Abstract
Pritchard, Wilkinson, Edisbury and Morton1 have already reported striking disagreement between the biological activity and the absorption at 328 mµ of the concentrates of mammalian liver. As we had formerly used the Carr-Price reaction to a great extent for practical determinations, we were interested in its relation to ultra-violet absorption and to biological activity. We therefore fractionated whaleliver oil and determined the blue colour with trichloride of antimony, the curve for the ultra-violet absorption, and the biological activity, of the various fractions thus obtained.
