Copy letter from Herbert Rix, to R A Lewis, The Grove, Pontypridd 'Dear Sir, There is a fund administered by the Royal Society to aid researches in science, but the practical matter upon which you are engaged is, perhaps, rather one for the Society of Arts (John Street, Adelphi) than for the Royal Society, which deals mainly with pure not applied science. I am, yours faithfully, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 13 April 1896
