Copy letter from Herbert Rix, to Professor [John] Prestwich There seems to be a little uncertainty about the title of Prestwich's paper as it stands in one form in the Register and in a different form in the abstract. The titles must be exactly alike and they wish to settle the form as the 'Proceedings [of the Royal Society]' sheet is waiting for publication until this is settled. Encloses a copy of the title for approval or amendment [not attached]. 18 May 1893
