 common intestinal inflammation. Therefore, 

 in these two cases, the characteristic lesions of 

 the typhus, if they must be localized in the 

 intestine, were, so to speak, absolutely wanting.

 inflamed, if in the third the small intestine was 

 congested, and if, lastly, in the cow the large 

 intestine showed ulcerations, we could not in

These facts struck us with great surprise, 

 for we were far from suspecting them. We 

 hoped, on opening the intestine of these 

 animals, which had certainly all died of the

In fine, in this epizootia the intestinal lesions
