We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

10 FILM (Daring Inspection) separate the layers without excessive damage, provided that extreme care is used in separating the surfaces. To dry the film spread it so that it cannot touch anything dirty and so that its surfaces do not touch each other. Avoid dust and abrasives touching the film until it is thoroughly dried. Warning: Never roll film when it is damp or water-spotted, or else the emulsion and the pictures on the surface will be ruined. 3. Film Adheres Throughout Its Entire Length (a) — In all probability the film is kept too moist. If it is a new print and can, with care, be separated without destruction, stretch it in a dry, dustless place and let it dry up a little more. If old film is so moist that it adheres, it probably cannot be separated without causing damage. Try very carefully to separate it and if it begins to show damage, substitute another subject or get a substitute print from the exchange. (b) — The reel may have been spattered or may have been dropped into water. If of recent incidence and it can be caught in time, it may be separated and dried in a dustless place. Warning (new film) : When receiving new film handle it carefully. The emulsion of new film is especially soft and is subject to damages and scratches which cause "rain" and other defects.
