Bleed-outs on the outside edge of the pages were eliminated in order not to conflict with the tabs.

The effect of shading on the borders was secured on pages 34, 35, 42, 43, 92, and 93 and several others, by using Transograph Shading Film DT-60, manufactured by Transograph Corporation, 30 West 15th Street, New York City.
