168 BOVINE PATHOLOGY. 



hours have elapsed. Febrile and general symptoms are 

 present, and in the early stages the patient is excited. 

 The internal temperature is considerably elevated. Next 

 signs of abdominal pain appear, the animal is very uneasy, 

 the pulse becomes rapid, small, and fluttering ; respirations 

 accelerated, and somewhat laboured. There is pain on 

 pressure of the loins, stiffness, and staggering gait ; also a 

 discharge of mucus and saliva from the mouth, and mus- 

 cular twitchings over the body. Rapid debility sets in ; 

 there is a discharge of bloody faeces, and the urine also 

 contains blood. The pulse is lost, and paralysis supervenes, 

 so that the animal is recumbent. Williams speaks about 

 cases of this disorder assuming the characters of remittent 

 fever, and lasting for several days. Convulsions occur in 

 the later stage, and the animal dies generally by necreemia 

 and coma. In all cases death is ushered in by rapid and 

 extreme fall of the internal temperature. 



Treatment. — Curative means have not been found use- 

 ful. We could hardly expect them to be so since the 

 animal is all but dying when we are sent for. Prophy- 

 lactic measures comprise those recommended for anthracoid 

 cases in general. Dogs and pigs have been known to die 

 from consumption of the evacuations. 



Post-mortem examination shows the spleen enormously 

 distended, even to five times its natural size and weight, 

 by the dark blood, which gravitates freely, since the tissue 

 of the organ is broken down. The blood, tissues in general, 

 serous mucous, &c., present the characteristic anthrax 

 lesions, which are especially marked in the bowels. The 

 contents of the intestines and bladder are mixed with blood. 



Texas Fever, Spanish Fever, American Splenic Fever 

 is a form of anthrax endemic in the region of the 

 Gulf of Mexico, whence it is spread through the cattle 

 districts of the United States by contagious influences. It 

 presents several peculiarities, though it closely resembles 

 splenic apoplexy. It differs in the following points, which
