B, W and G stand for the brown, the intermediate white and the green layers, respectively. diffuse transmitted light, and the fraction varies, depending on the optical geometry of the instrument and the angular distribution of the diffuse transmitted light (Shibata, 1959). When such a detector is used in making measurements on translucent samples, quasi-attenuance (Shibata, 1959) is measured rather than absorbance or semi-integral attenuance (Shibata, 1959). The light transmitted through a heterogeneous translucent sample is generally composed of different kinds of light with different angular distributions of intensity. A typical example is the light transmitted through a cell suspension which is composed of completely parallel light transmitted through the suspending medium and diffuse light trans- mitted through the cells in suspension. The measurement at a distance from a heterogeneous sample captures different fractions of these different light fluxes, so that the spectrum thus observed in terms of quasi-attenuance is greatly distorted as demonstrated previously (Shibata, Benson and Calvin, 1954, Shibata, 1957, and Shibata, 1958). d) The photocathode of the end-on photomultiplier, Shimadzu R-236, developed for this spectrophotometer is more red-sensitive than ordinary photocathodes. A high resolution was thereby obtained in the spectral region of.
