Copy letter from Herbert Rix, to Professor Walter Frank Raphael Weldon, Fellow of the Royal Society 'Soirée Dear Professor Weldon, We are expecting to hear from you soon whether Monsieur Boutau will show his deep-sea photographs. Mr E. J. Browne of University College Laboratory has not answered respecting the medusae suggested as an exhibit. Perhaps you would remind him as we want to have particulars very soon. Yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 16 April 1894
