The first ball this season of the Family Circle Dancing Class, better known as the F.C.D.C., was given last night at Delmonico's. The F.C.D.C. balls are merely smaller editions of the Patriarch balls, the chief difference being that they begin earlier in the evening, and are limited to a smaller number of guests. they are also arranged so as to break the intervals between the Patriarch balls and therefore form a complement to the latter. The other dates for this season are Jan. 23 and Feb. 20, and what is known as an "extra" will be given on April 11. The decorations of the rooms last night were in most respects the same as on the occasion of the recent Patriarchs' ball. Plants and flowers filled the hallways and recesses, and the small apartment adjoining the south-west corner of the ball-room was fitted up as a conservatory. The windows of the ball-room were hung with rich silver damask curtains, and the floor was covered with white crash. Supper was served up stairs at 12 o'clock in the large room on the Broadway side, which was lighted with pink lights to contrast with the pale straw-colored lights used in the ball-room. The halls and parlors were also illuminated with pink lights.

The ball consisted mainly of the cotillion, which began at 12:30, under the leadership of Mr. J. Ridgeway Moore, and was participated in by about fifty couples. Altogether about 250 persons were present. A notable feature of the evening was the presence of the Nation's French guests, who will sail for Europe today. They are Gen. Boulanger, Col. Bossau, the Comte de Beaumont, the Comte d'Ollone, the Vicomte d'Ollone, the Vicomte de Noailles, the Baron H. d'Aboville, the Baron C. d'Aboville, M.G. de Sahune, Lieut de Sahune, the Comte de Gouvello, M.
