JAUNDICE.—The jaundice is a disorder to which quadrupeds are subject as well as the human species; and notwithstanding the difference in the formation of each, it originates in a similar cause with one as with the other. When HORSES are attacked with it, they are said to have the YELLOWS; which name it also goes by with farmers and country practitioners, when it is observed to make its appearance among what they term "the cow cattle." It proceeds from a partial and imperfect secretion, or temporary obstruction of the gall through the biliary duct, which being compulsively regurgitated, diffuses a tinge of its property through every part of the system, constituting the distinguishing appearance from which the disorder derives its name. When proceeding from this cause, and a proper mode of treatment is adopted in the earliest instance, but little trouble is known to follow, and a certain cure is soon obtained; but should tubercles in, or a schirrosity of, the liver, or an induration of its collateral glandular parts, have proved the cause, more patience, time, and medical perseverance, will be required, before a perfect cure can be expected or obtained. The leading symptoms of this disorder in a HORSE are, a dulness of the head and debility of the body, heaviness about the eyes, head hanging drowsily in the manger, loss of appetite, pulse both languid and low, a laborious respiration, and daily reduction of flesh. Soon after these symptoms successively come on, they are followed by a yellowness of the inside of the eye-lids, the lips, the tongue, and the bars of the mouth; even the urine is of a saffron colour. In this state, from an evident deficiency in the corresponding secretions, and a proportional inaction of the dependent emunctories, nature becomes universally overcharged, and labours under the sluggish debility already described. BRACKEN, who understood this disorder perfectly, and described it most accurately, plainly perceived, the certainty of cure depended entirely upon removing such obstructions as soon as possible after their first appearance, before the disorder had made any progress towards inveteracy or long standing: to effect which, he judiciously recommends purgatives, with a large proportion of ENGLISH SAFFRON and TURKEY RHUBARB. 'Tis true, the great efficacy of the different preparations of MERCURY, as DEOBSTRUENTS, was not so well known in his time, as at the present moment, or the MERCURIUS DULCIS would have been introduced as a powerful assistant upon the occasion. Proceeding in a scientific disquisition of the disorder, he recommends hepatic deobstruents, with soap, salt of tartar, turmeric, soap of tartar, and filings of iron, fully convinced, as he says, of their efficacy, after the most satisfactory and repeated trials.
