GREASE
.—The GREASE is a disorder particularly affecting the CART or DRAFT HORSES of this country, but is seldom or rarely observed amongst horses of a superior description: its seat is cutaneous, and it first discovers itself by a stagnation of the fluids, and as consequent inflammatory enlargement above and about the fetlock, attended with pain and stiffness, more or less, according to the state of the subject, or the severity of the attack. If proper means are not immediately taken, and judiciously persevered in, a degree of virulence, much trouble, and tedious attendance, unavoidably ensue. The skin, by its preternatural distension, soon assumes a greasy kind of transparency, having an irregular scaly appearance upon the surface, from whence (particularly when put into action) exudes a thin oily ICHOR, which, when become of long duration, is frequently tinged WITH BLOOD, but always of a filthy unctuous property, and greasy to the touch.
As it advances in unrestrained progress, it increases the growth of the hoof around THE CORONET, rendering it of a soft, spongy, and diseased appearance: by the corrosive and fœtid property of the discharge, it soon affects and putrifies THE FROG, which it centrically corrodes, and lays the foundation of CANKER in the FOOT. As it becomes more inveterate, so it proportionally extends itself, and affects the surrounding parts; the small apertures from whence the ferous ichor originally oozed, now become malignant ULCERS, intersected by warty excrescences, and watery bladders of a poisonous appearance. Arrived by length of time, want of care, and probably by the use of improper medicines, or injudicious treatment, at this its second stage, it assumes a more formidable appearance, and every symptom, as well as the limb, continues to increase: what were before only CADAVEROUS ULCERS, now become (in a partial degree) barky eschars, intermixed with growing tetters, from amidst which trickles down, in smoaking heat, the acrimonious sanies, or corrupted matter, which seems to excoriate as it passes, and soon deprives the part of hair; the little that is left serving only as so many conductors, from whence flows in streams the morbid matter, now become so truly offensive, that a horse, in such state, should be separated from others, lest fumes so incredibly noxious should, from the miasma, lay the foundation of disease with horses perfectly sound.
The GREASE may originate in either an INTERNAL or an external cause; as well as be transmitted by hereditary taint (of SIRE or DAM) from one generation to another. An impure and acrimonious state of the blood, unattended to till it has acquired morbid malignity, must display itself in some part; and with horses of the kind described, it generally appears in the extremities, where the CIRCULATION is languid, and the least able to make RESISTANCE. Horses too long continued in MOORS of long lanky grass, intermixed with rushes, or in MARSHY MEADOWS of a swampy soil, where, in the dreary months of autumn and WINTER, their heels are never dry for weeks together, is a very probable foundation of permanent GREASE, or some other CHRONIC complaint, the original cause of which is seldom adverted to, perhaps never recollected. Cutaneous disorders not properly eradicated by MERCURIALS or ANTIMONIALS, but injudiciously thrown upon the circulation by REPELLENTS; the sudden absorption of a plentiful flow of milk, when a colt is taken from the dam; an extreme plethora, with a fizey viscidity of the blood; or any of those causes which too much relax the texture of THE SOLIDS, or impoverish and stagnate THE FLUIDS, may be more immediately or remotely productive of this disease.
External causes also frequently give rise to its appearance; a sudden check to perspiration by change of weather, or change of situation, from one stable to another; or from either to the external air, by turning out to grass from a warm and comfortable stable, unfavourably followed by a succession of cold nights, bleak winds, and rainy weather; washing the heels in hard well water after profuse perspiration; standing too constantly upon stale and filthy dung, for days and nights, impregnated with urine, so evidently prejudicial to the feet and frogs. Horses fed upon grains are remarked to be much subject to the disorder in a slight degree, and this tendency is probably strengthened by a want of cleanly attention, or a little assistance from medicinal counteraction.
Much mischief is frequently occasioned by the rash and injudicious interposition of some illiterate practitioner, who, with a degree of self-cunning, (peculiar to professional ignorance,) piques himself upon the superiority of his art, and confidently proceeds to oppose the predominant efforts which Nature has been induced to make for her OWN RELIEF. Influenced by the deceptive impression of imaginary success, he begins with mild repellents, drying washes, sharp waters, strong astringents, then styptics, and lastly MERCURIAL or VITRIOLIC caustics and escharotics, where having reached the utmost extent of his fertile faculties, he is surprized, but not MORTIFIED, at finding what he erroneously thought a remedy has proved TEN TIMES WORSE than the original disease. The Grease, upon its first appearance, is, by a proper course of medicine, and judicious management, very easily subdued, and radically cured. In its second stage, great PATIENCE and PERSEVERANCE is required; and no expence should be spared, or necessary means omitted. In the third and last, DEATH is preferable to any attempt at cure.
