No relief being afforded, the pains lengthen, while the intervals of tranquillity become shorter. The action grows more fierce and the aspect more wild. The pawing is more brief, but more energetic; often during its continuance the foot is raised and violently stamped upon the ground. The animal now does not attempt to feed, but stares for a minute at a time, with an inquiring gaze, toward the abdomen. At length, without warning or preparation, the body leaps upward to fall violently upon the floor. The shock is often fearful; but the animal in its torment appears to derive ease from the violence. Being down, it rolls from side to side and kicks about, until one of its feet, touching the wall, enables the horse to poise itself upon the back. [Illustration: THE THIRD STAGE OF SPASMODIC COLIC.] Should relief not be quickly provided, colic soon passes into enteritis. The pulse, from being unchanged at first, then simply quickened by pain, grows harder and more wiry. The intermissions are lost, and though the anguish may for a space be less, yet in its continuity it is more exhausting. On the appearance of colic, the morbid action ought to be immediately counteracted. Aloes in solution is generally administered; such a medicine, unless guarded as before recommended, is by no means advisable. Sulphuric ether and laudanum should be in the possession of every horse proprietor. One pint of each--the two being mixed together, with one ounce of rank oil floating on the top to prevent evaporation or mistakes--will be perfectly safe in any household. The mixture should, however, be well shaken before it is employed: two ounces of the combination in half a pint of water constitutes an excellent colic drink. Give three of these, one every ten minutes. If no improvement be displayed, double the quantity of the active agents and continue the drenches at the period stated: these medicines should be persevered with until the symptoms disappear. Turpentine, as an enema, is an excellent adjunct. Mr. T. W. Gowing, of Camden Town, cured a lingering fit of colic by administering a pint of turpentine mixed with a quart of the solution of soap. The strong liquor of ammonia, diluted with six times its bulk of water and applied by means of a saturated cloth, held to the abdomen in a rug several times doubled, is likewise frequently beneficial. If these means, used simultaneously, produce no amendment in two hours, watch the pulse, for there is most probably something beyond simple colic to contend with.
