Tendonous sprains are the most common, and the flexor tendons of the fore legs are most frequently affected. Ligamentous sprains are serious injuries, and may occur in any of the numerous ligaments belonging to the joints of the body. The principles of treatment are the same as for tendons. =Symptoms.=--Sprains of tendons and ligaments are manifested by heat, swelling, pain on manipulation, and lameness. =Treatment.=--First reduce the inflammation by rest and constant use of hot fomentations. If the sprain be severe and at the rear part of the fore or hind leg, raise the heel of the shoe on the affected leg an inch or more. All traces of the inflammation having disappeared, apply cold water and linen bandages, and give a little slow exercise. Should the swelling show no signs of subsiding, or the lameness continue after long and careful treatment, firing may be considered, but should only be undertaken by a skilful surgeon. The diet should be laxative. SPRAINS OF BACK AND LOINS. =Treatment.=--Rest; keep bowels open with warm bran mashes and a dose of Glauber salts (½ to 1 lb. sulphate of soda); also 1 drachm acetate of potassa twice a day for ten days. Treat externally with hot fomentations, or blister if necessary. STRANGLES. =Symptoms.=--Sick and off feed, with possibly slight catarrh and feverish symptoms; abscess forms between bones of lower jaw or elsewhere in the group of lymphatic glands; sore throat; difficulty in swallowing; slobbers; unthriftiness; staring coat; loss of condition; dulness and languor. =Treatment.=--Place in cool box with plenty of fresh air; support strength by nutritious food; all kinds of soft and macerated food are good; if constipated, give laxative food and enemas, but no strong purgative must be used; if necessary, ½ pint of linseed-oil, repeated in 24 hours if required. Tonics, such as 20 grains of quinine, or 1 oz. ground gentian, or 1 teaspoonful sulphate of iron, three times a day. Bring swelling to a head by a poultice of flaxseed, carrots, or turnips. If suffocation be threatened, a tube must be placed in the windpipe. This should be done by a skilful surgeon. SUNSTROKE. =Symptoms.=--Manifested suddenly. Animal stops, drops his head, begins to stagger, and soon falls to the ground unconscious. The breathing is with great stertor, pulse very slow and irregular, cold sweats in patches. _In heat exhaustion_ the animal usually requires urging for some time previous to the appearance of any other symptoms; generally perspiration is checked, and then he becomes weak in his gait; breathing hurried or panting; eyes watery and bloodshot; nostrils dilated and highly reddened, assuming a dark purple color; the pulse is rapid and weak, the heart bounding, followed by unconsciousness and death.
