I have spent the whole day in a Paris mob. The arrival of General Romarino and some of his companions from Warsaw, gave the malcontents a plausible opportunity of expressing their dislike to the measures of government; and, under cover of a public welcome to this distinguished Pole, they assembled in immense numbers at the Port St. Denis, and on the Boulevard Montmartre. It was very exciting altogether. The cavalry were out, and patroled the streets in companies, charging upon the crowd wherever there was a stand; the troops of the line marched up and down the Boulevards, continually dividing the masses of people, and forbidding any one to stand still. The shops were all shut, in anticipation of an affray. The students endeavored to cluster, and resisted, as far as they dared, the orders of the soldiery; and from noon till night there was every prospect of a quarrel. The French are a fine people under excitement. Their handsome and ordinarily heartless faces become very expressive under the stronger emotions; and their picturesque dresses and violent gesticulation, set off a popular tumult exceedingly. I have been highly amused all day, and have learned a great deal of what it is very difficult for a foreigner to acquire--the language of French passion. They express themselves very forcibly when angry. The constant irritation kept up by the intrusion of the cavalry upon the sidewalks, and the rough manner of dispersing gentlemen by sabre-blows and kicks with the stirrup, gave me sufficient opportunity of judging. I was astonished, however, that their summary mode of proceeding was borne at all. It is difficult to mix in such a vast body, and not catch its spirit, and I found myself, without knowing why, or rather with a full conviction that the military measures were necessary and right, entering with all my heart into the rebellious movements of the students, and boiling with indignation at every dispersion by force. The students of Paris are probably the worst subjects the king has. They are mostly young men of from twenty to twenty-five, full of bodily vigor and enthusiasm, and excitable to the last degree. Many of them are Germans, and no small proportion Americans. They make a good _amalgam_ for a mob, dress being the last consideration, apparently, with a medical or law student in Paris. I never saw such a collection of atrocious-looking fellows as are to be met at the lectures. The polytechnic scholars, on the other hand, are the finest-looking body of young men I ever saw. Aside from their uniform, which is remarkably neat and beautiful, their figures and faces seem picked for spirit and manliness. They have always a distinguished air in a crowd, and it is easy, after seeing them, to imagine the part they played as leaders in the revolution of the three days.
