_a b c_ are equal to each other and to the space from the armpit of the shoulder to the genitals and to the distance from the tip of the fingers of the hand to the joint of the arm, and to the half of the breast; and you must know that _c b_ is the third part of the height of a man from the shoulders to the ground; _d e f_ are equal to each other and equal to the greatest width of the shoulders.

The Notebooks of Leonardo Da Vinci, Volume 1 — Part 107

The torso _a b_ in its thinnest part measures a foot; and from _a_ to _b_ is 2 feet, which makes two squares to the seat--its thinnest part goes 3 times into the length, thus making 3 squares.

A man when he lies down is reduced to 1/9 of his height.

The opening of the ear, the joint of the shoulder, that of the hip and the ancle are in perpendicular lines; _a n_ is equal to _m o_.

[Footnote: See Pl. XVI, No. 2, the upper sketch.]

From the chin to the roots of the hair is 1/10 of the whole figure. From the joint of the palm of the hand to the tip of the longest finger is 1/10. From the chin to the top of the head 1/8; and from the pit of the stomach to the top of the breast is 1/6, and from the pit below the breast bone to the top of the head 1/4. From the chin to the nostrils 1/3 Part of the face, the same from the nostrils to the brow and from the brow to the roots of the hair, and the foot is 1/6, the elbow 1/4, the width of the shoulders 1/4.
