Palmerston's conduct was, unquestionably, ill-advised in thus attempting to apply to Spain, in the middle of the nineteenth century, the stipulations of diplomatic instruments framed when the conditions of Europe were very different. But, if his objections to the Infanta's marriage, founded upon the Treaty of Utrecht, were unsuccessful, he was afforded the satisfaction of completely refuting the pleas set up by M. Guizot in justification of his actions. The argument which forms the main contention of his despatches, both of October 31, 1846 and of January 8, 1847, is unanswerable. The _Memorandum of February 27, 1846_, to which the French government attached so much importance was, he pointed out, unofficial and verbal. No record of it was to be found at the Foreign Office. M. de Jarnac had never mentioned it to him, "until after the event had happened for which it was now quoted as a justification." But, "even admitting for the sake of argument that Her Majesty's present government were to be held bound by it, how could it justify a departure from the engagement of Eu? The imminent danger, specified in that _memorandum_, was the likelihood that either the Queen or the Infanta should be about immediately to marry a foreign Prince, not being a descendant of Philip V. But if that likelihood had ever existed, it had at all events ceased to exist, when M. Bresson demanded the hand of the Infanta for the Duc de Montpensier. Not only had it then ceased to exist, but with respect to the Queen, whose marriage was then the immediate and only subject of discussion, it had been succeeded by an impossibility; because when Count Bresson demanded the hand of the Infanta the marriage of the Queen to the Infant Don Francisco had actually been resolved upon and settled."[864]
