No. 4.] CATTLE COMMISSIONERS' REPORT. 511 



conditions are under which it is maintained. Statistics gathered 

 from the returns from slaughter houses are, in the opinion of 

 the commission, of little value in determining the prevalence 

 of the disease ; because, in the first place, under the present 

 law all such diseased carcasses are, if found, destroyed without 

 compensation to the owner; and, in the second place, this 

 examination as at present conducted is, as has been shown, not 

 by any means full. In other words, people will not slaughter 

 animals in licensed slaughter houses in this State if there is any 

 symptom of unhealthiness about them.

 years 1890-9;5, inclusive, show : —

Bollinger, in the Munich " Medical Weekly," states : — 



While it has beeu supposed that neat stock generally are affected 

 with tuberculosis to the extent of § per cent., excepting milch cows, 

 which were supposed to be affected to the extent of f per cent., tin- 

 statistics from the slaughter houses, and by the use of tuberculin, 

 show this disease to be much more widespread. 



In a slaughter house at Berlin, from April 1, 1801, to April 1, 

 1892, 15 per cent, of the 21,000 animals slaughtered were found 

 tuberculous. In the year 1893, in twenty towns in the kingdom of 

 Saxony, out of 6'.), 164 animals, 12,630, or 18.26 per cent., were 

 affected. As showing the percentages of disease among the various 

 classes of animals killed, the following statement is interesting : — 



16,128 bulls killed, 1,947, or 12.07 per cent, infected. 

 23,851 oxen killed, 3,437, or 14.41 percent., infected. 

 28,784 cows killed, 7,175, or 24.92 per cent., infected.
