Just as we are putting our last form to press the Brooklyn Society is in the midst of its fall exhibition. Their new room at Montague Hall is not. in some respects, as good as their old one at the Athenaeum, but it is somewhat larger: the ceiling is too low, and the room too narrow. We hope next year to see them at the Academy of Music. The President has been unwearied in his exertions, and is rewarded by a remarkably fine exhibition. We have only time at present to notice some of the leading features The collection of fruit was a very choice one. The samples of Apples and Pears from Messrs. Ell-wsnger &, Barry, Briggs, Sprunt, Gordon, Ryan & Co., Marx, Quin, Field, and others, were exceedingly fine. Foreign Grapes were shown in quantity, bunches and berries both being large and fine: this part of the exhibition, indeed, was an advance upon any thing the Society lias yet had. The season was too early to see a fine show of native grapes, the Delaware and Hartford being almost the only two kinds in condition to eat, except some grown under glass, which, strangely enough, were put in competition with those grown in the open air. There were two large fruit baskets admirably arranged; they would have been still better had they been smaller.

Among the exhibiters of Grapes were Messrs. Cowan, Mullen, Egan, Schmeig, Fuller, Merrit.

The display of Pot Plants was very choice. The leading feature in this department consisted of variegated leaved plants, such as Caladiums, Begonias, Crotons, Marantas, Ananassas, etc. Another striking feature was a large number of Bilbergias in bloom, distributed through the room; and still another, very large and fine specimen of Ferns and Lycopodiums. Here and there in collections might be seen a new or rare plant, which we can now only allude to; but we must not forget one very attractive object, a couple of leaves and a flower of the grand Victoria regia, presented by James Dundas, Esq., of Philadelphia.

The cut flowers were not as numerous as on some former occasions, but they were quite unexceptionable, especially the miscellaneous show of Mr. Weir and Mr. Humphrey, the Roses of Messrs. Dailledouze & Zeller and M. Donadi, the fine Verbenas of Peter Henderson, the splendid specimen Dahlias of Mr. Richardson and the collection of Mr. Veitch, as well as those of Messrs. Brenner, Poynter, and others. The display of Bouquets, Baskets, etc., was very pretty and attractive; we think the effect would have been enhanced by placing the circular table under the dome. But our printer is waiting, and we can only say in conclusion that the exhibition was a highly creditable and successful one, and will be remembered with pride. There were a great number of choice and beautiful objects in the room, which were highly appreciated; but we hope the members will not impeach our taste when we say that the Presiident of the Societv presented one of the loveliest of them all.

In conclusion, we give a condensed list of the prizes.
