Copy letter from James Hopwood Jeans, Secretary of the Royal Society; to Sir Arthur Schuster, Foreign Secretary of the Royal Society Thanks Sir Arthur Schuster for his suggestion about the Metric Convention. Also notes that [William Henry] Young just called, and claimed that he sent Sir Schuster a letter from Koenigs asking for the subscription to the International Union to be paid to 'some special person'. Asks Sir Schuster to have a look among his things for this letter, and forward it on to the Society in order that they may organise the payment of the subscription. 21 April 1921
