    "abstract": "In view of the enormous increase in the production of motion pictures during the past few years and of the great financial investments represented in the negatives which it is desirable to preserve in the best physical condition for future use, it is necessary that the utmost care be exercised in processing, printing, and storage of such negatives. The best methods known for the preservation of motion picture negatives are discussed.",
