STRANGURY—is a temporary suppression of urine in horses, brought on more by the indiscretion of their riders or drivers, than any morbid affection, or constitutional defect in the horse. It may proceed from a spasmodic stricture upon the sphincter, or the neck of the bladder, occasioned by a too long retention of urine; in continuing an immoderate length of time on the road, or in the field, during which the distrest animal has no opportunity to stale; as well as from a slight inflammation, or tendency to tumefaction, in the kidnies; likewise from calculous concretions in the bladder, jaggy particles of which may irritate, and painfully plug up the urinary passages. Some horses feel great pain when labouring under the suppression, which, when judiciously managed, seldom proves more than a temporary inconvenience. Instantaneous bleeding will sometimes, by unloading the vessels, take off the stricture, and produce instantaneous effect. If the horse is perpetually straining to stale, evacuating only a few drops, or partial dribblings, two or three cloves of a separated onion, or divided garlic, may be insinuated, and left within each side of the sheath; in addition to which, a large sponge, dipt in very warm water, and repeatedly applied to the neighbouring parts, will assist; those local applications proving salutary and expeditious substitutes for the more tedious process of medicine internally administered. In cases of long continuance, and increasing emergency, more commanding means must be adopted; of which DIURETIC BALLS, with a drachm of _camphire_, and a few grains of _opium_ incorporated with each, and periodically repeated, will be found to answer the most sanguine expectation. STRING-HALT.—This defect in a horse is a kind of spasmodic jerk, or sudden twitching of one or other of the hind-legs in action, and has been, in different opinions, attributed to various causes, and probably by none to the right; as there is no one disorder, disease, defect, or imperfection, to which the horse is liable, upon the origin, progress, or cure of which so little has been introduced. It is conjecturally said by some "to be brought on by sudden colds, after severe riding or hard labour, particularly by washing a horse when hot with cold water; a practice too common, and erroneously ridiculous; and that it may also be produced by blows or bruises near the hock." All this may be well upon the score of speculative amusement, but it forms no feature of scientific disquisition. The string-halt, from its appearance, must palpably originate in a previous distortion of some part of the ligamentary junction; or a preternatural contraction, (or partial rupture,) of its muscular appendages; in either or both of which, no regular road to relief can be adverted to without a much greater probability of repentant trouble and mortifying disappointment.
