of the glands along the lymphatic vessels may become affected, as in 

 farcy, phlebitis, or septic poisoning. 



Treatment. — Fomentation with hot water, the application of cam- 

 phorated soap liniment, or camphorated oil, may i)roduce a revulsive 

 action and prevent suppuration. If there is any indication of abscess 

 forming, poultices of linseed meal and bran made into a paste with 

 hot water should be applied, or a mild blistering ointment rubbed in 

 over the swollen gland. As soon as fluctuation can be felt a free 

 opening must be made for the escape of the contained pus. The 

 wound may subsequently be washed out with a solution of chloride 

 of zinc, 5 grains to the ounce of water, three times a day. 



HYPERTROPHIED LYMPHATICS. 



This is characterized by an enlargement and growth of lymi^hatic 

 glands; the causes are obscure, but they sometimes attain an enor- 

 mous size, and seriously interfere with neighboring organs. This con- 

 dition is sometimes found in the region of the throat above the larynx, 

 and produces wheezing or roaring, b}" j)ressing upon the recurrent 

 laryngeal nerve. It may occur in the bronchial glands of the chest, 

 and interfere with the action of the heart and respiration. The 

 SAvelling is not painful or feverish ; it may be very hard or may be 

 rather soft; occasionally they contain a cheesy deposit or even 

 undergo calcification. A condition almost similar to this may be 

 induced by chronic inflammation. In such cases, however, the gland- 

 ular structure may become lessened, as the result of i^ressure by an 

 increase of fibrous or connective tissue, although a large tumor at the 

 site of the gland remains. This may become gradually absorbed; 

 more often, however, recurrence of inflammation takes place and 

 frequentl}- small abscesses form. 



Treatment. — Repeated blistering with ointment of cantharides 8 

 parts, bin-iodide of mercury 1 part, to be thoroughly mixed and 

 applied once in ten days or two weeks. If this fails, extirpation will 

 become necessar3^ 



LYMPHANGITIS. 



Specific inflammation of the lymphatic structures, usually affecting 

 the hind leg, very seldom a fore leg. This disease is very sudden in 

 its attack, exceedingly painful, acconipanied by a high temperature, 

 and great general disturbance. 



Causes. — Horses of lymphatic or sluggish tempei'ament are j^redis- 

 posed to this affection. It usually attacks well-fed animals, and in 

 such cases may be due to an excess of nutritive elements in the blood. 

 Sudden changes in work or in the habits of the animal may induce an 

 attack. 



Symptoms. — It is usually ushered in b}^ a chill, rise in temperature, 

 and some uneasiness; in a very short time this is followed by lame- 

 ness in one leg and swelling (m the inside of the thigh. The swelling
