JAPANESE CATTLE AND TUBERCULOSIS 



141 



autopsies 116 cases of tuberculosis, amounting to 46.4% of the 

 total. Of the tuberculosis patients, 20 (17.3%) were under 18 years, 

 96 (82.2%) were more than 18 years; among these patients she 

 found 90 (77.6%) who presented lesions showing primary pulmonary 

 tuberculosis, 12 (10.34%) who had primary intestinal tuberculosis. 

 Among the latter 6 were more and 6 less than 18 years. Basing 

 the statement upon this paper, it may be said that the occurrence 

 of primary intestinal tuberculosis is not rare in Japan either among 

 adults or children, although cow's milk is employed but little by us 

 for the nourishment of children. 



The table on the preceding page refers to districts in which man 

 suffered from tuberculosis, but his cattle were free from it (the years 

 considered are from 1896 and 1903); they are the districts Mikata 

 and Osaka at Tasima in Hiyogo-Ken; these districts possess only 

 native cattle. 



The following table shows the number of cases of tuberculosis 

 (perlsucht) among the slaughtered cattle found during the years 

 1901 to 1903 in five large cities : 



TABLE V. 



It must be remembered that for a long time neither Tokio 

 nor Yokohama have possessed any purely native cattle; it is highly 

 probable that the tuberculosis animals mentioned in the foregoing 

 table as native animals belonged in reality to mixed races, inas- 

 much as we have mixed races which resemble the native animals 

 so closely that even an experienced veterinary physician cannot 

 distinguish between them. 



The examination of bovines (inclusive of the mixed races and 

 the imported cattle) for tuberculosis (perlsucht) which has been 

 carried on in Japan since last September and up to March of this year 

 through tuberculin injections and other methods of examination, 

 has given the following results:
