    Anthrax bacilli are found in great numbers in the gelatinous-hemorrhagic con- nective tissue as well as in the swollen lymph glands. On the other hand, they are © only sparingly present in the blood, and in the spleen nodules mentioned they are mostly found in a degenerated form. The feeding of large quantities of spores to domestic fowls usually produces an intense hemorrhagic enteritis, the blood being tarry; and at different times bloody serous infiltration of the subeutis, as well as of the mesentery, moderate swelling of the spleen and spotted discoloration of the liver tissue may be observed. In spite of such changs the bac- teriological findings may be negative, probably because the bacilli have dissolved in the meantime (Hofherr). Symptoms. The time of incubation of anthrax after arti- ficial infection varies from 1 to 14 days, depending to a great extent on the place and intensity of the infection.

In the peracute cases the course of the disease simulates cerebral apoplexy (anthrax acutissimus s. apoplecticus). Well nourished and apparently healthy animals, which, however, were _probably feverish, suddenly go down in the stable or in the pasture and remain lying on the ground in convulsions; the respiration is rattling; bloody foam oozes from the mouth and
