THE OLYMPIC.--This new establishment has taken the town by surprise, in one respect at least. It is the most beautiful theatre on the Atlantic sea-board. Its decorations, scenery, etc., are rich and tasteful; the entire stage is carpeted, the stage-management is well conducted, and both in internals and externals, it reflects credit upon the liberality and taste of the proprietors. We have been unable, as yet, to attend upon any of the performances; but are informed that they have been highly creditable, bringing out Mr. BARRETT, Mrs. MAEDER, (CLARA FISHER.) Mr. FLINN, Mr. GATES, and other Thespians of eminence. We wish the 'Olympic' success, which we doubt not it will command by deserving it. * * * * * DUBUFE'S DON JUAN AND HAIDEE.--The time of this picture is when Lambro, the father of HAIDEE, surprises her with DON JUAN; and the scene is too well known to require description. The painting itself is beyond comparison, in richness, beauty, and effect, the finest effort of art yet exhibited in this country. We shall not attempt a detailed sketch of its numerous points of attraction; but simply enjoin upon all who may read this paragraph, within an hour's walk or ride of the Stuyvesant Institute, to repair thither 'at the meetest vantage of the time,' to become for a season 'dazzled and drunk with beauty.' At the same exhibition-rooms, is another painting by DUBUFE, of 'St. John in the Wilderness.' It is a faultless production. * * * * *
