The quantitative analysis of the fatty acids from the oil (table 1) has followed the general procedure described by T. P. Hilditch et al. (1) Solid and liquid fatty acids separated by lead saltalcohol method was converted into neutral methyl esters (table 2, 3), and these methyl esters were fractionated by distillation under reduced pressure. The results obtained are shown in table 4 and table 5. The composition of fatty acids calculated are shown in table 6. The content of the saturated fatty acids was 10.6% and the unsaturated acids 89.4%. The saturated fatty acids consisted mainly of myristic, palmitic and a little quantity of stearic acids. The unsaturated fatty acids consisted of monoethenoid acids of C20, C18, C16, C22, C14 and a little quantity of C18, C20, C22 acids which were more unsaturated than monoethenoid. This viscera oil showed a considerably different fatty acid composition from that of the head and Jaw oil(3), but the composition resembles to that of the blubber oil(4).
