[Footnote 5: the first three letters of the word cannot be correctly read on the original book] The rolling of a coach into the court was a signal for us to be at our posts, and we abandoned the bureau so lately occupied by the great father of diplomacy, for the drawing-room. I have already told you that this dinner was in honour of Mr. Canning, and, although diplomatic in one sense, it was not so strictly confined to the corps as to prevent a selection. This selection, in honour of the principal guest, had been made from the representatives of the great powers, Spain being the least important nation represented on the occasion, the republic of Switzerland excepted. I do not know whether the presence of the Swiss charge-d'affaires was so intended or not, but it struck me as pointed and in good taste, for all the other foreign agents were ambassadors, with the exception of the Prussian, who was an Envoy Extraordinary. Diplomacy has its honorary gradations as well as a military corps; and, as you can know but little of such matters, I will explain them _en passant_. First in rank comes the Ambassador. This functionary is supposed to represent the personal dignity of the state that sends him. If a king, there is a room in his house that has a throne, and it is usual to see the chair reversed, in respect for its sanctity; and it appears to be etiquette to suspend the portrait of the sovereign beneath the canopy. The Envoy Extraordinary comes next, and then the Minister Plenipotentiary. Ordinarily, these two functions are united in the same individual. Such is the rank of Mr. Brown. The Minister Resident is a lower grade, and the Charge-d'affaires the lowest of all. _Inter se_, these personages take rank according to this scale. Previously to the peace of 1814, the representative of one monarch laid claim to precede the representative of another, always admitting, however, of the validity of the foregoing rule. This pretension gave rise to a good deal of heartburning and contention. Nothing can, in itself, be of greater indifference whether A. or B. walk into the reception-room or to the dinner-table first; but when the idea of general superiority is associated with the act, the aspect of the thing is entirely changed. Under the old system, the ambassador of the Emperor, claimed precedence over all other ambassadors, and, I believe, the representatives of the kings of France had high pretensions also. Now there are great mutations in states. Spain, once the most important kingdom of Europe, has much less influence to-day than Prussia, a power of yesterday. Then the minister of the most insignificant prince claimed precedency over the representative of the most potent republic. This might have passed while republics were insignificant and dependent; but no one can believe that a minister of America, for instance, representing a state of fifty millions, as will be the case before long, would submit to such an
