In this paper, inorganic substances in the cuttle-fish viscera were determined and the following results were obtained. 1. As to the qualitative analysis, the cationic elements - Cu, Fe, Al, Zn, Mn, Mg, Ca, Na, K-, the anionic elements-Cl, P, S, I-were detected. Besides these, a trace element which seems to be Cd was found. (Table 2) 2. The results of determination of these elements are shown in Table 3. It is noticeable that contents of Zn, Mn, Cu in the viscera of cuttle-fish are higher than those in fish meat and mollusc meat. There seems to be some difference in the contents of other elements among the viscera and meats.
