 tis. H. The enlarged area extending to the navel in the forward direction, as far as 

 the cardiac area (C). The costal arch is indicated by the dotted line. The dog was 

 of medium size, but the liver weighed 3 kilos. 



Marked reduction in the size of the liver is sometimes in- 

 dicated by a decrease in the size of the area of hepatic dulness. 

 In these cases in the smaller animals the liver can be felt from 

 the costal arch only, the firm consistency and uneven surface 

 can, however, be appreciated.

 the end of the disease there may be edematous swelling of the 

 abdominal wall and legs.
