Copy letter from Herbert Rix, to Dr Heinrich Debus [Fellow of the Royal Society] 'Dear Dr Debus, Fortunately Mr Wheatley called in here this afternoon and I was able to question him about the entry against your name in our "Transactions" book. It appears that the fault has been on our side; and it will not therefore be necessary for you to pay for the 1877 pt. [part] 2 which you have taken. I am yours faithfully, Herbert Rix Asst Sec [Assistant Secretary, Royal Society]'. 10 October 1888
