light, after reflexion, is propagated with the velocity c + v, where v is the component of the velocity of the image in the direction of the reflected ray.
To complete these researches I intend, as I have said above, to investigate further with the same interferential arrangements, the velocity of propagation of light from a source set in motion artificially; but of these, and of the general conclusions to be drawn from these investigations, I reserve mention for a future occasion.
