Splenic fever; wool sorter's disease; splenic 

 apoplexy; malignant pustule; anthracemia; my-

 older ones, but the mor- with Diluted Fuchsin Solu- 



tality even in adults- 

 is very great. 



The diagnosis is determined by the postmortem 

 findings; the "blackberry spleen" differentiating 

 it from blackleg. 



The usual channel of infection is through the
