Copy letter from Herbert Rix, to Dr Ramsey HeatleyTraquair, Fellow of the Royal Society 'Private [underlined] My dear Sir, I venture to exceed my duties by reminding you that on the last day of this month you will cease to be F.R.S. [Fellow of the Royal Society] through non payment of annual contribution, if it does not arrive before. It is such a pity for anyone to undergo this vexation from a mere slip of memory that I have usually in such cases sent a little private reminder like the present. I am, yours very truly Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 5 October 1891
