Krakatoa at the Royal Society Soirée

British postcard from Rix asking Symons to present the work they were doing as part of the Krakatoa (Krakatau) committee at the Royal Society Soiree. It reads: "Soiree is on May 11. The sub-committee have instructed me to ask what you can exhibit in connection with the Krakatoa business. H. Rix".
