Thus, if any individual be characterized by the development of the nutritive system, this harmonic rule of nature demands not only that, as in the Saxon-English, the Dutch, and many Germans, the trunk shall be large, but consequently, that the other two portions, the head and the limbs, shall be relatively small; that the calvarium shall be small and round, and the intellectual powers restricted; that the head shall, nevertheless, be broad, because the vital cavities of the head are large, and because large jaws and muscles of mastication are necessary for the supply of such a system; that the neck shall be short, because the locomotive system is little developed; that it shall be thick, because the vessels which connect the head to the trunk are large and full, the former being only an appendage of the latter; that the lower limbs shall be both short and slender; that the calves of the legs shall be small and high;[45] that the feet shall be little turned out, &c., &c. So also, if any individual be characterized by the development of the locomotive system, the harmonic rule demands, not only that the limbs shall be large, but, consequently, that the other two portions, the head and the trunk, shall be relatively small; that the calvarium shall be small and long, and the intellectual powers limited; that the head shall be long, because the jaws and their muscles are extended, &c., &c. So likewise, if any individual be characterized by the development of the thinking system, the harmonic rule demands, not only that the head shall be large, but, consequently, that the other two portions, the trunk and limbs, shall be relatively small; that the head shall not only be large, but that its upper part, the calvarium, shall be largest, giving a pyramidal appearance to the head; that the trunk and limbs, however elegantly formed, shall be relatively feeble, the former often liable to disease, the latter to accident, as we have seen in the most illustrious examples, &c., &c. It must be borne in mind, however, as already explained, that there may be innumerable combinations and modifications of these characteristics; certain greater ones, nevertheless, generally predominating. Such, doubtless, was the harmonic method of the Greeks; whether, by them, it was thus clearly founded on anthropology, or not. It is curious that several writers, and Winckelmann among the rest, should have adopted a triple division of the body--without, however, duly founding it in anthropology. Thus Winckelmann says "the entire body is divided into three parts, and the principal members are also divided into three. The parts of the body are the trunk, the thighs, and the legs!"--a distribution and division founded neither in nature nor in truth. That the Greeks were more or less aware of the principles here stated, though their writings have not descended to us, is proved by their idealizations founded upon them.
