_The width of the head_ below the lower eyelids. _The lateral width of the forearm_, taken from its anterior origin to the point of the elbow. 11. =Two-thirds of this length=[44] (G) gives: [44] That is to say, two-ninths of the whole length of the head. _The distance of the point of the elbow_ above the plane of the lower surface of the sternum. _The depression of the back_ in relation to the summit of the withers. _The lateral width of the posterior limbs near the hams._ _The space or distance of the forearms from one ars_[45] to the opposite. [45] We call the region where the superior and internal part of the forearm is joined to the trunk the 'ars.' The space between the ars of one side and the ars of the opposite side is called the 'inter-ars.' 12. =One-half of the third of the entire length of the head=[46] (H) equals: [46] That is to say, one-sixth of the total length of the head. _The thickness of the forearm_, viewed from the front, and taken horizontally from the ars to its external surface. _The width of the crown of the fore-feet_ whether from one side to the other, or from before backwards. _The width of the crown of the hind-feet_, from one side to the other only. _The width of the posterior fetlocks_, taken from the front to the origin of the spur. _The width of the knee_ seen from the front. Note: this measure is a little too large. _The thickness of the ham._ Note: this measure is a little under the mark. 13. =One-fourth of the third of the length of the head=[47] (I) gives: [47] That is, one-twelfth of the length of the head. _The thickness of the canon of the fore-limb_: that of the hind-quarter is a little thicker. 14. =One-third of this same measure=[48] (K) equals: [48] That is, a ninth of the length of the head. _The thickness of the fore-limb close to the knee_ in its narrowest part. _The thickness of the posterior pasterns_, viewed laterally. 15. =The height from the elbow to the fold of the knee= (L) is the same as: _The height from this same fold to the earth._ _The height from the patella to the fold of the ham._ _The height from the fold of the ham to the crown._ 16. =The sixth part of this measure= (M) gives: _The width of the canon of the fore-limb_, viewed laterally, in the middle of its length. _The fetlock_, viewed from the front. 17. =The third of this same measure= (N) is very nearly equal to: _The width of the ham_, from the fold to the point. 18. =A fourth of this measure= (O) gives: _The width of the knee_, measured laterally. _The length of the knee._ 19. =The interval between the eyes from one great angle to the other= (P) equals: _The width of the hind-leg_, viewed laterally, from the cleft of the buttocks to the inferior part of the tuberosity of the tibia. 20. =One-half of this interval between the eyes= (1/2 P) gives: _The width of the posterior canon-bone_, viewed laterally.
