The external appearance of this chapel is illustrated in Fig. 1157, where the fine angle buttresses of the apse, with their considerable projection and height (owing to the upper story) and their picturesque pinnacles, and the stair turret are fully shown. The buttresses have each an ornamental corbel and canopy for a statue placed on their face, but without any niche. Fig. 1164 shows one of them with its elaborate carved work. The very quaint aspect of the whole building looking from the west is seen in the drawing (see Fig. 1158). The height of the two turrets, as shown on Mr. Mackenzie’s geometrical drawings, is the same, viz., 41 feet 6 inches. [Illustration: FIG. 1162. The Collegiate Church of Arbuthnott. Details of Arch to South Aisle.] The Arbuthnott Missal, already referred to, with its two companion volumes the Psalter and Office of the Blessed Virgin, have been well described by Mr. William MacGillivray. They were specially written for the use of this church by the vicar, James Sybbald. The Missal was finished in the year 1491, and was presented by the writer and the founder [Illustration: FIG. 1163.--The Collegiate Church of Arbuthnott. Interior of Chancel.] of the aisle “to the high altar of the pious Bishop St. Ternan.” The Psalter was finished in 1482, and from internal evidence the last of the three volumes was probably written a short time before the Psalter. [Illustration: FIG. 1164.--The Collegiate Church of Arbuthnott. Corbel and Canopy on Buttress.] From the Register of the Great Seal of date 30th May 1505, it appears that the chapel was then endowed by Robert Arbuthnott, “James Sybbald, Vicar of Arbuthnott,” being one of the witnesses. Sir Robert died in 1506, and the vicar in the year following. The building adjoining the church, seen in Fig. 1158, is the old manse. THE COLLEGIATE CHURCH OF CRICHTON, MID-LOTHIAN. This edifice stands on the south side of the valley where the river Tyne takes its rise, about four miles from Tynehead Railway Station. It is seen from the railway, together with Crichton Castle, from which it is only about a quarter of a mile distant. The building is still in use as the parish church. It consists (Fig. 1165) of a chancel, measuring internally about 44 feet from east to west by about 24 feet 10 inches in width, a central tower about 24 feet square, [Illustration: FIG. 1165.--The Collegiate Church of Crichton. Plan.] and north and south transepts, the total length of which, from north to south, is about 70 feet. The north wall of the nave is erected for a length of about 16 feet, but of the south wall only a few feet have been built.
