Aceoriliiig to Stroh the milk oljtaineil fi'om the tuherculous qviarters is fre- 

 quently alkaline in reaction, contains an increaseil amount of salts of sodium, 

 chlorine, lime ami phosphorus, the fat is diminished and the milk sugar present in 

 only small quantities or al)sent altogether. The nitrogenous contents consist of 

 jiaraglobnlin and alliumin instead of casein and albumin as in normal milk. 

 Monvoisin also found tlie aciility eonsideraljly reduced (from 1.4 to 2.0 g. of lactic 

 acid — normal contents per liter — to 0.80, 0.24 and even 0.12 g.) which is in contrast 

 to ordinary inflammations of the udiler where the acid content is usually increased 

 on account of decomposition of lactose. The percentage of fat may be reduced 

 from the normal (being instead of 3..5-4..5% only l..'5%). Milk sugar may he 

 almost entirely absent. The freefing tenqiei-atuie remains about the same. 



According to Ostertag the examina-

 lymph glands. 



the lymph glands may be palpated from without and from below (Fig. Ol). These 

 glanils lie in the angle which is formed by the upjjer and posterior liorder of the 

 udder. As a rule the posterior border of these glands does not project beyond 

 the posterior border of the udder. 



To confirm the diagnosis it is advisable to cleanse and disinfect the udder 

 with soap ami water, rinse with alcohol and, with the aiil of a harjioon, remove 

 a jjortlon of tissue from the ali'ected region for Ijacteriological examinations (sec 

 ])p. .ITl and .574).
