has jambs of Roman bricks, with a lintel and sill formed of massive blocks of green sandstone, much worn by weather. Internally it seems 4 ft. 7 in. at the top, but this may be accounted for by the fact that in later times it was partially blocked up by a stone sarcophagus, and other material: and on one side of the upper portion of the doorway, and extending beyond it towards the west, there was opened a low side-window, the western splayed jamb of which is still remaining, with the original plaster. This may perhaps have been a "Lepers' window" commanding a view of the altar of St. Mary, occupying the site of the present pulpit. This square-headed doorway is certainly contemporaneous with the surrounding wall. When it was first exposed, we found in it the skeleton of a sparrow! [Illustration: S.-W. EXTERIOR OF CHANCEL. (From a water-colour by Mrs M. Parry.)] [Illustration: St. Martin's, Cant.--Adjunct. Section of foundations & portion of wall, with face of chancel wall above shewing signs of the bonding.] Near these square-headed doorways there were discovered underground the remains of two walls, running at right angles to the chancel, and forming two sides of an _adjunct_ or side chapel, the southern side of which has been destroyed in the process of digging graves. These walls are 4 ft. 9 in. apart, and are each of them 26 in. wide, built entirely of Roman bricks. The western wall runs eight inches beneath the eastern angle-wall of the nave. Between the walls there is still existing part of a flooring of _opus signinum_. There can be no doubt that this _adjunct_ is of the same workmanship, and the same date, as the early brick wall of the chancel. The foundations of both are precisely similar, and are constructively bonded together--the walls rest upon a footing-course of one brick, which forms the top of a shallow foundation of flints and stones. The brick-footing is continued along the chancel wall under the sill of the square-headed doorway, and is irregular in its projection. A careful examination of the existing face of the chancel wall above the remains (which was made by Mr Livett), shows that the eastern wall of the _adjunct_ above ground, now destroyed, was originally bonded into the chancel wall. Every alternate course shows a broken brick, and every intermediate course the clean edge of a brick. This bonding cannot be traced above a line on a level with the lower edge of the lintel of the square-headed doorway of the chancel. What the purpose of this _adjunct_ was, we cannot positively determine. It was suggested by the late Archbishop of Canterbury (who took the warmest interest in the church, and also keenly watched the progress of the excavations) that it was used as a place for baking the holy bread employed at the celebration of the Mass. It is more probable, however, notwithstanding its diminutive size, that it was a side-chapel with its altar.
