Qauses. High feeding, inactivity, want of exercise, and the result of 



such diseases as purpura scarlet fever, and diseases the result of pro- 

 found alteration of the blood. 



How to know it. — Debility in the circulation, irregularity and weak, 

 ness in the puUe, lessening of the heart sounds, swe l l ing of the legs and 

 sometimes a general dropsical condition, dilatation, a want of correspond- 

 ence between the heart beats and the stroke of the pulse, appetite irreg- 

 ular and capricious, and the membranes of the mouth and nose a rusty 

 red color. 



What to do. — Humor the appetite with sound, easily digestible food. 

 There is no remedy. Attention to the general health, and an ounce of 

 chlorate of potash twice a day in the food may mitigate s%Tnptoms when 

 more violent than usual. In all heart or arterial diseases give rest, and 

 in fattening stock, do so as quickly as possible. 



VI. Enlargement of the Arteries. 



Dilatation of the arteries (Aneurism), is rarely found. It is a thinning 

 and weakening of the coats of the vessels, sometimes to bursting, causing 

 a pulsating: tumor containing blood. 



Causes. — Severe strains in the vicinity of an artery, blows, kicks, 

 stabs, or weakening from overstretching, as in fatty degeneration. In 

 the mesenteric arteries of horses, they are common from immature 

 worms ( Sclerrt,<<toj7ium equhuim) in the circulation. 



How to know it. — There is a soft, fluctuating, visible tumor if near 

 the surface, which may be reduced by pressure, but which instantly 

 reappears. 



What to do. — Treatment is not successful except when near the sur- 

 face. Then steady pressure by a pad if taken early wiU sometimes cause 

 its disappearance. An animal with enlargement of the arteries is un- 

 sound and should never be bought . The same rule apphes to all diseases 

 of the heart. 



VH. Inflamed Jugular Vein. 



Causw. — This is due, for the most part, to bleeding, and the treatment 

 to which the horse is subjected, or rather lack of treatment immediately 

 after blood-letting. It is not to be attributed to any particular manner 

 of bleeding, or to any awkwardness in its execution and in the closing of 

 the wound. Some horses have a constitutional predisposition to inflam- 

 mation u}X)n any occasion of punctured veins, and the most skillful 

 phlebotomist cannot avoid throwing theoi into this state unless care is taken
