なにより、ここへ導かれる契機となって提供された、今は亡きAlbert Abraham Michelson博士と、その、Henry G.Gale氏、 Fred Pearson氏ほか協力者たちが残された貴重な功績なしには到達し得なかったものであり、その尊敬の念は筆舌に尽くし得ません。

その概要は左記の通り、真空化された12インチパイプを水平に300m×600mの長方形に組んだもの。
入射した光をスプリッターで別け、図のように互いに逆周回させると、地球自転による相対速度のため0.25波長のずれを検出した。

Above all, we could not have reached this point without the precious achievements which have led us and provided for us plentifully, from the late Dr. Albert Abraham Michelson and his cooperators Mr. Henry G.Gale, Mr. Fred Pearson, and others. I can hardly describe the respect by means of any words.
Appendix: *Michelson-Gale-Pearson'sexperiment
(1925, in the Illinois Prairie west of Chicago, U.S. A)
Its outline is shown as in Fig.4. The vacuated 12-inch pipe is horizontally constructed by the rectangle (300 m×600 m).
The introduced light was divided into two rays, which were reflected and refracted, respectively, by the splitter. Then, owing to the relative-velocity of light produced by the Earth’s rotation, the gap of 0.25 waves was detected between the two rays of light.
