Part 35 (1/2)

=The Head, Front View= (Fig 110)--If, to continue our exaard the head froreatest width at A, B, the extreme points of the orbital arches

This width is 22 centiain equal to:

A, C, from one arch to the nape;

A, D, from one arch to the middle of the face

D, E, froin of the lips

From the auditory canal, G, to the maxillary spine, F, is the sains of the lips, E, or, better, to the end of the teeth

[Illustration: FIG 111--THE SAME FIGURE AS FIG 110, ON WHICH WE HAVE MARKED BY SIMILAR LINES THE PRINcipaL MEASUREMENTS WHICH CORRESPOND THERETO

Distance which separates one of the orbital arches from that of the opposite side, and the dimensions which equal it; distance which separates the auditory meatus from the maxillary spine, and the dimensions which equal it; distance which separates one maxillary spine from that of the opposite side, and the dimensions which equal it; distance which separates the lip of one side from that of the opposite, and the dimensions which equal it[65]]

[65] See the note relative to Fig 109

The line G, C, from the auditory meatus to the nape, is equal to the sixth of the head, 10 centimetres; the line A, G, froer, and measures 12 centimetres

The distance F, I, comprised between the maxillary spines, is 18 centimetres

It is equal to:

O, O, the distance between the internal angles of the eyes (G and B);

F, R, the distance from the maxillary spine to the superior co nostril (G and B);

F, P, from the nate under the name _salt-cellar_ a depression situated external to the frontal region and above the eye

Frole of the eye, C, O, is the same distance as from this latter point to the commissure of the lips, O, T; and from the maxillary spine to the upper lip F, S (G and B)

The distance apart, T, T, of the two coives, very nearly, the distance from the superior border of the orbital arch to the base of the ear or the auditory meatus In the state of rest, the outer limit of the separation of the nostrils does not exceed the width of the knee;[67] we frequently find the same distance intercepted above the nape by the tranquil ears In the figure (Fig 110) we have intentionally represented them directed in a different plane, in order to show that when the pinna is turned backward, it none the less preserves the contour of bracket for of the subject, and characterizing in repose the interior curves of the ear

[67] We reiven by veterinarians to the region occupied by the carpus

The extrehtly exceeds that of the nostrils; on many heads of harmonious proportions this distance is found to be the half of A, B

In order not to interrupt the course of the preceding exposition, we decided to withhold till afterwards soested to us by certain of the proportions which are there indicated

The proportions in question are important--we may even say that they are fundamental, for they have for object the relation which exists between the length of the head, the height of the body, and the length of the latter

We have already seen that, according to Bourgelat, the length of the head is contained two and a half tith of the body, from the point of the arm to the point of the buttock; and, also, two and a half tiht round (see p 265) We saw afterwards that M Duhousset, having adopted these proportions, pointed out, further, that the saain found equally to exist froht which Bourgelat considered as being of less extent

There results, then, from the latter proportions, which we have just recalled, this interesting fact: that they sin, the placing in position of the horse, on the condition always that this latter be always viewed directly on one of its lateral aspects
