Abstract
HAVING now been engaged for a number of years in measuring the velocity of light by means of the rotating mirror, I have succeeded in rearranging the apparatus in such a manner as, by means simply of two mirrors, one fixed, the other movable, placed at a distance of a few metres from each other, to obtain, even with a very moderate velocity of rotation, a deviation of the image of a fixed object as large as may be desired in theory and limited in practice only by the intensity of the light and the perfection of the optical apparatus.
