Fine content A.L.S. 8vo., 2 pages, blind-stamped stationary, London, January 5th 1910, in French, to Dr. Charles Moureu, in part, explaining that he has had an operation to relieve his painful hemorrhoids and then embarked on a recuperative cruise to South America. Having returned, he is unable to find an invoice from Doctor Moureu, which somehow had become separated from the original envelope. He is sorry for the delay and requests a duplicate. Ramsay then continues with a most incredible scientific revelation: "I have replenished my little tube yesterday of pure Krypton; it does not contain even a trace of Hydrogen..."
