from Dublin, and worthy the notice of the tourist for its round tower, 84 feet in height, close to a church of modern erection, but surrounded by ancient ruins supposed to belong to a Danish palace, and an archiepiscopal see. Tallagh, 5 m., a straggling village. See venerable archiepiscopal palace, now deserted: also fine prospect from summit of the hill; and Timoon Castle in ruins. In the NORTH WEST, see Castleknock, a small pleasant village, 4 m. W., and its old Castle in ruins, built in the reign of Hen. II. and commanding a fine view. Near it is the venerable ruin of Drymnagh Castle, in a most romantic spot; also Dunsink, where stands the Observatory. Glasmenogue, in the vicinity, is a station for the passage-boats on the Royal Canal; an excursion on which cannot fail to amuse the tourist. GLASNEVIN is 2 m.

Its hot-houses possess an immense variety of curious exotics, and the whole extent is little short of twenty acres. Luttrell's Town, 3 m. from Dublin, through the Phœnix Park: a fine seat, with handsome lawn bounded by rich woods, through which are many ridings 4 m. in extent, leading through a romantic glen by the side of a stream falling over a rocky bed, amidst the dark foliage of steep slopes through which the Liffey is heard or seen at intervals; the whole is of great extent, and forms a most picturesque retirement. LEIXLIP is a pleasant town 8 m. W. of Dublin, on the very verge of the county, with a good Inn.--See Carton (Kildare), the elegant seat of the Duke of Leinster; also the Castle, with fine grounds and romantic scenery: the ruins of Confy Castle; and beautiful vale watered by the Liffey.

Lucan, 6 m., is a delightful village, with sulphureous chalybeate in a grove on the banks of the river. See the house and picturesque ground; also Iron-works, Calico-mills, and Limestone quarries.
