Copy letter from Herbert Rix, to [John William Strutt] Lord Rayleigh, [Royal Society] 'My Lord, It will be necessary for you to enter Mr Willard Gibb's name & qualification in the Foreign Member Book before the next Council meets if he is to be ballotted for. This ought properly to have been done at yesterday's Council, & the Book was on the table for the purpose. Yours truly H Rix'. 29 October 1891
