REMEDY FOR PHREN1TIS. 265 



ifestation of acute febrile symptoms. Either the mem- 

 branes of the brain or the cerebral substance itself may 

 be first attacked. In the former case there is always 

 good reason to fear the extension of this process toward 

 the material of the brain. 



When the coverings of the brain are inflamed, spasms, 

 pain, and delirium are shown. The ox is violent, champs 

 the teeth, scrapes, stamps, paws, charges at objects which 

 may be near, displays irregular movements and more or 

 less extreme convulsions. Sometimes these symptoms make 

 their appearance at the first onset of the attack, and the 

 loss of nerve power, the dull and stupid look, the more 

 or less marked paralysis, the loss of sensation, resulting 

 from the extension of inflammation to the brain itself, 

 come on later. 



The disorder is peculiar to hot countries and hot sea- 

 sons, especially if there be a sudden change from cold to 

 heat. Working oxen and the plethoric are the most lia- 

 ble to it. A blow on the head, fracture of the skull, 

 tumors, eating distillery refuse, and perhaps ergotized 

 grasses all seem to be causes. 



Symptoms. — Besides those already mentioned, the ox 

 appears sleepy or foolish ; pulse and respirations tardy ; 

 eyes red and wild looking; head and horns hot; tem- 

 perature increased, &c. 



Remedy. — Bleed freely; cold water to head. Purge, 

 even with croton oil. Hydrocyanic acid subcutaneously. 

 In many cases it is better to slaughter. 



For doses, see pages 13 to 29.

Is peculiar to young and debilitated animals, and may 

 result from lack of blood or certain forms of blood dis- 

 ease. Cattle suffer from gastric vertigo (not unlike epi- 

 lepsy), and they may have epilepsy, it is said, as a result 

 of long sea voyages or rheumatism. The animal bellows.
