Aluminium in plants has of late drawn attention of many researchers, such as STOCKLASA5). who found the retarding power of the element against the poisoning action of iron and mangan, NEGER1), who found the relation of it to the hardness of fluits-wall, MOLISCH2), that to the colour of blossom, and others. To the nutritional meaning of aluminium in animal body, though studied fragmentally by ROSE and CATHERWOOD6) and MASSATSCH and STEUDEL7), further questions are left yet unanswered. OYA and SHIMADA8) have given the distribution of aluminium in the muscle of some marine animals. The present paper is intended to provide us with the analytical data of the element in food-organisms for fish, determined by the method of WINTER, THRUN and BIRD9). As the existence of iron and other heavy metals disturbed the colorimetry, they were previously eliminated from the materials as sulphide with SH2, after having been ashed. The results are summarised in Table I.
