In Lyons out of an average of 36,000 animals slaughtered 

 annually, the number of cases of actinomycos'is was 69 in 

 1895, ^'^d 63 in 1896. Lingual localization was rare. In the 

 abattoir of Troy, Morot observed 19 cases out of 4,185 

 slaughtered cattle, and from January, 1898, to September of 

 the same year, ten cases, of which one was of the lungs and 

 nine of the head. 



In Germany, maxillary actinomycosis is common in Siles- 

 ia, and maxillary and lingual localizations are seen in Fran-_ 

 conia, Palatinate and Bavaria. Degenerate changes of the 

 pharynx and parotids are found in 5 per cent of the cattle 

 of the districts at the mouth of the Elbe. The disease is fre- 

 quent in Denmark, Sweden, Italy, Russia and England. Can- 

 .ada and Chili are also considerably infected. 



ANNOTATION. 



Frequency of Actinomycosis in the United States. — Actinomycosis 



is a fairly common disease throughout the Mississippi Valley, with the ex- 

 ception of the Upper Ohio Valley, where it is seldom encountered. It is 

 found in the Mountain states, on the Pacific Coast and throughout the South. 

 The Eastern states have fewer cases than any other part of the continent. 

 In 1903 the Bureau of Animal Industry condemned 824 carcasses and 837 

 parts of carcasses, affected with actinomycosis, out of a -total of 6,134,410 

 cattle inspected in stock yards and abattoirs. During the same year 32 car- 

 casses and 44 parts were condemned out of a total of 21,793,738 hogs in'- 

 spected. — L. A. M.
