However right he may have been in his opinion and practice, in the less enlightened time in which he wrote, (two thirds of a century since,) it may be reasonably presumed, that the many great and astonishing improvements in chemistry, and discoveries in medicine, have thrown some new lights upon the cure of this, as well as of many other disorders, the causes of which are not obscured by the least mist of ambiguity. It is not only clearly ascertained, but generally known, that the jaundice in horses (if attended to upon the first appearance of bilious regurgitation, before the obstructions are become rigidly permanent, constituting an induration of the liver or glands) submits to a course of mild mercurial purging balls properly administered; followed by a few alteratives, composed of ÆTHIOPS MINERAL, incorporated with the PECTORAL CORDIAL BALL. See List of MEDICINES at the End of the Work. JAWS KNOTTED.—Tumefactions under the jaws of horses, for want of a more technical or scientific definition, gave rise to the sublime term of _knotted jaws_; which, however, tends to no distinction, or to any particular description; although tumors may be frequently found there of different kinds, produced by, or arising from, many different causes. Temporary tumefactions of the glands may originate in COLD, and sometimes as suddenly disappear upon a perfect recovery from the cause. Inflammatory tumors form these, as upon the _attack_ of the STRANGLES, or from a foulness and viscidity of the blood; in either of which, relief can only be obtained by speedily promoting suppuration. Glandular tumors sometimes form these, become indurated and stationary, never producing pain or inconvenience during the life of the horse. Others, of a much more critical and dangerous description, make their appearance there also, and are the certain prognostic of FARCY GLANDERS. Some professional knowledge, and judicious discrimination, is absolutely necessary, to distinguish between one and the other in the first instance, the better to regulate (if necessary) the mode of treatment in the next. In all simple tumors arising from cold, local circumstances, or temporary inconvenience, hot fomentation daily, with a sponge or flannel dipt in a decoction of aromatic garden herbs, and afterwards kept in a state of equal temperature with a double flannel and hood, will be found to expedite obliteration, by promoting an early and plentiful discharge from the nostrils. All swellings under the jaws which are painful upon pressure, indicate a tendency to suppuration, which cannot be too soon promoted by such stimulative poultices as may be thought most applicable to the purpose.
