THE LIVER AND PANCREAS 263 



known. Parasitic disease of the liver is one of the epizootic diseases 

 of sheep, and common in the ox, but rare in the horse. The parasite 

 occupies the bile-ducts, which become practically occluded. 



In India, calcareous degeneration of the liver is one of the most 

 common affections of this organ, and throughout the tropics generally 

 liver disorders are very frequent. 



The pancreas is seldom the seat of pathological disturbances ; it 

 may be affected with abscess in strangles or in septic diseases, but 

 such conditions are unrecognisable during life. 



Sugar in urine is described as occurring in dogs ; we have never met 

 with it in horses, though polyuria is a common affection.
