under the influence of Adolphe Quetelet, a mathematical professor, who was particularly interested in the application of the laws of probability to political and moral phenomena; this line of inquiry attracted the Prince, and the friendship thus begun continued till the end of his life.  From Brussels he went to the University of Bonn, where he was speedily distinguished both by his intellectual and his social activities; his energies were absorbed in metaphysics, law, political economy, music, fencing, and amateur theatricals.  Thirty years later his fellow—­students recalled with delight the fits of laughter into which they had been sent by Prince Albert’s mimicry.  The verve with which his Serene Highness reproduced the tones and gestures of one of the professors who used to point to a picture of a row of houses in Venice with the remark, “That is the Ponte-Realte,” and of another who fell down in a race and was obliged to look for his spectacles, was especially appreciated.

After a year at Bonn, the time had come for a foreign tour, and Baron Stockmar arrived from England to accompany the Prince on an expedition to Italy.  The Baron had been already, two years previously, consulted by King Leopold as to his views upon the proposed marriage of Albert and Victoria.  His reply had been remarkable.  With a characteristic foresight, a characteristic absence of optimism, a characteristic sense of the moral elements in the situation, Stockmar had pointed out what were, in his opinion, the conditions essential to make the marriage a success.  Albert, he wrote, “was a fine young fellow, well grown for his age, with agreeable and valuable qualities; and it was probable that in a few years he would turn out a strong handsome man, of a kindly, simple, yet dignified demeanour.  Thus, externally, he possesses all that pleases the sex, and at all times and in all countries must please.”  Supposing, therefore, that Victoria herself was in favour of the marriage, the further question arose as to whether Albert’s mental qualities were such as to fit him for the position of husband of the Queen of England.  On this point, continued the Baron, one heard much to his credit; the Prince was said to be discreet and intelligent; but all such judgments were necessarily partial, and the Baron preferred to reserve his opinion until he could come to a trustworthy conclusion from personal observation.  And then he added:  “But all this is not enough.  The young man ought to have not merely great ability, but a right ambition, and great force of will as well.  To pursue for a lifetime a political career so arduous demands more than energy and inclination—­it demands also that earnest frame of mind which is ready of its own accord to sacrifice mere pleasure to real usefulness.  If he is not satisfied hereafter with the consciousness of having achieved one of the most influential positions in Europe, how often will he feel tempted to repent his adventure!  If he does not from the very outset accept it as a vocation of grave responsibility, on the efficient performance of which his honour and happiness depend, there is small likelihood of his succeeding.”
