The thoroughbred horse is well proportioned, his ears are small and in constant motion, his bones massive, his cheeks meagre, his nostrils wide as the throat of a lion, his eyes bright, black, and level with the head,[20] his neck long, his chest full, his withers prominent, his loins well knit, his haunches strong, his fore-ribs long and the hinder ones short, the belly hollow, the croup rounded, the upper part of his legs long like an ostrich's and furnished with muscles like a camel's, his hoofs black and of a uniform colour, his hair fine and abundant, his flesh firm, his tail very thick at the dock but loose at the extremity. Looked at in front he is like unto the peak of a lofty mountain. Looked at from behind, he seems to lean forward as if he would prostrate himself. Looked at from the side, he shows himself robust and well set up. To sum up: he should have four points broad, the front, the chest, the croup, and the legs;—four points long, the neck, the upper part of the legs, the belly, and the haunches;—four points short, the loins, the pasterns, the ears, and the tail. All these qualities in a good horse, say the Arabs, prove firstly that he has real blood in him, and secondly that he is certainly fleet of foot, for his form combines something of the greyhound, the pigeon, and the _mahari_, or riding camel.[21] The mare ought to take from the wild boar its courage and breadth of head; from the gazelle, its grace, its eyes and mouth; from the antelope, liveliness and intelligence; from the ostrich, its neck and swiftness; from the viper, the shortness of its tail. A thoroughbred horse (_hôor_)[22] may be known by yet other signs. For instance, he cannot be prevailed upon to eat barley out of any other nosebag than his own. He so loves trees, verdure, shade, and running water, that he will neigh for joy on seeing them. Seldom does he drink until he has troubled the water, and if the conformation of the ground prevents him from doing so with his feet, he will kneel down and do it with his mouth. He is continually shrivelling his lips; his eyes are in constant motion; alternately he pricks up and lowers his ears, and turns his neck to the right or left as if he wished to speak, or to ask for something. If to all these signs a horse adds sobriety of disposition, his owner may deem himself the possessor of a pair of wings. It has been remarked that a horse that is a fast galopper has the head firmly set on, and the transverse apophysis of the atloïd very protuberant. "He has horns," say the Arabs.
