than usual. The pulse is frequent, hard, and small, and 

 respiration is accelerated. The animal swallows with 

 difficulty, and when the lips are separated, saliva flows 

 freely from the mouth. Obstinate constipation exists 

 from the first. Perfect quiescence soothes and calms the 

 sufferer, but he is acutely sensitive to the slightest noises, 

 which prove a barrier to recovery. 



Treatment. — Perfect rest and freedom from annoyance 

 of all kinds must be secured ; allow plenty of nutritious 

 drinks, free ventilation, comfortable clothing, &c. If the 

 jaws will admit, give a strong aperient No. 3, combined 

 with belladonna, hyoscyamus, &c. Poultice or foment 

 existing wounds, and remove dead or dying tissue, using 

 one of the sedative extracts already named for medicat-

 the rectum alternately, prussic acid, atropine, amyl-nitrate, 

 &c, or use the above-named extracts as electuaries.

 or cats already suffering from the disease. It is denoted 

 in some animals by unusual excitement, perspiration,

 and convulsions appear in paroxysms, and the creature 

 savagely gnaws the original wound. Swallowing is inter- 

 fered with, paralysis comes on, and he dies from exhaus-

 frenzy ; the animal does little else than bite the original 

 wound, he lapses into a comatose condition, and falling 

 paralysed, sinks, and dies. 



Treatment is of no avail. 



Hysteria is the development of unusual excitement in 

 mares at or about the period of oestrum. It is attended 

 by violent spasms, the hind-legs being drawn so rigidly 

 that the toes only rest upon the ground. Highly nervous 

 animals will kick, bite, and rear, discharging a quantity 

 of fluid from the vagina, and are quite unmanageable,
