As the horse breathes only through the nose, it is important that the openings into that cavity should be free, and capable of dilating sufficiently to allow of the passage of a large volume of air when the animal is put to his speed. The expanded nostril is a striking feature in the blood horse, especially when he has been excited and not overblown. What a sudden effect is given to the countenance of the hunter, when his ears become erect, and his nostrils dilate, as he first listens to the cry of the hounds, and snorts and scents them afar off! And the war-horse—“the glory of his nostrils is terrible!” The following anecdote, related by Professor Kügler, of Halle, proves both the sagacity and the fidelity of the horse:—A friend of his, riding home through a wood on a dark night, struck his head against a branch of a tree, and fell stunned to the ground. The horse immediately returned to the house they had left, and which was now closed, for the family had gone to bed. He pawed at the door until some one rose and opened it, and then he turned about; and the man, wondering at the affair, followed him. The faithful and intelligent animal led him to the place where his master lay senseless. A still more interesting incident, of a similar kind, occurred in this country:—A little girl, the daughter of a gentleman in Warwickshire, playing on the banks of a canal which runs through his grounds, fell into the water, and would in all probability have been drowned, had not a small pony, which had long been kept in the family, plunged into the stream, and brought the child safely to land. Mr. Jesse gives an instance of what may fairly be called the sensibility of the horse, and his keen perception of danger. A friend of his was riding a horse one day in India, attended by a spaniel which had long been its companion. The dog ran into some long grass, and came out crying and shaking its head; the horse, contrary to his usual custom, not only avoided the dog, but showed the utmost dread of his coming near him. The dog soon died, and upon examination it was found that he had been bitten in the tongue by a venomous snake.
