it inward, and transmit it even in the understanding of the heart; whereas the tongue, striking against the teeth in speaking, performs the part of a fiddle-bow.  The teeth also are formed, some for cutting and dividing the food, and handing it over to the inner ones; and these, in their turn, bruise and grind it like a mill, that it may be more conveniently digested when it is conveyed into the stomach; whence also they are called grinders.
