 interference with the flow of bile, but when the stool 

 contains an excessively large amount of fat and fatty 

 acids. S.s, Lead-pencil, fecal discharges of a very 

 small caliber. They occur independent of any general 

 nervousness or local intestinal spasm and cannot be

 colon. [Hemmeter.] S.s, Schafkoth. See S.s, 

 Sheep-dung. S.s, Sheep-dung, the small round 

 fecal masses (similar to the dung of sheep) due to 

 atony of the intestines ; this form of passage may occur 

 in the so-called "starvation" or "hunger" evacua- 

 tion which is found in cases of inanition, e. g., after 

 carcinomatous cachexia, when the intestine becomes 

 very much contracted. [Hemmeter.] S. -sieve of

 thoroughly and conveniently washed, so that undigested 

 remains of food, bits of mucus, concretions, and para- 

 sites are readily brought to view and isolated.
