[18] The least thickness of the leg in profile goes 6 times from the sole of the foot to the knee joint and is the same width as the space between the outer corner of the eye and the opening of the ear, and as the thickest part of the arm seen in profile and between the inner corner of the eye and the insertion of the hair.
a b c [d] are all relatively of equal length, c d goes twice from the sole of the foot to the centre of the knee and the same from the knee to the hip.
[28]a b c are equal; a to b is 2 feet?that is to say measuring from the heel to the tip of the great toe.
[Footnote: See Pl. XV. The text of lines 2-17 is to the left of the front view of the leg, to which it refers. Lines 18-27 are in the middle column and refer to the leg seen in profile and turned to the left, on the right hand side of the writing. Lines 20-30 are above, to the left and apply to the sketch below them.
Some farther remarks on the proportion of the leg will be found in
No. 336, lines 6, 7.]
On the central point of the whole body.

In kneeling down a man will lose the fourth part of his height.
When a man kneels down with his hands folded on his breast the navel will mark half his height and likewise the points of the elbows.
Half the height of a man who sits?that is from the seat to the top of the head?will be where the arms fold below the breast, and below the shoulders. The seated portion?that is from the seat to the top of the head?will be more than half the man's [whole height] by the length of the scrotum.
[Footnote: See Pl. VIII, No. 2.]
The relative proportions of the torso and of the whole figure.
333.
The cubit is one fourth of the height of a man and is equal to the greatest width of the shoulders. From the joint of one shoulder to the other is two faces and is equal to the distance from the top of the breast to the navel. [Footnote 9: dalla detta somita. It would seem more accurate to read here dal detto ombilico.] From this point to the genitals is a face's length.
[Footnote: Compare with this the sketches on the other page of the same leaf. Pl. VIII, No. 2.]
The relative proportions of the head and of the torso.
334.
From the roots of the hair to the top of the breast a b is the sixth part of the height of a man and this measure is equal.
From the outside part of one shoulder to the other is the same distance as from the top of the breast to the navel and this measure goes four times from the sole of the foot to the lower end of the nose.
The [thickness of] the arm where it springs from the shoulder in front goes 6 times into the space between the two outside edges of the shoulders and 3 times into the face, and four times into the length of the foot and three into the hand, inside or outside.
[Footnote: The three sketches Pl. XIV, No. 2 belong to this text.]
The relative proportions of the torso and of the leg (335. 336).
335.
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.
[Footnote: See Pl. XVI, No. 1.]
336.
?Top of the chin?hip?the insertion of the middle finger. The end of the calf of the leg on the inside of the thigh.?The end of the swelling of the shin bone of the leg. [6] The smallest thickness of the leg goes 3 times into the thigh seen in front.
[Footnote: See Pl. XVII, No. 2, middle sketch.]
The relative proportions of the torso and of the foot.
337.
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.
[Footnote: See Pl, VII, No. 2, the lower sketch.]
The proportions of the whole figure (338-341).
338.
A man when he lies down is reduced to 1/9 of his height.
