[44] That is to say, two-ninths of the whole length of the head.
[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:
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.
[46] That is to say, one-sixth of the total length of the head.
