GALL STONES IN SHEEP.
Calculi are very rare. One described by Morton had a brownish yellow color on its surface, and a white color spotted with green internally; it had a bitter taste, colored saliva yellow, and melted when heated, diffusing the odor of musk. It weighed twelve grains and contained 70 per cent. of cholesterin, calcic phosphate and carbonate and the usual biliary elements.
But if spherical calculi are rare, concretions and casts of the bile ducts are common, especially in distomatosis. These are of a yellowish, reddish, greenish or blackish brown, and form granular plates, or veritable cylindroid casts often firmly adherent to the mucous membrane of the duct.
In such cases the walls of the encrusted ducts are hypertrophied and stand out on the back of the liver as white bands diverging from the portal fissure.
Apart from the usual symptoms of distomatosis no special indications have been observed.
Treatment is primarily that for distomatosis, to which the general measures advised for calculi may be added.
