The works of the London clock are of iron, cast with the teeth; those in this are of the best composition metal, cut by machinery in the most scientific form. The powerful first motion wheels of the former are 27 inches in diameter-of the latter 28 inches. Tho, pen�ulum of the former is 15 feet in length-cf the latter. 2\ feet. The escapement of tbis clock is of the form known as the pin-wheel, one of the dead beat styles. The pallets are mounted with agate. This is the same general style with which this firm have been so successful in tbeir clocks for depots, and other situation3 rcq'liring very accurate indications of time. Several new features, however, have been introduced, specially adapting the mechanism to its in creased size; and much admiration is elicited by the Ekill and exquisite beauty of the whol e. All the work is mounted and finished in the highest style known.
