Undeliverable London Penny-Post letters to be returned free
IT being apprehended that all Miscarriages of Penny-Post Letters are imputed to Negligence in the Office, whereas Directions frequently cannot be made out, especially to Persons in Lodgings for want of their Landlord's Name, or Sign, as also many Letters are refused on account of paying the Second Penny due on Delivery according to Act of Parliament. Now as a Proof of the Attention paid to the Correspondence of the Public, all Letters returned by the Letter Carriers after Three Days Inquiry will be sent back, as the inclosed is to the Writer, gratis, if His or Her Place of Residence can be discover'd, to the end that in case the Reason alledged on the Reverse of the Cover does not appear satisfactory, the Writer may have an Opportunity by complaining to this Office of discovering where the Fault lays.
