Abstract
IN vol. lxxviii. of NATURE (May 21, 1908, p. 55) was published a note on “Secondary Waves of Light,” in which I described the diffraction effects produced by an obliquely held rectangular aperture or reflecting surface, and pointed out that the observed distribution of illumination in the pattern was not in accordance with that deduced in the ordinary way. I indicated an explanation of the discrepancy, that it was due to the variation of the obliquity factor of diffraction within the limits of the pattern.
