Abstract
IN earlier papers1, we pointed out the correlation of absorption at 2600 A. with the activity of various B1 concentrates and the probability that the active material is a purine or pyrimidine derivative as indicated by its apparent absorption maximum at this point2,3. The materials discussed in these papers1 were impure concentrates. Peters and Philpot4 concluded from studies of crystalline preparations made at Oxford that the maximum characteristic of B1 is more probably at 2450 A.
