Such considerations must ever be borne in mind by the Minister for Foreign Affairs. But least of all men should he be influenced by regard for rank, social station, or political opinion in his choice of attachés and other persons in any rank in diplomacy. Especially where he is about to despatch an embassy to a state under popular government, he will remember that the ambassador will require many agents to keep him in touch with all the different parties. It is therefore to be observed that those embassies which are sent to popularly governed states must be chosen with greater care and equipped with a more varied staff than those despatched to a foreign court where the government rests entirely in the hands of the King. [Sidenote: _The Diplomatic Hierarchy: Ambassadors._] Before discussing in detail the duties of negotiators, I shall describe the different titles which they receive, and the functions and privileges attached to their office. Negotiators are of two kinds: of the first and second order. Those of the first order are Ambassadors Extraordinary and Ambassadors Ordinary. Those of the second are Envoys Extraordinary and Residents. Ambassadors extraordinary receive certain honours and distinctions not accorded to ambassadors ordinary. The ambassadors extraordinary of crowned heads are lodged and entertained in France for three days, by order of the King, in residences set aside for them, while ambassadors ordinary are not so entertained by the King, though in other respects they enjoy the same honour and privileges as the former. These privileges consist in the enjoyment under international law of immunity and security, in the right to remain covered before the King in public audiences because they represent their masters, in the privilege of being borne in the King’s coach, and of driving their own coaches into the inner court of the Louvre.

In France the ambassadors of the Dukes of Savoy enjoyed the same honours as those of the crowned heads of Europe. Abroad the King’s ambassadors enjoy different ceremonial rights according to the customs established in different courts. The French ambassador in Rome, for instance, gives his hand to the ambassadors of certain crowned heads and of Venice, but there are certain ambassadors of other sovereigns who do not receive this courtesy, though at other courts it is accorded to them by the French ambassador. The French ambassador takes first rank in all ceremonies in Rome after the ambassador of the Emperor. These two ambassadors receive the same salary, and are treated otherwise on a footing of equality. There are several courts at which the French ambassadors give their hand to certain princes of equality in the country: in Spain, for instance, we find the Grandees; in London, the
