is followed by insensibility, during which life passes 

 away. 



There is no cure for confirmed cases. The only course 

 is to place animals under the care of a qualified veterinary 

 surgeon in the early stages of disease, and, learning the 

 cause, instituting rational treatment in the way of work, 

 food, &c, with the view of preventing the attack in others. 



Apn<ea. — A form of blood poisoning dependent upon 

 an arrest of the functions of the skin. It arises in the 

 horse as a result of a heavy coat of hair, which growing 

 very long and thick during the autumn, and, being im- 

 properly cleaned, is glued together, acting as a covering 

 of soms impervious material, by preventing the essential 

 exhalation of sensible, as well as insensible, perspiration. 

 The conditions are slowly established, general lassitude, 

 unfitness for work, and failing health being the common 

 signs, until they ripen into dulness, paralysis and insensi- 

 bility, which end in death. 



Treatment in the early stages is all important. Remove 

 the coat and substitute dry woollen clothing. Enforce 

 rigid cleanliness of the skin, and the habitations. Rouse 

 the system by diffusible stimulants, as spirits of ammonia, 

 spirits of nitrous ether, &c, with which nux vomica is to 

 be prescribed in conjunction with vegetable tonics, &c. 

 The opinion of a veterinary surgeon should be sought at 

 the outset.

Having their origin in inordinate, impaired, or arrest of function, and remark- 

 able for the development of a septic state — Purpura Hemorrhagica — 

 Azoturia — Malignant sore throat. 



These diseases are the analogues of charbon in cattle, 

 and although the development of a septic poison within 

 the blood is undoubted, they do not rank as contagious
