Copy letter from Robert William Frederick Harrison to Herr Professor G Klebs Kleb's letter will be laid before the Council of the Royal Society at their meeting this week. Harrison has little doubt that the Croonian lecture can be arranged for May 26 and in the meantime Harrions inform Klebs that the Royal Society have a good projection lantern which will be at his disposal. There is not obligation on Klebs to have his lecture in print beforehand; but it is a great convenience to Fellows of the Royal Society to have, in advance, a summary of the principal points. 26 April 1910
