This was determined according to ASTM methods, described in Paper and Paperboard: Characteristics, Nomenclature, and the Significance of Tests, 1963, as follows: The paper strip was dampened, allowed to dry, and then observed under low magnification. The wire pattern became evident.

K�hler Illumination is used for high resolution, and is described in McCrone, W., McCrone, L., Delly, J., Polarized Light Microscopy, Ann Arbor Science, Michigan, 1979, pp. 30, 32. The intensity on the rheostat was adjusted such that the camera's meter was balanced when the shutter speed was 1/4 second.

The film for both sets of slides was Kodak Ektachrome Tungsten, ASA 160.
