324 THE DISEASES OF SWINE. 



pending on the intensity of the fever and the locality 

 of the poison. In some cases the virus seems to expend 

 itself on the serous membranes, causing either inflamma- 

 tion of the peritoneum or pleurisy ; sometimes on the 

 mucous membranes, as shown by bronchitis or broncho- 

 pneumonic congestion and hemorrhage, and enteric (in-

 perforation or rupture of the bowel.

 from its bed and give a piercing cry, the whole body be-

 diseases, similar to each other in regard to causes, mor- 

 bid process, contagiousness, and final termination, but 

 differing very much as to symptoms, seat of morbid pro- 

 cess, course, and duration." 



Swine plague is classed among the incurable diseases. 



APOPLEXY 



Occurs usually in fat hogs. Several forms have been 

 described, but all are chiefly caused perhaps by too much 

 blood and confinement — lack of exercise. The specific 

 blood poison of anthrax may not be present. The dis- 

 eases of pigs to which the term apoplexy is applied, how- 

 ever, partake more of the nature of anthrax than other- 

 wise, especielly in young and growing animals. 



Symptoms. — Eestlessness ; eyes bloodshot; appetite 

 variable ; constipation ; dung and urine scanty. As the 

 animal eats, it suddenly stops, reels, and falls down dead, 

 a great quantity of foam issuing from the mouth. 



Remedy. — As apoplexy is a most fatal complaint, 

 prompt preventive measures should be instituted on its 

 first appearance. Place healthy swine on a low diet; 

 exercise; cleanliness. Give Epsom salt, 2 to 4 oz., cal-
