_The width of the fetlock of the fore-limb_, from its anterior summit to the root of the spur. Finally, the difference of the height of the crupper with respect to the summit of the withers. It is certain that the multiplicity of these proportions, and above all the exaggeration of details into which Bourgelat fell in indicating certain of the measures which constitute the bases of some of them, may repel the reader. For this cause we desire to add to the preceding, and also because the question which we are treating would be incomplete without it, the results obtained and published by other more modern authors, and in particular by Colonel Duhousset.[49] [49] E. Duhousset, 'Le Cheval,' Paris, 1881. This author, one of whose constant occupations is the measurement of the different regions of the horse, has the incontestable merit of having drawn attention to this question, and of having strained all his energies in the propagation of the knowledge which until then was little diffused. Among the proportions which he recommends, there are some which are the result of his own observations; whilst others, which he has verified and adopted, are the result of a judicious selection of those given by Bourgelat, which we have just reproduced in the preceding pages. We join thereto also certain indications furnished by MM. A. Goubeaux and G. Barrier,[50] distinguishing these latter by the initials (G. and B.) of their authors (Fig. 107).

Depth from the back to the belly, N, O,[51] the thickness of the body.[52] [51] Look for the points indicated by these letters on Fig. 107, which is related to the proportions which are here discussed. [52] The proportion previously indicated by Bourgelat (see p. 265, paragraph 3). 2. From the summit of the withers to the point of the arm, H, E. 3. From the superior fold of the stifle to the point of the ham, J´, J. 4. From the point of the ham to the ground, J, K. 5. From the dorsal angle of the scapula to the point of the haunch, D, D. [Illustration: FIG. 107.--PROPORTIONS OF THE HORSE (AFTER COLONEL DUHOUSSET).] 6. From the passage of the girth to the fetlock, M, I, or higher in large horses and racers; to the middle of the fetlock or lower for small ones and those of medium size. 7. From the superior fold of the stifle to the summit of the crupper in those specimens whose coxo-femoral angle is very open. This distance is always much less in others (G. and B.).[53]
