Abstract
IN articles in NATURE and elsewhere, M. E. J. Gheury de Bray has proposed and defended the suggestion that the velocity of light may be a decreasing function of time, varying at present by about 4 km. a second a year. He bases this idea on an examination of the published results of measurements by a number of experimenters over a period of several decades, and concludes that all the results are in good agreement with his hypothesis.
