CLUB, _s._ A heavy stick; the name of one of the suits of cards; the shot or dividend of a reckoning; an assembly of good fellows. CLUSTER, _s._ A bunch, a number of things of the same kind growing or joined together; a number of animals gathered together. CLUTCH, _s._ The gripe, grasp, seizure; the paws, the talons. CLYSTER, _s._ An injection into the anus. Clysters of broth, gravy, or gruel, will afford a very considerable quantity of nourishment: a small proportion of opium, as twenty drops of laudanum, may be given in each, to assist in retaining it within the bowels. _Astringent_ clysters, as starch, rice-water, alumine whey, infusion of red roses, or of oak-bark, are useful in violent loosenesses. _Purging_ clysters may be made of veal or mutton broth, with a portion of salt or moist sugar added: the effect may be still further quickened by adding castor oil or Epsom salts. Clysters are very easily administered to dogs, and no apparatus is so convenient for the purpose as the patent syringe of Reid: a good domestic apparatus is found in the common pipe and bladder also. The liquid used should be warm, but not hot; the quantity from three ounces, to six or eight, according to the size of the dog, &c.: the pipe should be greased previously to its introduction, and the tail held down a minute or two after its removal. * * * * * In flatulent colic it is essentially useful, and it is from this circumstance being too little known, or not attended to, that flatulent colic sometimes terminates in inflammation, and death. (_See_ CARMINATIVES.) In suppression or retention of urine, or in difficulty of staling, a clyster is the best remedy that can be employed. In short there is scarcely a disease to which horses are liable, in which clysters may not be advantageously employed, either as a principal remedy, or as an auxiliary to others. The clyster syringes commonly employed are worse than useless, because they sometimes prevent a clyster being given when it is absolutely necessary, especially in flatulent colic. The clyster-pipe and bladder is the only effectual apparatus I have seen. The pipe should be one inch in bore, and fifteen inches in length. The quantity of liquid employed should be five or six quarts, and consist only of warm water, with half a pound of salt dissolved in it. There is sometimes difficulty found in introducing the pipe, generally from hard excrement in the straight gut; sometimes, however, from the bladder being distended with urine. In such cases patience and care are necessary to exhibit the clyster effectually, and it may almost always be accomplished without raking or drawing out the hard excrement with the hand; there is no objection, however, to this operation, and when a clyster-pipe is not at hand, it must be employed as a substitute for a clyster. (_See_ RAKING.) The simple emollient clyster should be thin gruel, or warm water only. The anodyne or opiate
