The second Patriarch's ball of this season was given last evening at Delmonico's, and it was a remarkably brilliant social event. The ball-room, parlors, and halls were elaborately decorated with laurel, magnolia, ivy, and white camellias. The mirrors were framed in white camellias. Against the walls baskets of flowers were hung on a background of ivy, and bouquets were suspended from the chandeliers. The ball began about 11 o'clock, and waltzes and quadrilles occupied the interval until supper, which was served at 12:30 in the restaurant down stairs. The upper supper-room was open from the beginning to the end of the ball, and there could be had such light refreshments as ices, champagne, bouillon, &c. The cotillion began at 1:30 o'clock and continued until 3. It embraced about 80 couples, and was led by Mr. William Parsons, who danced with Mrs. Robert Goelet.
