Coin, s. Money stamped with a legal impression; payment of any kind.

Coistrel, s. obs. A coward hawk.

Colic, s. Is strictly a disorder of the colon; but loosely, any disorder of the stomach or bowels that is attended with pain.

The causes are various: the sudden application of cold either to the surface of the skin when hot, or to the intestines under similar circumstances, in the shape of cold water drunk hastily, and when the horse has been warm; in which latter case, the attack often soon follows. Costiveness will bring it on. Tumours in the mesentery, and strictures in the bowels are also the sources of occasional colic; and when a horse is found to be subject to repeated attacks, something of this kind, or otherwise calculous concretions, may be suspected: and I have known many instances where habitual colic was present, dependent on these causes. Horses long confined to dry food will sometime get it by suddenly gorging themselves with green meat; and with others, a constitutional tendency from some occult cause, gives them a predisposition to it.

The symptoms of spasmodic colic are usually sudden in their appearance, and not marked, as in inflammation of the bowels, by previous indisposition; but the horse is observed to be at once attacked with considerable uneasiness, shifting his position from side to side, pawing his litter, and stamping with his feet impatiently. After a few minutes thus passed, the pain remits, and leaves the horse tolerably easy; while in enteritis no perfect remission occurs, but all is one scene of nearly equable pain and distress. As the colic advances, the remissions are less perfect, and less frequent: the horse now lies down frequently, and on rising shakes himself, looking round to his sides, which occasionally, in desperate cases, he snaps at with his teeth; but more frequently he is seen to strike with his hind feet at his belly, as though determined to remove by force the cause of his pain. In enteritis this acuteness of sensation or violence of temper is seldom seen. When on the ground, it is not uncommon for the horse to roll on his back; sometimes he will remain in this situation a few seconds, or he will roll over; neither of which are usually done in simple inflammation. In colic the pulse is seldom much altered from its natural state, unless the colic have existed some time, when it occasionally presents marks of general irritation, and is not only quickened, but also somewhat hardened. If felt also during the intensity of the paroxysms, it will likewise be often found to be disturbed even in the early stage, but this is momentary only, and ceases on the remission of the pain. The extremities, as the legs and ears, in colic are not often much affected, and they never remain intensely cold for a considerable period, as in enteritis; but the coat stares, and the horse breaks out frequently into cold sweats. In colic, also, relief is obtained by friction and motion, but both aggravate the distress in enteritis. Sometimes he is seen to attempt to stale without effect, at others he stales frequently, with momentary relief.

Treatment.—Having reason to believe that the patient is labouring under simple spasm of the intestines, unmixed with inflammatory tendency, derived from idiopathic enteritis; or symptomatic irritation from inversion, involution, invagination, or intussusception of the intestinal track; proceed at once to administer such one or more of the numberless antispasmodic remedies as custom and experience have warranted the use of. Numerous as these are, there is not one that has not its advocate, and perhaps not one that does not deserve it, so simple are the means sometimes required; and so much is the constitution prone, in some cases, to assist itself or our efforts. While, at the same time, other cases occur, sufficiently obstinate, and sufficiently fatal, to require all our energies, and all our discrimination in the choice of our remedies, I can confidently speak to the antispasmodic qualities of the following, which should one or either of them be given as soon as possible, and repeated in one, two, three, or four hours, according to the violence of the symptoms, if no benefit be apparent from the first dose: for it must be remembered, that what we do we must do quickly, to prevent inflammation, for, of the fatal cases, four-fifths show evident marks of enteritic attack on a post-mortem examination.

1.Ground pepper½ oz.
Spirit of turpentine2 oz.
Tincture of opium1 oz.
Sound ale4 oz. Mix.
2.Spirit of vitriolic æther1 oz.
Tincture of opium (laudanum)2 oz.
Oil of peppermint1 drachm.
Common gin, and sound ale, of each¼ of a pint.
3.Spirit of turpentine2 oz.
Oil of peppermint1 drachm.
Castor oil, and watery tincture of aloes (Mat. Med.) each6 oz.

As a domestic remedy, and one which has relieved at the moment, when other medicines were not at hand, I would recommend the following:—

Ground pepper1 tea-spoonful.
The juice of two or three large onions
Common gin, and sound ale, of each¼ of a pint.

The antispasmodic having been given, the necessity of bleeding should be next taken into consideration: if the case be one of very acute features, I would recommend that it be proceeded with without delay, and, according to the degree of intensity, or duration of the complaint, do it more or less liberally. Extensive bleeding, it should be remembered, is one of the most powerful relaxers of spasmodic constriction with which we are acquainted, and instead of its being an antagonist to the antispasmodic treatment usually adopted, by internal remedies, its relaxant qualities are found to be infinitely increased in efficacy when conjoined with large doses of opium. I have had so many opportunities of witnessing the effect of this combination, that I cannot too strongly recommend it: and although most of the ordinary cases of spasmodic colic will yield to the common stimulant treatment, and many would even go off without any treatment at all, yet bleeding, in mild cases even, is always safe and precautionary against inflammation; and in the more aggravated, it is essentially necessary, both to combat the inflammatory tendency, and to promote the relaxation of the spasmodic irritation on the muscular fibre. It is likewise particularly indicated in these violent or protracted cases, to counteract the irritative qualities of the antispasmodics used, which, though in other instances of simple spasm are innocuous, however large, yet may not prove so when reaction is at hand, or already begun. It should, however, be remembered, that though I advocate bleeding, it is not that useless and non-medical practice of bleeding by the palate or sublingual vessels; and though, with Mr. Peal, I would most strongly condemn violent, and particularly long-continued exercise, yet I have so often experienced the good effects of a brisk trot for ten minutes, that I cannot but recommend its adoption. Friction to the belly is also to be employed, by means of a brush, or if with a heated coarse woollen cloth it will be better; but the practice of rubbing with a stick is, I apprehend, worse than useless, and often hurtful. Fomentations of very hot water are also sometimes singularly efficacious; and in every case we should, by means of the patent syringe, throw up considerable quantities of relaxant clysters; and where costiveness is present, until the bowels are relieved of their fæcal matter, the clysters should be of a mild watery solution of aloes, or, by preference, of a solution of sulphate of magnesia (Epsom salts) in broth, gruel, &c. Afterwards the clysters may be made media of applying antispasmodics to the bowels, as decoction of poppy heads, or even tinct. opii, largely diluted with warm water, &c.—Vide Outlines of Vet. Art.
