Constituents derived from Food.—Microscopically, indigestibleand undigested constituents of food may be seen (Fig. 42), such asthe framework of vegetable material, sometimes still containingstarch-grannies or remnants of chlorophyll; muscle-fibres, usuallycolored yellow and more or less altered in structure. Elastic-tissuefibres are readily recognized by their double contour and bold out-lines. Connective-tissue fibres of the white fibrous variety can alsogenerally be distinguished ; wheu present in large quantities, how-ever, they are usually indicative of some digestive derangement, un-less they are observed following the ingestion of a meal particularlyrich in meat. Flakes of casein also are seen frequently. Fig. Collective view of the feces. (Eye-piece IT I., objective 8 A.
