**Abstract:**

In this review of the Mount-Wilson experiment, the related mathematical formulas, for calculating the fringe-shift displacement, have been derived, in accordance with the assumption of constant speed of light, and the assumption of ballistic speed of light, respectively. And the numerical results have been obtained, by inserting into the derived formulas the relevant data, gathered by the COBE satellite, regarding Earth's velocity, relative to the CMBR. The computed predictions, at the geographical latitudes ― 7.2 S, 34.2264 N, 41.4993 N, & 82.8 N ― have been compared to the experimental result, in Miller's report. Subsequently, it's concluded that Dayton C. Miller's work, on the determination of the space motion of the earth, is of the same level of accuracy and validity as Ole Rømer's work, on the determination of the speed of light, and bound to be officially recognized as such, at some point in the future.
