Proteins in polyacrylamide gels can be rapidly visualized by soaking in trichloroacetic acid or chloroform followed by illumination with UV light. The UV-lightdriven reaction of tryptophan in the presence of trichlorocompounds yields products that emit sufficiently in the visible region to identify

TWO types of visual pigments have been identified in the retinal rods of vertebrates --rhodopsin (A I) and porphyropsin (A2). Wald (1960) suggested a specific pattern of distribution for these pigments in vertebrates on the basis of their habitat salinity. However, data published in recent years on
