EXAMINATION 53 sheep-manure, without the existence of any pathologic altera-tion of the intestine. In disease of the intestine the quantity, form, and colorof the feces may be decidedly altered. Instead of a singlestool usually amounting to 100 to 200 grams ( to ), the dejections may be very frequent—10 to 20—andamount to as much as 1000 grams (32 ounces).

Undigested remnants of food (fragments of potato,vegetables, etc.) can be recognized with the naked eye in thesometimes light-colored, sometimes darkly-stained evacuations(see page 31). In biliary congestion the stools are grayish yellow or clay-like; in obstinate constipation they are deep brown or black. Fig. IS.—Simss Wire Speculum. (so-called carbonized stool). In hemorrhage into the lowerportion of the intestine fresh blood may be passed with thedejecta; when the point of bleeding is located higher up, thestools are usually strikingly altered: dark brown to tar col-ored. The latter color is present in stools following gastrichemorrhage. In cholera rice-water, or soup-like, evacuationsoccur: in many forms of enteric catarrh (especially in children)the stools are gall or grass-green colored. While occasional mucous shreds or flocculi are observedin the stools of healthy individuals only when the feces arevery hard and firm, large mitcoiis sJireds are often mixed withthin dejecta, or large gelatinous mucous masses are expelledwith or without feces (colitis, cholera, dysentery, etc.).
