Her Majesty's Mails

Letters for passengers on board the Mediterranean packets about to sail from Southampton for India, China, Australia, &c. and the Canadian mail packets touching at Londonderry, may, under similar conditions, be posted up to the same time as registered letters for India and Canada. The letters should be addressed thus: "Mr. ----, on board the mail packet at Queenstown, Londonderry, or Southampton (as the case may be), care of the officer in charge of the mails." Letters directed to the care of the packet agent at Suez, and despatched by the Indian mails viâ Marseilles, which always leaves after the mails viâ Southampton, will most probably there reach passengers for India, &c. who may have previously sailed in the Southampton packets.
