CHAP. XLVII. Of the Fourth Kind of Colic.
THis Kind of Colic is occasion'd by Worms, which stick to the Stomach and great Guts, and cause such violent and intolerable Pains, that the tormented Horse is driven to the most desperate Actions, and sometimes lies stretch'd on the Ground as if he were dead.
The Worms or Truncheons, that cause those Gripings, are usually broad, thick, and short, like little Beans of a red Colour: there are others long and white, sharp at both Ends; but these are not so dangerous as the former, and seldom gripe the Horse. These little Worms gnaw and pierce the Guts, from whence proceed the intolerable Pains with which the Horse is tormented: I mean the first Kind of Worms, that occasion all these Disorders, and even somtimes eat Holes thro' the Maw, and kill the Horse.
You may conclude that the Pain proceeds from Worms, when you find 'em among the Horse's Dung: but the red Sort is not easily discern'd, being almost of the same Colour with the Excrements. You may also know that the Horse is troubl'd with 'em, when during the Violence of the Pain he bites his Flanks or Belly, and tears off part of his Skin, as if he were mad; afterwards he will turn his Head, and look upon his Belly, sweat all over the Body, throw himself upon the ground, start up again, and put himself into several unusual Postures.
Since I design afterwards to describe all the various Kinds of Worms that are generated in the Bodies of Horses, I shall here confine my self to the proper Subject of this Chapter.
When a Horse is troubl'd with the Worms, mix half an Ounce of Mercurius dulcis with an Ounce and a half of old Treacle, and make up the whole into three Pills, which must be given in a Pint of Claret. An hour after inject a Clyster of two Quarts of Milk, with the Yolks of six Eggs, and a quarter of a Pound of Sugar, which by its Sweetness will entice the Worms to the streight Gut. The best Mercurius dulcis may be had for fifteen Pence the Ounce. See the Hundred and fifty eighth Chapter, where you will find several ways to destroy Worms, by Purgation, Powders, Potions, &c.
A Gentleman of my Acquaintance having sent to a little Town for half an Ounce of Mercurius dulcis, the Apothecary sent him corrosive Sublimate, which he gave without scruple to his Horse, who dy'd of it; and after his Body was open'd the Disorders caus'd by the Poison appear'd in his Throat and Maw; for the Quid pro Quo was some∣what too strong on this occasion. To prevent such dangerous Cheats, you must make the Apothecary put some of the Mercury on the tip of his Tongue, for that which is truly prepar'd is so free from all manner of Sharpness, that it will not so much as prick the Tongue, and I my self usually taste it, without either Fear or Danger.
