Some of these rounded bodies contain only one, two or four deep staining granules (Fig. 56A), while others contain large numbers of them. It appears that these granule - filled bodies break up into a large number of parts each containing one gran- ule; these become elongated, and finally appear as distinct rods containing the gran- ule at one end.
