While expenditure was a worry for the Treasurer, as Secretary (from 1854), George Gabriel Stokes was preoccupied with the actual content of the "Transactions" and his extensive correspondence with authors over his thirty-one year term. He took up most of his time beyond his duties as Lucasian Professor at Cambridge. Stokes was paramount in establishing a more formalized refereeing process at the Royal Society. It was not until Stokes' Presidency ended in 1890 that his influence over the journal diminished. The introduction of fixed terms for Society officers precluded subsequent editors from taking on Stokes' mantle, and meant that the Society operated its editorial practices more collectively than it had done since the mechanisms for it were established in 1752.
