Copy letter from Herbert Rix, to Mr A Fowler, Science School, South Kensington 'Dear Mr Fowler, I think it is better that the dias. [diagrams] should come through my hands. They have each to be numbered and named and have to be entered in my register. There is only about two hours lost by sending them to me; I am careful not to delay them. Yours truly, Herbert Rix Asst Sec R.S. [Assistant Secretary, Royal Society]'. 9 March 1888
