Copy letter from Herbert Rix, to the [Laurence Parsons] Earl of Rosse, [Fellow of the Royal Society] 'My Lord, I am glad that some ^of the^ missing numbers have been found. In case No. 245 of 'Proceedings' ['Proceedings of the Royal Society'] does not come to light, a duplicate will be sent to your Lordship, gratis, as there was in that case some little irregularity in the date of posting. The three missing numbers of 'Transactions' ['Philosophical Transactions of the Royal Society'] can be purchased separately at a small cost. I am, yours obediently, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 1 June 1889
