spond with each other, and with the whole. The navelis naturally placed in the centre of the human body, and,if in a man lying with his face upward, and his hands andfeet extended, from his navel as the centre, a circle bedescribed, it will touch his fingers and toes. It is notalone by a circle, that the human body is thus circum-scribed, as may be seen by placing it within a square. Formeasuring from the feet to the crown of the head, andthen across the arms fully extended, we find the lattermeasure equal to the former; so that lines at right an-gles to each other, enclosing the figure, will form asquare. If Nature, therefore, has made the human bodyso that the different members of it are measures of thewhole, so the ancients have, with great propriety, deter-mined that in all perfect works, each part should be somealiquot part of the whole ; and since they direct, that thisbe observed in all works, it must be most strictly attend-ed to in temples of the gods, wherein the faults as well asthe beauties remain to the end of time. It is worthy ofremark, that the measures necessarily used in all buildingsand other works, are derived from the members of thehuman body, as the digit, the palm, the foot, the cubit,and that these form a perfect number, called by theGreek rzXeiog. The ancients considered ten a perfectnumber, because the fingers are ten in number, and thepalm is derived from them, and from the palm is derivedthe foot. Plato, therefore, called ten a perfect number,Nature having*formed the hands with ten fingers, and alsobecause it is composed of units called fAovuhg in Greek,which also advancing beyond ten, as to eleven, twelve,&c. cannot be perfect until another ten are included,units being the parts whereof such-numbers are composed.
