Tungsten light, sound at 12.5 KC/sec. and beta radiation were investigated as a means of measuring degrees of lung destruction in inflated fume-fixed lung sections. A scanning and enumerating device is described which is capable of evaluating the entire section. Absorption of light appeared to give an adequate measure of lung destruction and correlated well with the rank order. Correlation of sound with visual degree of destruction was only fair. Beta radiation with the method used showed no correlation.
