• At the preparation of whale oil, the author carried out the experiments under equal cenditions except that each of samples had previously been added with increasing amounts of porphyrinic substances, hemin (Hm) or methyl ester of protoporphyrin (PME). The results obtained were as follows: (1) The color of whale oil is characterized by the amount of porphyrinic substances, viz. the color is deepened with the increase of added substances. (2) It was found that, the higher the coloration of whale oil is, the larger its content of pyrrolic compound. (3) The test of heating of porphyric substances experimentally in hot water the pyrrolic compound is not yielded. From these results, the author presumed that porphyric substances usually present in raw blubb ?? r set free pyrrolic compounds, and the latter influences to the coloring of whale oil stock ?? when they are activated by oil.
