SIDELIGHTS ON RELATIVITY: Ether and Relativity; II: Geometry and Experience.

London: Methuen & Co., 1922.

First Edition. Hardcover. First Edition. Small 8vo., 56pp. + 8 pages of adverts. A very good copy of this early & now scarce Einstein title. Publisher's blue cloth uncommon variant with lettering stamped in dark blue on the upper cover & spine - the lettering sharp but the spine blue cloth faded as usual. In a very good unrestored original publisher's dustwrapper, black type on a turquoise ground, showing moderate use with narrow chips to the spine crown, heel & tips [one small chip on the back panel]. Contains two small diagrams on pages 49 & 51. In a fine custom slipcase with E=MC2 in relief on the side. Very nice indeed. Contains two lectures: "Ether and the Theory of Relativity" delivered on May 5th, 1920 in the University of Leyden. "Geometry and Experience" an expanded form of an Address given to the Prussian Academy of Sciences in Berlin on January 27th, 1921. Translated by G.B. Jeffery & W. Perrett. One of Einstein's scarcest Methuen titles, certainly as difficult as: RELATIVITY: The Special and General Theory, published in 1920 & THE MEANING OF RELATIVITY, also in 1922.
