First edition, offprint issue, of the third of Einstein and Mayer's four classic papers on semi-vectors, in which they aimed to incorporate the Dirac equation into the general theory of relativity. "By introducing semi-vectors, Einstein wanted to arrive at a mathematically simpler and more general formulation of spinors. The semi-vector generalization of the Dirac equation was thought to give a unified description of charged elementary particles, in particular of the electron and proton" (Van Dongen, pp. 103-5). Boni 223; Weil 192. Jeroen van Dongen, Einstein's Unification, 2010. Large octavo, pp. 4. Original cream wrappers, front wrapper printed in black, wire-stitched as issued. Extremities gently creased, short closed tears at spine ends, occasional light foxing: a very good copy.
