Endosarc finely granular, with oneor several non-contractile vacuoles, and many objectsingested as food; such are leucocytes, erythrocytes,eosinophilia, bacteria, starch granules, fscal particles,epithelial cells, etc. (Fig. 5165). The digestion of ery-throcytes is accomplished without e.\cretion of anypigment masses. Reproduction in the human intestine by simple divisionand by schizogony, with the format ion normally of eightdaughter cells. In fission the nucleus undergoes ami-totic division, while in schizogony complicated nuclearchanges are seen with the elimination of a portion of thechromatic subst
