Where the cough is of some standing some apply a blister of 

 biniodide of mercury ointment, and administer ^oz. iodide of potassium, 

 loz. iodide of sulphur, 2oz. cinchona bark, a teaspoonful given in 

 the food every other day. Where the horse is but slightly affected, 

 but appears rather weak, intimately mix together loz. of powdered 

 camphor with lib. of honey, of which give a table-spoonful every 

 morning ; and at night administer a ball containing -l^dr. of iodide 

 of iron. Continue this treatment until a cure is effected. 



Again : Buy 1 pint linseed oil and 2oz. nitre (sweet spirits) ; give 

 (with a horn) half of each one day, and the other half -pint and loz, 

 the next. 



CRACKED HEELS. 



In acute cases remedial measures must be used internally rather 

 than externally. The following are the most marked symptoms 

 of the disease : — The horse's condition is good, but the skin and 

 coat is harsh and rough, the skin under the fetlock joint at the 

 back of the leg contains a few angry looking cracks, whilst the 

 heels are puffy and hot. The horse runs evidently in great pain. 

 Place the animal in a loose box, but do not give too much litter. 

 Let the food be of easy digestion, and not too much of it. Give at 

 first, for three days, bran maskes, and then a mild dose of physic, 

 after which feed on oats (bruised), carrots, or green food. Give 

 nitrate of potash one drachm, and sulphur half an ounce, every 

 day until the heat and swelling in the heels subside. This mixture 

 may be given mixed with their food. 



Dress the heels with water bandages, covered over with oil silk, 

 and foment the parts once a day with warm water — not hot — for about 

 an hour. Discontinue the water dressing when proud flesh appears. 

 Now mix corrosive sublimate with four times its weight of flour, 

 and place it on the wounds ; two or three applications, at an interval 

 of two days, will generally work a cure. When the wounds have 

 healed, keep the skin moist by glycerine put on daily, and see that 

 the heels are thoroughly brushed and for some time not washed. 

 Some veteiinary surgeons recommend, after the constitutional 

 remedies have been used and the wounds healed, to apply locally 

 an ointment composed of iodide of potassium one part, with four 

 parts of lard and four of glycerine. It should be well rubbed into 

 the skin morning and night, the horse meanwhile being allowed only 

 walking exercise, in order to avoid the risk of cracking the heels. 

 At the end of a week an ointment of biniodide of mercury should be 

 substituted for the iodide of potassium. The ordinary red ointment,
