THE TRANSPARENCY OF LIVE AND DEAD ANIMAL TISSUE TO ULTRA-VIOLET LIGHT

Abstract

An extremely simple and conclusive method shows that little difference of transmission exists between live and dead tissue, for the next few hrs. after death, if kept wet in Ringer solution and well stretched. Therefore with proper precautions dead tissue can be used for the study of light transmission through animal skin. The pronounced difference of transmission through dried and wet skin permitted estimation of the relative importance of true absorption and scattering. The true absorption coefficient changed strongly with the wave length; the scattering coefficient was nearly constant.
