Whenever it is possible, the medicine to be administered should be mingled with a portion of food, and the animal thus cheated or coaxed into taking it; since many instances are on record, in which the pig has ruptured some vessel in his struggles, and died on the spot, or so injured himself as to bring on inflammation and subsequent death. Where this cannot be done, the following is the best method: Let a man get the head of the animal firmly between his knees--without, however, pinching it--while another secures the hinder parts. Then let the first take hold of the head from below, raise it a little, and incline it slightly toward the right, at the same time separating the lips on the left side so as to form a hole into which the fluid may be gradually poured--no more being introduced into the mouth at a time than can be swallowed at once. Should the animal snort or choke, the head must be released for a few moments, or he will be in danger of being strangled. CATARRH. This ailment--an inflammation of the mucous membranes of the nose, etc.--is, if taken in time, easily cured by opening medicines, followed up by warm bran-wash--a warm, dry sty--and abstinence from rich grains, or stimulating, farinaceous diet. The cause, in most cases, is exposure to drafts of air, which should be guarded against. CHOLERA. For what is presented concerning this disease, the author is indebted to his friend, G. W. Bowler, V. S., of Cincinnati, Ohio, whose familiarity with the various diseases of our domestic animals and the best modes of treating them, entitles his opinions to great weight. The term "cholera" is employed to designate a disease which has been very fatal among swine in different parts of the United States; and for the reason, that its symptoms, as well as the indications accompanying its termination, are very nearly allied to what is manifested in the disease of that name which visits man. Epidemic cholera has, for several years past, committed fearful ravages among the swine of, particularly, Ohio, Indiana, and Kentucky. Indeed, many farmers who, until recently, have been accustomed to raise large numbers of these animals, are, in a great measure, disinclined to invest again in such stock, on account of the severe losses--in some instances to the extent of the entire drove upon particular places. Various remedies have, of course, been prescribed; but the most have failed in nearly every case where the disease has secured a firm foothold. Preventives are, therefore, the most that can at present be expected; and in this direction something may be done. Although some peculiar change in the atmosphere is, probably, an impelling cause of cholera, its ravages may be somewhat stayed by removing other predisposing associate causes.
