ESCHAR—is the prominence remaining upon the cicatrix of an _ill-cured_ wound, or the scab frequently seen to form a projecting apex upon a broken knee; or where some injury has been left to cure itself by an effort of nature, without the least interposition of art. If it is a scab only, and not of long standing, it may in general be brought away spontaneously, by occasional softenings with small quantities of camphorated spermacæti liniment; if, on the contrary, they are rigidly seated, and have acquired a degree of callosity in the nature of a _sitfast_, there is no other mode of cure, but by extirpation with the knife and forceps.
ESTRAY, OR STRAY,—appertain equally to _horse_, _mare_, _bull_, _ox_, _cow_, _sheep_, or, in fact, any head of cattle, who having strayed from its own home, common, waste, or lair, into a strange MANOR, or LORDSHIP, and there found without an owner, is then called an ESTRAY, or _stray_: in which case it is an established custom, sanctioned by LAW, and founded in EQUITY, that such _stray_ is proclaimed, and his or her marks described, by the common crier, in the three next nearest towns on the market-day; and if the stray is not claimed within a year and a day of the time on which it was publicly cried, and fully described, it then becomes the property of the LORD of the MANOR where it was found. If the owner makes the claim within the time limited, he is liable to pay _reasonable charges_ for finding, keeping, proclaiming, &c. An estray must be kept without labour, uninjured, and properly fed, till reclaimed, or the time above mentioned is expired.
EUPHORBIUM,—an article whose acrid and stimulative property renders it only applicable to one medical purpose, and that externally; it constitutes a principal ingredient in the preparation of BLISTERING OINTMENT for HORSES, where its proportion, if managed properly, should be exactly equal with its corresponding article CANTHARIDES, commonly called _Spanish flies_.
EVACUANTS—are such medicines as gently stimulate the intestines, and urinary passages, to a more speedy secretion and expulsion of their excrementitious contents. The term is applicable to both PURGATIVES and DIURETICS; the effect of which is to remove plethora in horses, and to prevent the consequent viscidity of blood; which, when a horse is overloaded in his frame, and the solids too grossly distended, soon displays itself in _swelled legs_, _cracked heels_, cutaneous _scurfy eruptions_, _grease_, _farcy_, or some _one_ of the many ills frequently produced by an accumulation of HUMOURS originating in a corrupt or vitiated state of the fluids, inconsiderately neglected, or probably never attended to. Those who will condescend to dedicate a little time occasionally to the palpable utility of EVACUANTS, either as preventives, or the means of cure, (in a variety of cases,) will never stand in need of a monitor to promote their use.
