DISEASES AND INJURIES OF THE LEGS. 219 



predisposition, unaccustomed and prolonged exposure to wet and cold 

 after severe work. 



Symptoms. — Mr. Haycock, who was first to give this disease a sci- 

 entific name, very graphically describes a case of it which occurred in 

 his practice. He says: — *' The horse is standing in the stable on three 

 legs, the left hind limb being held with the foot from the ground. 

 Great anxiety is depicted on the animal's countenance, and he frequently 

 looks round at the limb held up. The respirations are forty-eight per 

 minute; the pulse ninety-six, and hard and cord-like to the touch. The 

 nostrils are dilated to their full extent, and the perspiration rolls in 

 drops from the sides of the abdomen, the shoulders, and the thighs. The 

 affected limb is greatly distended upon its inner surface, from its juDC- 

 tion with the body to the very foot. The lymphatic glands are swollen 

 into large lumps or masses, and towards them, in all directions, run a 

 great number of lymphatic vessels, enlarged to the size of a thick quill. 

 These enlarged vessels exist on the outer as well as the inner side of the 

 limb. The surface of the swelling is covered with a serous exudation : 

 the mouth is dry and clammy; and great desire is evinced for cold 

 water." 



Horses that have once been attacked by lymphangitis are liable to 

 a recurrence of the malady, and generally one attack succeeds another 

 periodically, until the limb assumes an enlarged or distended condition 

 termed elephantiasis. 



Treatment. — Fomentations of warm water to which a little lauda- 

 num has been added, to the affected limb, to reduce the swelling, 

 and the administration of a cathartic: 



Aloes 3 vi. 



Ginger 3 i j. 



Molasses sufficient 



To make one ball 



constitute nearly all the treatment that is required. After the cathartic 

 has operated, diuretic remedies may be given with advantage: 



Powdered digitalis 3 i 



Nitrate of potassium 3 ij. 



Linseed meal, 



Molassess aa sufficient
