mercury—half strength, and repeated as needful—to the 
side after removal of the hair. The diet must be 
carefully regulated as well as digestible, and the action 
of the bowels should be largely maintained by enemas 
when the salines arenot employed. Pet dogs recovering 
from the disease may prove useful as previously, but 
animals from which constant or phenomenal work is 
required are rarely capable, and for breeding purposes 
they should not be selected. 
Fatty Degeneration of the Liver is an occasional 
result of hepatitis. In some instances it is enormously 
enlarged, and capable of being manipulated by the hand, 
causing a largely distended abdomen, irregular bowels, 
and anemia, the patient finally becoming excessively 
lean and weak, with all the indications of chronic 
hepatitis. 
| Treatment.—Withdraw food containing fat, and sub- 
stitute fibrine biscuits in moderate quantities, with 
enforced excercise daily. As a treat, give a meal of 
fresh liver, cut up and mixed with the usual food, and. 
as a medicine give ten grains of chlorate of potash twice 
daily for some time. 
Old and worn-out dogs frequently exhibit peculiar 
forms of malignant disease of the liver, spleen, mesentery, 
omentum, &c., which present some of the strangest 
combinations of incurable states. In all such instances 
common humanity suggests their destruction by a painless 
death, as prussic acid or an overdose of chloroform. 
Parasitic Disease of the Liver is due to the presence 
of the fluke Distoma conjunctum in the bile ducts, inducing 
inflammation and numerous smali abscesses. Various 
cystic or bladder forms of parasitism are also common; 
and round worms (/ilaria hepatica) occupy the substance 
as well as the ducts of the liver, leading to the formation 
of cysts in the walls of the intestines. 
Obstruction to the functions of the liver occasionally 
arises from the formation of biliary calculi, or gad/-stones. 
Jaundice is a common sign, with more or less indigestion, 
and acute pain, evidenced by violence during their
