No. 4.] CATTLE COMMISSIONERS' REPORT. 537 



First. — That, subsequent to June 1, 1896, the use of tuberculin 

 as a diagnostic agent shall be applied to all herds in which one or 

 more tuberculous animals have been found. 



Second. — All owners of herds in which one or more tuberculous 

 animals have been found shall be required to make such reasonable 

 changes in their stables and stable management as shall seem neces- 

 sary to secure to their cattle the conditions known to be essential to 

 health. 



Third. — Full compensation for an animal or animals found to be 

 tuberculous upon any inspection subsequent to the first shall be 

 allowed only when it shall appear that the owner has faithfully en- 

 deavored to carry out the changes which he has been desired to make. 



In 1894 the State of New York appointed a special commis- 

 sion to investigate tuberculosis in cattle in that State, which 

 commission made a report in the latter part of January, 1895, 

 containing several recommendations as to the best met hod to 

 be pursued in the eradication of that disease, all of which are 

 based upon the tuberculin test. 



In a report made by that commission, on Oct. 29, 1895, the 

 following paragraph occurs : — 



The efficacy of tuberculin as a diagnostic agent is of incalculable 

 benefit, although, if followed without due caution, in some cases it 

 will lead to error. By the use of this agent some animals advanced 

 in the disease fail to show any reaction, and in other cases animals 

 not as extensively affected w r ill show higher reaction. In the exami- 

 nations thus far made not an error has occurred, as proven by the 

 autopsies. 



There can be no doubt that the systematic inspection of milch 

 cows and the killing of cattle undoubtedly affected will prevent a 

 large loss to the dairymen and lead to a great saving of infant life. 



Bulletin Xo. 29 of the Pennsylvania State College Experi 

 inent Station, issued in October, 1895, says: — 



All those who have used tuberculin in the United States for the 

 diagnosis of bovine tuberculosis, and have published their work, 

 including Drs. Law, Curtice, Conrow, Faust, Russell, Rice, Schroder, 

 Niles, Fves and Pearson, have expressed themselves as extremely 

 well pleased with the results Avith this agent. 



Remarkable to note, the occasional and scattered opposition to the 

 use of tuberculin comes from those who have never employed it for 

 the diagnosis in cattle.
