lA'MPHAlsGITIS. 



specific inflammation of the h'mphatic structures usually affects the 

 hind leg; very seldom a fore leg. This disease is very sudden in its 

 attack, exceedingly painful, accompanied by a high temperature and 

 great general disturbance. 



CauMS. — Horses of lymphatic, or sluggish, temperament are pre- 

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

 such cases ma}' be due to an excess of nutritive elements in the blood. 

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

 attack. 



Symptam^. — lX is usually ushered in by a chill, rise in temperature, 

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

 in one leg and swelling on the inside of the thigh. The swelling gradu- 

 ally^ surrounds the whole limb and continues on downward until it 

 reaches the foot. The limb is excessively tender to the touch, the 

 animal perspires, the breathing is accelerated, pulse hard and quick, 

 and the temperature may reach 106° F. The bowels earl}' become 

 constipated and the urine scanty. The symptoms usuallj- are on the 

 increase for about two days, then they remain stationary- for the same 

 length of time; the fever then abates; the swelling recedes and becomes 

 less painful. It is very seldom, though, that all the swelling leaves the 

 leg; generally it leaves some permanent enlargement, and the animal 

 becomes subject to recurrent attacks. Occasionally, the inguinal lym- 

 phatic glands (in the groin) undergo suppuration, and pyemia may 

 supervene and prove fatal. In severe cases the limb becomes denuded 

 of hair in patches, and the skin remains indurated with a fibrous 

 growth, which is known by the name of ch-j>Ji<infiat>!s. 



Treatment. — The parts should be bathed freelv and frequently with 

 water as hot as the hand can bear and then fomented with vinegar and 

 water, equal parts, to which add 2 ounces of nitrate of potassa for 

 each gallon. This should be applied frequenth', after the hot water 

 for the first da}'. Afterwards, the leg may l>e dried with a woolen cloth 

 and bathed with camphorated soap liniment. Internally, administer 

 artilicial Carlsbad salts in 2 to 4 ounce doses three times daih'. Feed 

 lightly and give complete rest. This treatment, if instituted early in 

 the attack, very frequentlj- brings about a remarkable change within 

 twenty-four hours.
