decreases, and as the quarter increases in size the milk becomes thin 

 and watery with flakes or strings of curdy matter suspended in it 

 until finally what little can be drawn from such an udder or quarter 

 becomes very thick.. In the report of the Research Laboratory of the 

 Royal Veterinary College, London, for the year 1899 {Veterinarian, 

 May 1900) it is stated that one of the negative characters of tuber- 

 culosis is that the diseased quarter never bursts or discharges matter. 

 Of the value of the tuberculin test as a diagnostic for tuberculosis 

 there is a conflict of opinion among scientific men, it having been 

 found that an animal although not affected with tuberculosis may 

 react. This has been definitely proved in a number of cases after the 

 animals have been slaughtered. In many affections of the lungs and 

 liver — hydatids, actinomycosis, and other similar diseases- — as also in 

 inflammation of the udder, this reaction has been found to take 

 place. At the instigation of Professor Bang, the Danish Government 

 supplied tuberculin and supervision gratuitously for some years. 

 Friedberger, who states tuberculin is not to be regarded as a specific 

 diagnostic agent for tuberculosis, adds however that it may be used 

 with advantage for diagnostic purposes when selecting animals for 

 breeding, and as a prophylactic for combating disease in large 

 herds.
