Die Theorie liefert ¢aber² zwanglos die bisher bekannten Gesetze des Gravitati- onsfeldes und des elektromagnetischen Feldes sowie einen Wesens- Zusammenhang beider Feldarten aber ¢nicht² sie bringt uns über die Struktur der Elektronen keine Aufklärung. AD. [1 029]. The manuscript consists of five pages. The first two pages were written on the back of a fragment of an unidentified typescript. The third, fourth, and fifth pages were written on the back of the beginning of a typescript of Hans Reichenbach’s contribution to the meeting of German phys- icists in Jena, 18–24 September 1921 (Reichenbach 1921). Cropped. See Einstein 1923s (Doc. 123) for an English translation. [1]Dated by the fact that the translated version was published in Nature in its issue of 22 September 1923. [2]The editor of Nature had requested the article in Abs. 16. [3]Eddington 1921, 1923. The following presentation of the theory is based on Einstein 1923e (Vol. 13, Doc. 425) and Einstein 1923h, 1923n, 1925a (Docs. 13, 52, 282, respectively).

The latter was Professor of Astronomy and Experimental Philosophy at the University of Cambridge and director of its Obser- vatory. [5]At this point in the original text, Einstein indicates a note he has appended at the foot of the page: “Summationszeichen werden in […].” In the published version (see the following document), the footnote reads: “In accordance with custom, the signs of summation are omitted.” [6]At this point in the original text, Einstein indicates a note he has appended at the foot of the page: “Herr Droste in Leiden ist unabhängig von mir auf dieselbe Idee gekommen.” Droste’s contribution is also acknowledged in a footnote added in proof to Einstein 1923n (Doc. 52).
