Requests reprint of AE’s latest work. ALS. [24 210]. 833. To Paul Hausmeister [Berlin,] 16 January 1929 In reply to Abs. 828, explains that Hausmeister is incorrect: the average velocity of a molecule depends only on temperature, and not on pressure. In any case, it does not in- crease with pressure. Believes incorrect considerations regarding reversibility were used when analyzing the energy loss in water hydrolysis under pressure. TLC.

To Theodor Wolff [Berlin,] 16 January 1929 Wishes to help promote the German edition of Shaw 1928, and encloses a note to this effect, hoping something could be printed in Berliner Tageblatt. TLC.

Must Germany pay reparations because it has lost the war, or are other political actions possible? How much should Germany pay, taking into account previous payments?

To Arthur Korn Berlin, 19 January 1929 In reply to a nonextant letter, since he is suffering quite seriously from a heart ailment, will be unable to travel to Geneva. H.

Müller must be correct in that the cover of the violin is the acoustically active part. Proposes the use of a sound post made of a heavy metal to test whether the sound disappears. It should not. Explains how the string produces sound. The main static problem to solve is a possible relieving of the strain in the sound-transmitting cover. TLC. [47 680].
