Prince Xavier is next to the Prince Royal, and has always been the Queen’s favourite, and she tried every way to persuade the Prince Electoral to go into orders that this Prince might succeed his father. His person is good, and I believe his natural parts are so too, but his education has been very unfortunate. He is sixteen years of age, and has hitherto been taught nothing but bodily exercises; and they do not seem to think in this country that a Prince wants any accomplishments who can dance, fence, ride at the ring, and shoot at the mark. This Prince has not yet learned common good manners, and is almost a stranger to common decency. The French Ambassador and I dined with him the other day, and the whole time we were at table he talked to the Pages behind him, and what he said to them was in German. Monsieur des Issarts was quite out of humour at the treatment he met with: I was only sorry for the Prince. But to end his character, those who are best acquainted with him tell me he is very proud and very malicious. ’Tis publicly known that he hates his elder brother; but his pride is much abated, and his spirits much sunk since the Electoral Prince’s marriage, which was a thing that he had been taught to believe never would happen. Still he flatters himself with the hope that if the King his father should die, he should succeed him in the Throne of Poland. Prince Charles is next; he is a fine youth about thirteen; his person is good, and he has great quickness of parts; but as he labours under the misfortune of having the same wretched education as his brothers have had, ’tis impossible to say how he will turn out; and here I must observe, that the scarcity of men of ability is so great in this country, that out of four governors employed in the education of these Princes, there is not one who is a Saxon. The two other Princes, Albert and Clement, are both so young, that I can say nothing about them.
