There will be swelling and heat in the part and lameness. In some cases there will be swelling, but no lameness. If the swelling is hot and tender to the touch, mix half an ounce acetate of lead and two ounces tincture of arnica with one quart of water. Shake up and apply a little to the swollen part three times a day and continue until the heat and swelling disappear. If there should be any swelling after the heat and lameness have disappeared, mix 1 teaspoonful of biniodide of mercury with 4 tablespoonfuls of lard. Rub on a little with the fingers, let it remain on for 24 hours, then wash off with warm water and soap and repeat the blister in three weeks if needed. In cases where there is swelling, but no heat or lameness, the lotion would be of no use, but the above blister should be used as directed. In old or long standing cases of curb, if the animal is not lame, it is best to let it alone, as medicines would be of no service. =DIABETES; PROFUSE STALING.=--In man there are two forms of this trouble seen rather frequently, but among domestic animals only the insipid form is common. It is often simply a sign of some other disease, but not infrequently occurs under similar circumstances; such as certain forms of indigestion, the result of eating musty or damaged feed. The most characteristic symptom, of course, is the frequent urination of liberal quantities of urine. Associated with this is usually an unabating thirst. The animal loses flesh rapidly, the flanks are tucked up, the coat is dull, languid and staring, and great weakness is shown. If not relieved, the animal may die from exhaustion. In the second form of diabetes, the distinguishing feature is the presence of sugar in the urine. If in a working animal it should be laid off from work. Search should be made for the cause of trouble. If any of the food appears suspicious it should be substituted with wholesome food. To relieve the ardent thirst and assist recovery, a teaspoonful of the crystals of iodine should be given in a ball of linseed or other pasty material. It may be desirable to repeat this in three or four days. Also give in the drinking water 4 tablespoonfuls of bicarbonate of soda three times daily. =DIARRHOEA.=--See Dysentery. =DIFFICULT PARTURITION.=--See Obstetrics.
