Copy letter from Herbert Rix, to Professor Silvanus Phillips Thompson, Fellow of the Royal Society 'Dear Sir, I am sorry you did not manage to call yesterday as you promised. It is now too late for us to get current from the Post Office. Does your telegram mean that cells are to be hired from an instrument maker? If so, please hire them and anything else you want and send us the account. No one ^on the premises^ knows anything of electrical science and we must depend entirely upon you to make your own arrangements, as we do not know what to order. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 28 January 1896
