blood, as in women when blood regurgitates into the intestines due to retained menses: in those mutilated in some limb, in internal ulcerations, and in the flux of hemorrhoids. They become white from the admixture of phlegm or pus; black and shining from the aforementioned blood in the liver, or from melancholic juice; variegated from different humors driven into the intestines; sharp and biting from sharp and biting humor.

37. Dry intemperance of the intestines and the whole body imbibes all moisture, whence the excrements are rendered arid, odorless, and hard; obstruction follows this hardness.

38. Organic disease, for example:
If thick and viscous phlegm fills the folds of the stomach and intestines and induces smoothness, as in Lientery, the egestions become liquid and frequent, retaining the color and odor of the food. Another symptom follows this frequency of egestion, namely, the prostration of strength.

39. If crude humors are retained too long in the stomach and intestines, they easily putrefy due to indigestion; hence, an intense stench.

40. In children and adolescents, worms are often generated from putrid humors by the heat of the intestines, which are mixed into the excrements during egestion.

41. Intestines that are twisted, or persistently obstructed, or concreted by symphysin adhesion/growing together, cause the feces to be carried upward and rejected through the stomach and mouth, as in eileō ileus/obstruction or chordapsus a severe intestinal colic.

42. Obstruction of the mesenteric veins not extracting the juicy parts of the chyme is likewise a cause of liquid and chylous excretion.

43. Obstruction of the bile duct is the cause of white feces, as in jaundice, just as obstruction of the spleen is the cause of black ones.

44. Resolution or relaxation of the muscles of the rectum is often the cause of involuntary dejection, especially in children.
