Copy letter from Herbert Rix, to Professor Victor Horsley, Fellow of the Royal Society 'Dear Prof. Horsley, Harrisons say that they can let us have a complete proof of your lecture by the 30th. You could have some sheets in advance if you desire. As to the clichés, I can order them for you at once if you will let me know which two woodcuts they are that you want reproduced. Yours truly H Rix Asst. Sec. RS [Assistant Secretary, Royal Society]'. 25 June 1891
