DISEASES OF THE ORGANS OF 0ENEBAT1ON. 513 



XIV. Hysteria. 



This is a peculiar and quite rare nervous condition accompanying beat 

 and manifested, principally, by the voluntary muscles. The jaws champ ; 

 the teeth are ground ; the muscles tremble ; the legs and feet are liable 

 to paw, strike or kick spasmodically ; in short, the mare acts in a generally 

 delirious manner. Sometimes the brain is so much affected that this coo* 

 dition runs on into tetanic convulsions, inflammation of the brain, and 

 death. 



What to do. — Give a quart of raw linseed oil, or else No. 23, and No. 

 52. Repeat the latter every four to six hours, till purgation takes place, 

 when all unpleasant symptoms will usually disappear. 



XV. Abortion. 



When mares abort, it is usually the result of accident or overwork. 

 If compelled to draw too heavy a load, a single extra hard pull is often- 

 times sufficient to produce abortion ; any such accident as slipping, fall- 

 ing, external violence, etc., may likewise bring it about. Usually, all 

 parts come away naturally, without any untoward result other than nerv- 

 ous prostration , and, perhaps, a slight febrile rise in pulse and temper- 

 ature for a day or two aftenvards. 



What to do. — Allow absolute rest for a few days, and give soft feed 

 and chilled water. If any fever follows, give a teaspoonful of saltpetre 

 In the mash, morning and night.
