Item 11.2 - H. R. Hertz: Über die Ausbreitungsgeschwindigkeit der Elektrodynamischen Wirkungen

1 vol., c 338 x 224 x 6 mm. 20 pp, (with 3 flyleaves at beginning and end, 1 original and 2 from binding). 2 ff. tipped in between pp. 6-7, 1 f. tipped in between pp. 10-11, 1 f. pasted over top of p. 17.

Gift from Elisabeth Hertz, Hertz's widow, in Dec. 1936. Presumably bound subsequently: stamp of 'Cox & Allen, Camb.' on inside front cover.

In Hertz's own hand. 'III' written in blue crayon on front original flyleaf. Hertz's address given in the margin of the first page of the paper: 'Prof. Dr. Hertz, Wadstr. 33, Karlsruhe'. Several annotations and corrections throughout the text of the paper, including to the title. First subtitle crossed out, another below in brackets: 'Aus den Sitzungsberichten der Berliner Akadamie vom 2 Feb. 1888, mit einigen Zusätzen' [as appeared in the paper's second publication in Annalen der Physik und Chemie vol. 34].
