some cases. Ulcerations in the center of an area of acute gas¬

of the mucocus membrane of the tongue or a smaller gastric ulcer 
is noted. In these cases the pig shows signs of being very sick. 
The toxin is very virulent and often a small lesion in the mucosa

tract of healthy animals.

manure.

along with hog cholera.

of the great mesenteric artery due to the larva of strongiles 
(diagnosis confirmed by the finding of the worms in the blood 
cogulum), 100 per cent.; gastrophilus hemorrhoidalis larva in the
