At Delmonico's last night the Patriarchs gave another of those brilliant private balls which have formed such a marked feature of the fashionable season. The society, now in its seventh year, was originally founded for the purpose of giving social entertainments of undoubted tone and exclusiveness, and embraces in its membership some 45 or 50 gentlemen from the higher social circles in the City. Their entertainments have, during the last seven years, become as celebrated for elegance of detail as the Philadelphia assemblies. The floral decorations are always fine. They were peculiarly so last evening, probably following the universal taste for floral display that has been one of the features of the season.

A distinctive trait of the entertainment last night was the mellowness of the illumination, which was relieved of the unpleasant glare so fatiguing to the eye at many a ball, and so impairing to the effect of toilets. This was produced by the use of imported porcelain globes, tinted with pink. The special feature of the ball was the opening at 10:30 with an old-fashioned quadrille, one that has not been danced in this City since the famous occasion when the Prince of Wales opened an entertainment with Mrs. Morgan, the wife of the ex-Governor. Only the original members of the society participated. The couples were arranged as follows: Mr. Ward McAllister and Mrs. William Astor, and Mr. August Belmont and Mrs. F.G.D'Hauteville, Col. De Lancey Kane and Mrs. Philip Schuyler, and Mr. Meredith Howland and Mrs. George Griswold Gray, Mr. James P. Kernochan and Mrs. Maturin Livingston, and Mrs. Buchanan and Mrs. Blight of Philadelphia. Mr. Paul Forbes and Mrs. William Bliss and Mr. William Cruger Pell, Commodore and mrs. Baldwin, and Mrs. Rutherford, Mr. Townsend Burden and Mrs. Buchanan Winthrop and Mr. N.M. Beckwith and Mrs. James P. Kernochan. Mr. W.W. Phipps and Mrs. R. Irving and Mr. F.G. d'Hauteville and Mrs. Delancey Kane.

At 12:30 o'clock the supper was served in the restaurant on the first floor, fronting on Fifth-avenue, and, at the same time, the large supper-room above was thrown open. Last night was the first occasion upon which both have been necessary to the accommodation of the guests. At 1:30 dancing was resumed, Col. De Lancy Kane leading in the cotillion with Mrs. F.G. D'Hauteville, and from that hour until 3 o'clock, when the guests began to order their carriages the ball room presented a scene of surpassing brilliancy.
