26. SECTIONS OF THE UDDER AND PUBIC LYMPH GLAND OF THE 
COW SHOWN IN ILLUSTRATION NO. 25. 
The numbers denote, 1, longitudinal section of udder; 2, transverse 
section of udder; and 3, section of pubic lymph gland. The udder 
is affected with a diffuse, very acute tuberculosis. The lymph gland 
is many times its normal size, and though it shows no well-marked 
tuberculous lesions, fluid expressed from it was found on microscopic 
examination to be loaded with tubercle bacilli.
