“ The despatches which pass between the foreign office and its representatives abroad, and which cannot be entrusted to the postal service or the telegraph, are carried by special couriers, styled, in the British service, King’s Messengers. “Courier,” more particularly, is applied to a travelling attendant, whose duties are to arrange for the carrying of the luggage, obtaining of passports, settling of hotel accommodation, and generally to look to the comfort and facility of travel. ”
