Copy letter from Herbert Rix, to Dr S Martin, 10 Mansfield Street, Cavendish Square 'My dear Sir, Prof Schafer [Professor Edward Albert Schafer] tells me that you have only a single ticket, & would like to bring a lady on Wednesday. I have, therefore, entered an instruction on the doorkeeper's list to admit a lady with you, which will be quite sufficient to prevent your being challenged at the door. I am, Dear Sir, faithfully yours Herbert Rix Asst Sec [Assistant Secretary}'. 15 June 1891
