With the desire to ascertain the chemical composition of the pigment of common rorquals, the writers have at first trade a study of the adhesion of pigment with the following results. 1. As the adhesion drug of the pigment of oil, bentonite was most superior followed by Faller's earth. As it is difficult to extract the pigment of bentonite after its adhesion, it is decided to use Faller's earth in the future as the adhesion drug. 2. It is discovered that it is possible to adhere the pigment of oil almost perfectly, by adding 40% quantity of Faller's earth in the warm oil of 100-105°C. after stirring it for five minutes and leaving it for fifteen minutes in the room temperature, being treated for ten minutes by the centrifugal separator. (5, 000/m) 3. It was further discovered that the adhesion of Faller's earth, even when the acid value and the intensity of colour of whale oil are high, could be decolourized to a certain degree in proportion to the percent amount of Faller's earth added.
