DAIRY INSPECTION 159 
If tuberculosis of the uterus is suspected, the sub- 
sacral, sublumbar and internal inguinal lymph-glands 
should be palpated per rectum. These glands are en- 
larged, firm, and often nodular when the uterus is tuber- 
culous. The mesenteric lymph-glands can also be 
examined in the same manner. 
Further information regarding internal conditions 
can be obtained by examining the sclerotic conjunctiva 
and the mucous membrane of the cheeks. These mem- 
branes are pale in tuberculosis and in other chronic debili- 
tating conditions which lead to anemia and hydremia; 
bluish-red (cyanotic) in febrile, respiratory, and cardiac 
diseases and in conditions which interfere with the en- 
trance of air into the lungs; brick-red to dark red, with 
the blood-vessels injected, in hyperemia and inflamma- 
tion of the brain and in conditions which interfere with the 
return of venous blood from the head to the heart (pul- 
monary emphysema, organic heart disease and cardiac 
weakness) ; ecchymotic in anthrax, severe anemia and 
pernicious anemia, and yellow in icterus. 
When symptoms suspicious of tuberculosis are 
present and no definite conclusion can be reached, the 
cow should be tested with tuberculin. 
When catarrhal mastitis is suspected and a definite 
diagnosis cannot be made, the milk should be examined 
by the catalase, leucocyte, or alcohol tests and micro- 
scopically, for streptococci. 
III STABLE PRACTICES 
Attention should be given to the manner in which the 
stable is cleaned, when and how the cows are cleaned, the 
methods of milking and of caring for the milk, the time 
of feeding, character of the feed, and when the litter is 
put down and the material used.
