Like the late William Percivall, whose works on veterinary subjects remain a monument to his memory, the author has encountered but a single case of this description; it was in a matured but not a very aged animal. The report was, that a year ago it had been attacked by influenza; the lid then enlarged, and the near cheek had been wet ever since. Referring to the pages of Percivall's "Hippopathology," the author procured a thin, elastic probe, about twelve inches long; the horse being cast, and an assistant holding the upper lid, the probe was introduced at the inner corner of the eye, by the lower opening to the duct; the entrance was easy enough, but the passage was soon obstructed; then the probe was inserted at the opening of the duct within the nostril. The way in this direction was longer, but the end came at last, without any good being effected. Next, a syringe being charged, the fine point was introduced up the nasal termination of the duct, the power of the jet effectually removing every impediment; the water streamed through the upper openings, and the horse was sent home cured. The writer saw the animal six months subsequent to the operation; it was apparently in excellent health, and obviously in amended condition. The owner said the horse soon got well after it reached home; but, being pressed to say how great a duration "soon" represented, he rejoined "_about_ six weeks, _perhaps_." Three months afterward, however, the horse was once more brought with "watery eye," and again operation was successful. The proprietor then received back and soon sold the creature, which being past the age when horses are most valuable, seemed likely to become an expensive retainer. CHAPTER III. THE MOUTH--ITS ACCIDENTS AND ITS DISEASES. EXCORIATED ANGLES OF THE MOUTH. Let no man punish a horse for want of obedience; the sole use of the creature and its only delight is to obey. Let no person abuse it for having a hard mouth, or for not answering to the rein. Man had the formation of the mouth, and its condition can be no fault in the possessor; the horse's pleasure is the gratification of its master. Observe the antics of the nag thoroughly trained and perfectly up to the rider's point of jockeyship. Does not every fiber seem to quiver with excess of happiness? There is a tacit understanding between man and horse; the pretty arts and graceful prancings of the animal tell how joyful it is made by the conviction that it is sharing man's amusement. But let the equestrian dismount, and another, above or below the horse's educational point, assume the saddle, that understanding no longer exists. The harmony is destroyed; there is no intelligence between horse and man. All the playfulness disappears; the entire aspect of the animal is changed, and it sinks to a commonplace "ugly brute."
