The lateral measure of the posterior limb, from the point of the patella, to the lateral and salient part of the ham, to the right of the articulation of the tibia with the trochlea.
The perpendicular height of the articulation above named above the ground.
The distance from the point of the arm to the angle formed by the junction of the head and neck.
The distance from the summit of the withers to the junction of the neck with the thorax.
5. Twice this last measure (C)[43] gives almost:
The distance of the summit of the withers to the tip of the patella.
The distance of the point of the elbow to the summit of the crupper or the posterior angles of the ilia.
[43] The proportions given in the two paragraphs 6 and 7 are, under another form, the same as those pointed out in paragraph 2, with this difference, that in this latter they are more clearly expressed.
6. Three times this measure, plus a half-width of the pastern, the equivalent of two heads and a half, will give:
The height of the body, taken from the top of the withers to the ground.
