2-page TLC to Vieweg publishing house. Proposes to
request 8% for himself, 4% for Vieweg from the French
publisher (see entry of 26 May), and to ask the publisher
for payment of an aggregate sum of not less than 500 francs
to Jeanne Rouvière, a prospective translator (see 8 March
1920 in Vol. 9, Calendar). As to the Russian translation, it
will be sold mostly to well-to-do Russians living outside
Russia. Proposes 5% for himself, 3% to Vieweg, and 3% to
Itelson, who lives in straitened circumstances. Hopes to
have time to send the addenda to the 10th edition of Einstein
1917a. His request for 20% is not high because percentage-
wise he had been undercompensated for the last editions.
