The temperature is raised in proportion to the activity of the 

 tubercular process. 



Tiiberculosis of zvomb and ovaries. — These and their supporting 

 membranes or ligaments are often implicated in the bowel dis- 

 ease giving rise to undue generative excitement. They may also 

 become primarily infected through coition. The affected cow is 

 usually sterile, sooner or later parting with any ovum that may 

 have been impregnated. Later her heats may become more 

 intense and last longer, and never lead to impregnation. The 

 cow spends most of her time wandering around, bellowing for 

 the bull, and neglects to eat or ruminate and wastes away rapidly. 

 There is often a whitish discharge from the vulva. The temper- 

 ature is elevated and general tuberculosis sets in sooner or later. 



Tuberculosis of the liver spleen or pancreas. — The liver is one of 

 the first organs to suffer in infection through the stomach and 

 bowels, and it may be exclusively affected in calves and even in 

 mature animals. Tuberculosis of the liver may be accompanied 

 by impaired appetite and digestion, bloating after meals, and in 

 exceptional cases by jaundice, but often an indefinite ill -health is 

 all that can be detected. Pancreatic and splenic tubercle are 

 marked by a similar obscurit}' of symptoms. It is usually only 

 when the disease begins to be generalized that distinct, objective 

 symptoms are available. 



Tuberc2ilosis of the kidneys aiid bladder may be attended by 

 extra sensitiveness of the loins to pinching and by frequent pass- 

 age of urine, more or less discolored by blood or mixed with pur- 

 ulent matter. Examination of the microscopic blood casts in the 

 urine after having stained them may reveal bacilli. 



Ttiberculosis of the throat. Pharyngeal gla^ids. — This is one of 

 the most common types in cattle. Attention is usually first 

 drawn by a wheezing breathing, the sound manifestly coming 

 from the throat, and the glands around that part are felt to be 

 enlarged, unequal on the right and left sides, or shrunken and of 

 a gristly hardness, or softened and even fluctuating on pressure. 

 The formations above the throat and beneath the first bone of 

 the neck, are particularly liable to undergo this special softening. 

 There is usually a loose gurgling cough, some difficulty in swal- 

 lowing, and a slimy discharge from the mouth. Small tubercu- 

 lar growths may exist on the lining mucous membrane, and this
