_The length of the crupper_, taken from the superior point of the anterior angle of the ilium to the tuberosity of the ischium, forming the point of the buttock. _The width of the crupper or of the haunches_, taken from the inferior points of the angles of the ilia. _The height of the crupper_, viewed laterally, taken from the summit of the posterior angles of the ilia to the point of the patella, the leg being in a state of rest. _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: [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. _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. 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. _Its length_, taken from the point of the arm to the point of the buttock inclusive. 7. =This same measure, plus the entire width of the pastern=, gives: _The total length of the body_, taken accurately. 8. =Two-thirds the length of the head= (D) will equal: _The width of the chest_, from the tip of one arm to that of the other, from outside to outside. _The horizontal measurement of the crupper_ taken between two verticals, of which one forms a tangent to the buttock, and the other passes through the summit of the crupper and touches the tip of the patella. _The third of the length of the hind-quarter and of the body_ taken together, as far as the vertical from the withers, touching the elbow. _The anterior length of the hind-limb_, taken from the tuberosity of the tibia to the fold of the ham. 9. =One-half of the length of the head= (E) is the same as: _The horizontal distance from the tip of the arm_ to the vertical line from the summit of the withers and touching the elbow. _The width of the neck_, viewed laterally, taken from its insertion in the trough of the jaw to the roots of the first hairs of the mane, on a line which forms with the superior contour two equal angles. 10. =One-third of the entire length of the head= (F) gives: _The height of its superior part_ from the summit of the forelock to a line which passes through the most salient points of the orbits.
