In a study by F. Calogero [1] entitled "Cosmic origin of quantization" an expression was derived for the variability of h with time, and its consequences if any, of such an idea in cosmology were examined. In this paper we will offer a different derivation of the Calogero conjecture based on a postulate concerning a variable speed of light, [2] in conjuction with Weinberg's relationship for the mass of an elementary particle.
