On each side of this hall are picture galleries, which are so arranged in size and form as to admit of classification of pictures, and which can be divided into suits where separate exhibitions may be held at the same time. The art collections of the gallery are considered the most valuable in America. They comprise the masterpieces of Stuart, Sully, Allston, West, and others of our early artists, the Gilpin gallery, fine marbles, and facsimiles of famous statues, as well as a magnificent gallery from the antique.[17]
