Excerpt from Experimental Study of the Relation Between Intermittent and Nonintermittent Sector-Wheel Photographic Exposures All plates were of the commercial 5 by 7 inch size. These were cut in one operation, by a special plate - cutting machine, into seven parts, giving five which are 1-33 - 2 by 5 inches, the two end strips being discarded. The plates after cutting are removed intact - that is, not broken apart - painted on the glass side with a black shellac mixture to prevent halation, and then drieifl in a ventilated closet. After drying they are broken apart and loaded into the plate holders, each having three pockets. In all experiments three kinds of plates were exposed in each holder; for example, A plates in the upper pocket, B plates in the center pocket, and 0 plates in the lower pocket. Since practically every experiment was made with eight holders, this gave 24 test specimens for each designated experiment.
