In many of these forms (Fig. i6) no distinct nucleus can be demonstrated, the cell consisting of a mass of protoplasm in which are scattered numerous deeply staining granules. Many of these granules stain intensely with haematoxylin and other "nuclear" dyes; like chromatin, they resist the action of peptic digestion, and in at least one case (the bacterium- like AcJironiatium, according to Schewiakoff, '93) they have the power of division like the chromatin-granules of higher forms.
