One of the most interesting parts of the New Opera is the _foyer_, corresponding more or less to the refreshment room of our operatic theatres, but quite incomparable in the way of elegance and splendour. In the accompanying illustration the artist has made a point of introducing, amid well-dressed persons in evening clothes, an English lady in a morning gown and a sea-side hat, accompanied by two of her countrymen in shooting coats and pot hats. It is, indeed, a standing grievance with the Parisians that, whereas at our opera house no one is admitted to the boxes or stalls unless in evening dress, we ourselves, when we visit the Paris Opera, think any description of garment good enough to wear. One of the characteristic sights of Paris has, for nearly two centuries past, been the Masked Ball of the Opera, which, though it has doubtless lost much of its gaiety since the days when it inspired Gavarni with so many subjects for his witty pencil, is still worth seeing, simply as a picturesque display. No one any longer dances there unless paid to do so. It was, in fact, the introduction of hired dancers when the public were just beginning to show a disinclination to take an active part in the revels that put an end to spontaneous dancing altogether. The antics of some of the hired dancers may interest for a time; and the music of the large orchestra, conducted successively by Musard, Tolbecque, Strauss, Métra, and Arban, has always merited a hearing. Throughout the Carnival--that is to say, from Christmas until Lent--a masked and fancy dress ball (the wearing both of masks and fancy dress being optional) is given every week at the Opera, where the great ball of the year takes place on the night of Shrove Tuesday, the day preceding Lent. One other ball of the same kind is given in the middle of Lent--_la Mi-carême_ as it is called--and thenceforward there is no dancing at the Opera until Christmas has once more come and gone.
