system they exert any solvent influence on the concretions. 
Small doses of calomel are more to be relied on, with 
attention to the bowels and regulation of the diet. If the 
animal is emaciated, has fared badly, and been continually 
confined, a new rule should be established, a plain but 
liberal diet allowed, with vegetable tonics, daily exercise, 
and strict attention to cleanliness. 
SPLENITIS. 
Diseases of the spleen have been but little recognised in 
canine pathology, save in post-mortem examinations. 
Splenitis usually occurs in connection with liver disease 
and intermittent fevers. : 
Youatt observes: “In the cases that I have seen, the 
earliest indications were frequent vomiting, and the dis- 
charge of a yellow, frothy mucus. The animal appeared 
uneasy, shivering, the ears cold, the eyes unnaturally pro- 
tuberant, the nostrils dilated, the flanks agitated, the respi- 
ration accelerated, and the mucous membranes pale. The 
best treatment I know is the administration, twice in the 
day, of a ball composed ofa grain of calomel and the same 
quantity of aloes, and 5 grains of ginger. 
“The dog frequently cries out, both when he is moved 
and when he lies on his bed. In the course of three days. 
the yellow mucus is generally disappearing, and the ex- 
pression of pain is materially diminished. 
“If the bowels are much constipated after two days have 
passed, 2 scruples of aloes may be given, and a grain of 
calomel ; frequently injections may also be administered.” 
Enlargement of the spleen may occasionally be both felt 
and seen ; there is more or less pain on pressure, and con- 
stipation and vomiting are generally present. The iodide 
of potassium and iron in scruple doses twice daily, with 
relaxation of the bowels by aloes, is the best treatment L 
am aware of.
