388 K. FAMULENER AND E. LOESSEL not primarily concerned with these small time intervals. We found that motion picture positive emulsions of various manufacture varied greatly one from another in the rate of latent image regression. MR. HUSE: It is Hollywood practice to make sensitometric exposures some hours ahead of their actual use. For example, the exposures may be made in the morning for use that night. Investigation has shown a more marked regression of the latent image during the first few hours after exposure — beyond which the change is slight and progresses very slowly. MR. CRABTREE : What is the difference between the results obtained with film on a nitrate base and film on an acetate base? Also, what is the effect of high humidity and high temperature in the result ? MR. COOK: We are not prepared to answer Mr. Crabtree's questions at the present time. However, this investigation is being continued and we believe that Mr. Crabtree's queries will be answered when pur later findings are published.
