Abstract
Max Møller and Prescott1 have directed attention to a series of previously unrecorded absorption bands of reduced solutions of cytochrome c from heart muscle (Sigma Chemical Co., U.S.A.; and Boehringer und Sohne, Mannheim). In the course of an investigation of the cytochrome occurring in fungi, we have examined several commercial preparations of cytochrome c for purposes of comparison (Sigma Chemical Co.; L. Light and Co.; etc.); the results obtained with Sigma and Light's materials are recorded in Table 1.
