The Hall was much crowded with the beauty and fashion of the city. Every visitor was highly gratified.

with the display. The object of the greaest attraction, and it assuredly merited all the admiration bestowed upon it, was the leaf of the far-famed Victoria regia, or great water lily, from the hot-house of Caleb Cope, the President of the Society. This leaf was six feet four inches in diameter, or nineteen feet in circumference; of circular form, peltate, emarginate at that portion of the border which was the point of its orignal sagittate shape; a similar notch existed directly opposite, where a suture occurs, which latter is caused by the adhesion of the lobes of its arrow-headed form; the venation was remarkably prominent, and beset with sharp spines, as also was the rope-like petiole; the whole of the under surface was of a beautiful purple tint. The flower bud not having expanded, was not shown; as buds are observed issuing from the plant, it is hoped and confidently expected, that flowers may be seen at the grand autumnal display, commencing on the 17th September. A representation in wax, of the flower, obtained by A. Klmber in Europe, was exhibited. A choice collection of flowering plants, from Robert Buist's, were presented.

Fine baskets of choice cut flowers, from Jno. Ellis, gardener to Caleb Cope, Henry A. Drecr, and Robert Kiivington, were seen.

In fruits the display was really very fine. Of grapes, there were seven contributions, consisting of Black Hamburgh, White Chasselas, Cochin China, White Frontignac, Golden Chasselas, and a collection consisting of many varieties. Nectarines were brought from green-houses, of the Elruge. Vermash, new White, Red Roman, Pitmaston, Orange, and other varieties. Of plums, there were six contributors, and the kinds shown were the Marston, Green Gage, Mammoth, Quetch, Blue and Cleavinger. Highly flavored Cayenne Pine Apples were from the President's houses. Delicious peaches of the Crawford's Early, the Heath, free, and ft seedling variety, were soon. Of pears, there were from one source eight kinds - the Bartlett, Callot Rosat, Washington, Bezi de la Motte, Chaumontelle, Moyamensing, Andrews, and Ah mon Dieu, and the Dewitt, Bartram, Rou'sse-let de Rheims, Seckel, and a seedling, and the Espcrion, St. Ghislain, and three unknown French kinds; the Andrews, Duchess de Berri, the Dearborn's Seedling, the Julienne, the Early Catharine, Seckel and Grate. Of apples, the following varieties - Pearmain, Maiden's Blush, Porter, Hagloe, and Hawthornden. Several Dew varieties of melons were brought forward.

Three fine displays of vegetables were shown.

The committee on fruits submitted a report of fruits examined ad interim - viz: Fine specimens of the Bloodgood, Dearborn's Seedling, Ananas d'Ete, Benoist pears, from Charles Downing, Newburgh, N. Y.; the Gratz, Mather and Ott pears, and Cleavinger plums. The Bloodgood, Dearborn's Seedling, Ananas d'Ete, and Benoist, were of the finest quality; the last were particularly fine. The Gratz was of good quality, and believed to be synonymous with Julienne. The Mather is a large, fair native pear of Delaware county, of great productiveness, but wants flavor. The Ott, as heretofore, sustains its high reputation, excelling in quality all the summer pears. The Cleavinger is a native purple plum, free, of the largest size, and of good flavor. Tho. P.
