1. The enlarged lymphatic within the jaw. ] Now, both the discharge and the enlargement are generally present during inveterate cold. Animals of this kind are sold to the unwary as sound horses. The vendors believe the quadruped to be glandered, or to be affected with the most terrible of equine diseases; and the purchaser wants knowledge to perceive the contrary. Let, therefore, no man who buys "a captain," (which is the slang for a horse with nasal discharge,) become alarmed, and to some member of the gang from whom it was bought, resell his bargain for a few shillings. Large sums are often made by thus disposing of a diseased animal for a high price; then, directly afterward, frightening the purchaser with a view to buying back at a cheap rate the supposed glandered horse. Always take the animal to the nearest veterinary surgeon. Have the quadruped examined; and, if really glandered, order it to be immediately destroyed. Listen to no offer; but have the order obeyed. A gentleman once attending a sale, bought for a large price a fine black horse. No sooner had the money been paid, than a man came up and informed the purchaser of the real character of his recent acquisition, offering to take the bargain off the new owner's hands for fewer shillings than pounds had just been given. The proposal was indignantly refused. Others came, but all encountered the same answer. The terms were gradually heightened, till double the money expended was tendered. The horse, however, was destroyed; thus a gang of swindlers were deprived of a property which, they owned, had for the last year earned them an easy thousand pounds. Every man, however, must not anticipate so favorable a proposal. The animals mostly are worthless, and would only be rebought for a very trifle; the swindlers, generally, being perfectly indifferent whether their eyes ever again behold a creature which can be easily replaced. NASAL POLYPUS. A =polypus=, when not otherwise distinguished, represents a pear-shaped body, which has little sensation, but great vascularity. It is not malignant, and its growth is generally rapid. By the increase of its weight, the polypus ultimately hangs from the spot where it grew, and becomes pendant by a sort of stalk, formed principally by the blood-vessels enveloped in the membrane which coats the tumor. Such growths are peculiar to mucous tissues, or to all the cavities of the body which communicate with the external air. With regard to the horse, polypus is mostly met with in the nostrils.
