the other, from outside to outside. 



The horizontal measurement of the crupper taken between

 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 tuber- 

 osity 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. 



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* (G) gives : 



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 

 th^ withers. 



The lateral width of the posterior limbs near the hams. 



The space or distance of the forearms from one ars\ to the
