Copy letter from Herbert Rix, to Professor Caruel, Museo Botanico, Florence [Italy] 'We formerly sent the Transactions ['Transactions of the Royal Society'] to the Reale Museo di Fisica, and we think that the volume for 1889, which you say you did not receive, must have gone there. It is certain that it was sent off from here on August 21, 1890. Yours truly Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. [October 1891]
