Chap. VI.—Proportion of Members.
The proportion of members is again divided into two parts, viz. equality, and motion. By equality is meant (besides the measure corresponding with the whole), that you do not confound the members of a young subject with those of old age, nor plump ones with those that are lean; and that, moreover, you do not blend the robust and firm muscles of man with feminine softness: that the attitudes and motions of old age be not expressed with the quickness and alacrity of youth; nor those of a female figure like those of a vigorous young man. The motions and members of a strong man should be such as to express his perfect state of health.
