But while Comstock himself tried to get by not easy observations a direct check of the predicted deformations, De Sitter (4) published a brief analysis on the phenomena of the "doubles" which seemed and still seems clear and decisive against the hypothesis (ballistics) of Ritz (5), which admitted the composition of the speed of light with that of the source, and therefore indirectly in favor of the postulate on "constancy of speed of light" which is the very basis of Einstein's theory.
