I duly ordered the letter balance of Harrison, but as I order it to be just like mine, I dare say they had to get it from Mordan's. I have had it put down to the R.S. [Royal Society] account, which I suppose is what you intended. Enclosed I send a letter from Professor [Harry Govier] Seeley, which requires your decision.
Asst Sec RS [Assistant Secretary, Royal Society]'.
