Progressive Lightning

Abstract

IN NATURE of Nov. 20, 1926, p. 749, I showed how, by the use of a pair of photographic lenses carried on a rapidly revolving disc, information should be obtained as to the time any part of a flash of lightning lasts, how long it takes to get from any one part to any other part, where it begins and where it finishes, and how, if at all, succeeding flashes in a multiple flash differ in these respects from the pioneer flash which, so to speak, blazes the trail and has more to do to find a way which the others have merely to follow.
