About the composition of the saturated fatty acids in cuttle-fish oil, only palmitic acid was found by M. Tsujimoto and H. Kimura. The saturated fatty acids were measured by fractional precipitation of Pb salts from ethanol and by steam distillation of the brominated methyl esters* and by oxidation of the methyl esters in acetone with KMnO4. The saturated fatty acids were contained about 25% in fatty acids of cuttle-fish oil and myristic, palmitic, stearic and arachidic acids were isolated by fractional distillation of the saturated methyl esters. Besides, by paper chromatography the small quantities of capric, lauric and behenic acids were recognized, and it is also supposed to contain the very small quantities of caproic and caprylic acids. At the same time, there are many studies about this, but their results are not so sure and detailed as mine.
