Tuberculosis. 427 



were completed in three hours, and others have named instances 

 of marking animals for shipment and giving certificates of testing 

 where no tuberculin had been used and no examination beyond 

 the most cursory glance had been made. This might be expected 

 of some non-gradnates, registered on a basis of alleged practice, 

 shamefully ignorant of veterinary medicine and conscious of their 

 false position, and some educated veterinarians thus placed at a 

 disadvantage may have been tempted to follow suit, but it can 

 only end in personal disgrace and an inevitable extension of 

 tuberculosis. Begotten in a legislative wrong and nourished by 

 moral weakness, it can only grow into greater evil. Unfortu- 

 nately such unworthy actions throw discredit on the very name 

 of sanitary police. To avoid the evil every one aspiring to the 

 responsible work of testing cattle should be thoroughly examined 

 as to fitness and licensed to practice under a heavy penalty for 

 neglect or malpractice. 



Feeding Hogs on Fresh Offal from Abattoirs. It has been a 

 common practice, especially in country districts, to turn the raw 

 offal of slaughterhouses to pigs, and as the tubercle is usually 

 concentrated in internal organs, the hogs become infected in large 

 numbers. In public institutions which slaughtered their own 

 meat I have found the hogs all but universally tuberculous. The 

 danger is only slightly lessened when the hogs are fed raw 

 butcher and kitchen scraps in swill. It suggests the compulsory 

 boiling of all swill or garbage containing raw meat. 



Feeding Calves and Hogs on infected Milk. Though it has been 

 repeatedly shown that the majority of moderately tuberculous 

 cows do not yield infected milk, yet in every tuberculous herd, at 

 irregular intervals, one or more are attacked with tuberculosis of 

 the mammae, and the drinkers of the milk take in the tubercle 

 bacilli. This will happen in the most strictly supervised tubercu- 

 lous herds, while in those that are less carefully managed, the 

 milk that is considered unfit for human consumption is fed to pigs 

 or calves. In one dairy, I found that the calves, all fed in this 

 way afterward reacted under the tuberculin test, while the follow- 

 ing year the crop of calves, though fed on the milk of the same 

 diseased cows, with this dffierence that the milk had been first 

 heated to 180 F., without exception grew up healthy, and not 

 one reacted under the tuberculin test.
