a Penny-Post letter
Note by Henry Craik to Letter 4 from Journal To Stella

The penny post, for London and its suburbs, had been established in 1685, as a private undertaking. James II, who, as Duke of York, held the revenues of the Post Office, raised an objection to this as an infringement of the Government monopoly: and the penny post was subsequently carried on as a Government business, although quite separate from the General Post, with which it was not amalgamated until 1854.
