Copy letter from Herbert Rix, to Henry Wilde, Fellow of the Royal Society 'Dear Sir, We will do our best to arrange for the exhibit of the Magnetarium and of the new instrument; but as the former, at any rate, must be shown, I suppose, in the meeting room, it can only be shown in the intervals of the lantern exhibits. Perhaps, however, it would do in some other part of the building, in which case there will be no difficulty. You will receive a schedule as to the particulars of the instruments shortly, which we will trouble you to fill up and return. I am, yours truly, H Rix Asst. Sec. RS. [Assistant Secretary, Royal Society]'. 9 April 1894
