No. 4.] CATTLE COMMISSIONERS. 463 



until finally, as will be seen by an examination of the reports 

 of the autopsies on the cattle killed, the cases of generalized 

 or advanced cases of tuberculosis have become very scarce. 

 In the following tables the cases of advanced generalized 

 tuberculosis among the cattle killed in 1897, excluding private 

 test work, are compared with the reports for the years 1895 

 and 1896 : — 



Jan. 1 to Dec. 31, 1895. 



Number of animals tested, .... 4,484. 

 Number of animals condemned and found 



diseased, 2,398, or 53.4 per cent. 



General tuberculosis, 784, or 32.6 percent. 



Jan. 1 to Dec. 31, 1896. 



Number of animals tested, .... 7,062. 

 Number of animals condemned and found 



diseased, 4,173, or 59.0 per cent. 



General tuberculosis, 1,051, or 25.1 per cent. 



Jan. 1 to Dec. 23, 1897. 



Total number of animals tested to Dec. 23, 



1897, 9,844. 



Total number of animals condemned to Dec. 



23,1897 5,062, or 51.43 per .cent. 



General tuberculosis to Dec. 23, 1897, . . 183, or 3.61 percent. 



It will be seen that these cases of advanced generalized 

 tuberculosis have become very scarce, and these figures 

 illustrate well the practical benefits resulting from this 

 work. 



In isolated cases or in out-of-the-way places the post-mor- 

 tem examinations are often made by local inspectors. It is 

 not unusual that they have had but little special training in 

 this work, and their opinion as to whether the disease is gen- 

 eralized or not is not always reliable. As a check, there- 

 fore, on their averages, the following table was prepared 

 from those cases where the autopsies were made at Brighton, 

 or by reliable veterinarians ; and it will be noticed that,
