Fischers observations with regard to anabaenin canscarcely be reconciled with the published statements of other investigators of theBlue-green Algae. It is possible that anabceniu is identical with the substance containedin the mucus-vacuoles, as that substance is of a carbohydrate nature and the vacuolesare often aggregated around the central body. (2) Cyanophycin granules. These granules were so named by Borzi(86), who considered them as a food reserve. They are identical withthe reserve granules o
