Conclusion A photometric method has been presented for the determination of the colors of tallows and greases. The relation existing between certain spectral absorption data and the normal visual conception of color has been shown. The method is both comprehensive and flexible and entirely eliminates the personal factor as involved in a visual method of color‐grading, with its attendant disadvantages, variations in individual chromatic conception, ocular fatigue, and the inability of the dichromat to evaluate color. The method inherently permits the devisal of color measuring systems of a continuous and comprehensive character. Several systems of color evaluation for tallows and greases adapted to photometric data derived by the foregoing method have been furnished. It is desired to draw attention to the fact that this technical paper does not possess any official status but is presented by the author with the thought that it offers some original concepts which might provide another and simple approach to the problem involving the color evaluation of oils by means of photoelectric photometry. Indubitably, considerable further investigation, particularly of a cooperative nature, remains to be performed before a final and universally acceptable photometric method is evolved.
