The private masks are amusing to those who are intimate with the circle. A stranger, of course, is neither acquainted enough to amuse himself within proper limits, nor incognito enough to play his gallantries at hazard. I never have seen more decidedly _triste_ assemblies than the balls of this kind which I have attended, where the uniform black masks and dominoes gave the party the aspect of a funeral, and the restraint made it quite as melancholy. The public masks are quite another affair. They are given at the principal theatres, and commence at midnight. The pit and stage are thrown into a brilliant hall, with the orchestra in the centre; the music is divine, and the etiquette perfect liberty. There is, of course, a great deal of vulgar company, for every one is admitted who pays the ten francs at the door; but all classes of people mingle in the crowd; and if one is not amused, it is because he will neither listen nor talk. I think it requires one or two masks to get one's eye so much accustomed to the sight, that he is not disgusted with the exteriors of the women. There was something very diabolical to me at first in a dead, black representation of the human face, and the long black domino. Persuading one's self that there is beauty under such an outside, is like getting up a passion for a very ugly woman, for the sake of her mind--difficult, rather. I soon became used to it, however, and amused myself infinitely. One is liable to waste his wit, to be sure; for in a crowd so rarely _bien composée_, as they phrase it, the undistinguishing dress gives every one the opportunity of bewildering you; but the feet and manner of walking, and the tone and mode of expression, are indices sufficiently certain to decide, and give interest to a pursuit; and, with tolerable caution, one is paid for his trouble, in nineteen cases out of twenty.
