Berlin: Verlag der Akademie der Wissenschaften, 1928.

First Thus. Soft cover. Einstein, Albert (1879-1955). Riemann-Geometrie mit Aufrechterhaltung des Begriffes des Fernparallelismus. Berlin: Verlag der Akademie der Wissenschaften, 1928. 4to., 7pp. Orange wrappers. A very fine copy of this uncommon offprint. First Edition; the rare off-print from the "Sitzungsberichten". 'The general relativity theory splendidly justified his work. In this mathematical apparatus developed from Riemann's address, Einstein found the frame to fit his physicals ideas, his cosmology, and cosmogeny; and the spirit of Riemann's address, was just what physics needed: the metric structure determined by physical data'. -cf. DSB XI, 447-456 (Riemann)Weil No.161; Schilpp-Shields No. 217; Alicke No. 139. The early Offprints from "Sitzungsberichten." are called "Sonderabdruck" up to Weil No.165 (including this). From Weil 166 they are called "Sonderausgabe.". - Before 161 (up to 160) the Offprints do not have separate title and pagination (the pagination follows the numbering in the periodical). From 166 the Offprint has both separate printed title and pagination. - ( So Weil Nos 161-165 is still "Abdruck", but with separate title and pagination)."
