When pres- ent the mucous membrane of the small intestine shows severe inflammatory changes and developing ulceration in patches or over more extended areas (Carl). The spleen usually presents a normal appearance, but may at times be greatly swollen and softened. Zimmerman, Carl and Bongert describe as rare occurrence sharply circumscribed nodules in the moderately swollen pulp, from a hemp to a millet- seed in size, in which the cut surface appears brownish-red to grayish-red in color, dry and lusterless. In one case of Wyssmann the lesions corresponded to a serofibrinous pneumonia (inhalation anthrax?). 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. 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. After sub- cutaneous or intravenous inoculation the manifesta- tions of the (iisease ap- pear in 24 to 48 hours. Sheep usually succumb in 2 to 3 days to the feeding of large quantities of spores. However, the time of incubation under natural conditions, when the animals take up a con- siderably smaller quan- tity of spores, is undoubt- edly longer. Thus in the experiments of Pasteur, R 0 u X & Chamberland sheep, which were infected mth food grown on in- fected pastures, devel- oped t h e disease only after 10 days. In horses and cattle the time of in- cubation seems to be hard- ly less than 3 days. In horses, cattle and sheep anthrax when
