2G6 THE DISEASES OF CATTLE. 



froths at the mouth, and passes feces and urine involun- 

 tarily. Usually the fits soon cease ; the ox rises and soon 

 appears healthy again. Fatten and slaughter. 



APOPLEXY 



Is caused by overdistention and bursting of the blood 

 vessels of the brain and the consequent pressure of the 

 flowing blood on its walls, to fracture of the skull, or to 

 the bursting of an abscess. In a general way the disor- 

 der arises from too much blood and from overdriving and 

 excitement in hot weather while in this condition. 



Symptoms. — These vary in accordance with the seat 

 of the flowing blood. As a rule they are sudden and 

 marked ; looks dull ; reels and falls suddenly ; uncon- 

 scious ; unable to move or feel ; blood vessels of head 

 and neck very full ; heart and lungs are the only organs 

 which exhibit life ; pulse small and thready ; breathing 

 slow, loud, and labored ; body covered with cold sweat ; 

 mouth open and animal breathing through it almost en- 

 tirely; eyes widely opened and rolling and staring; pupils 

 dilated ; convulsive movements may show themselves, but 

 the muscles are usually soft and flaccid, &c. 



Remedy. — Bleed and purge. Strong liniment to loins 

 and spine. If relief does not follow, slaughter. 



PARALYSIS 



May be due to many different causes, namely, exposure 

 in low, damp }3astures, pressure of the fetus on the pos- 

 terior aorta or the iliac arteries which supply the hind 

 limbs with blood, but which may cease after delivery; 

 poisons, lead palsy, for instance ; pressure of tumors on 

 or disease of some part of the nervous system, falls, frac- 

 tures, &c. (See page 51). 



Remedy. — If severe, slaughter. If not, let the animal 

 lie comfortably and be frequently turned to avoid sores.
