Copy letter from Herbert Rix, to C Hobson, York House, Twickenham, Middlesex 'Sir, In answer to the question which you ask on behalf of Sir M E [Mountstuart Elphinstone] Grant Duff, every Fellow of the Society has a right to introduce two strangers to the meetings. We have no tickets of admission, but the visitors must bring with them either a note from the Fellow who introduced them or the Fellow's visiting card. I inclose herewith a card which will show the dates of the forthcoming meetings. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 29 January 1895
