Her Majesty's Mails

(c) No letter, &c. can be forwarded through the post which is more than two feet in length, breadth, or depth, nor any unpaid letter or packet which weighs more than four ounces, unless three-quarters of the postage due on it have been paid. The exceptions to this rule are-- 1st. Packets sent to or received from places abroad. 2d. Packets to or from any of the Government departments or public officers. 3d. Petitions or addresses to the Queen, whether directed to Her Majesty or forwarded to any member of either House of Parliament. 4th. Petitions to either House of Parliament. 5th. Printed parliamentary proceedings. (d) Late letters, &c. are received till within five minutes of the despatch of the mails, except where the Post-Office surveyor may deem a longer interval necessary, and providing that this arrangement does not necessitate any office being open after ten o'clock at night. In each post-office window placards are exhibited showing the time up to which such letters may be posted. No late letters can be forwarded by the mail preparing for despatch unless prepaid in stamps, including the ordinary postage and the late-letter fee. Government letters are an exception to this rule; they may be posted, without extra fee, up to the latest moment. (e) Letters containing sharp instruments, knives, scissors, glass, &c. are not allowed to circulate through the post, to the risk of damaging the general correspondence. Such communications, when posted, are detained and forwarded to the Metropolitan Office, where correspondence is at once opened with the senders.
