I shall be much obliged if you will place the inclosed card of invitation before His Royal Highness the Duke of Connaught, and express to him on behalf of myself and the Council the great gratification it would give us and the Fellows of the Society generally if His Royal Highness would honour us with his presence on this occasion.
I am, Sir, your obedient servant,
(Signed) Joseph Lister
Pres. R.S. [President, Royal Society]'.
