"The form of the _ground-plan_ of the _early-brick_ building (a term we have agreed to use in reference to the masonry at the western half of the existing chancel) has not been positively determined. Its eastern termination was destroyed in the extension of the building in the late twelfth or early thirteenth century, and its western end disappeared at a far earlier date. "The probability that this early-brick building terminated eastward in an apse is established by a careful consideration of the existing remains of the south-east angle of that building, marked at the present time by a narrow pilaster-buttress facing south, near the middle of the south wall of the chancel. This buttress has been modernised, with its Caen-stone quoins: but its foundations, lately exposed, prove that it accurately represents, in dimension and position, an original early-brick buttress. The sketches (given above) illustrate the features which indicate an apsidal termination of the original building. _No. 1_ is a plan of part of the existing south wall of the chancel. It shows the buttress, and, immediately east of it, the junction of the twelfth-century wall with the early-brick wall. To complete the description of existing features, it may be added that the inner face of the wall (above some apparent foundations there underneath the floor of the chancel) is rough--an evident sign that early-brick masonry attached to this face was removed when the extension of the chancel was made. Towards the east there are no signs to indicate where the destroyed masonry stopped; but towards the west there are, in the arrangement of the bricks, marks of a vertical bonding-line, exactly corresponding in position with the western face of the buttress on the outside. In that place, then, the destroyed masonry originally rose with a clear face looking west. How far that masonry ran towards the north there is nothing to show. It is a significant fact--proved by the hole lately made through the twelfth-century wall, at its junction with the earlier work--that the end of the early-brick wall is in plane with the eastern face of the external buttress, and that no buttress ever existed on the eastern face of the angle. "All these features are consistent with the supposition that the early-brick building terminated eastwards in an apse, and consistent with that supposition only. Had the east end been square, the natural treatment would have been as shown in _Sketch No. 2_--there would remain indications of a buttress on the eastern side of the angle, the vertical bonding-joint would be seen farther west, to allow for an end wall of the same thickness (2 ft. 2 in.) as the side-wall--and the existing buttress, instead of being narrow, would probably be of the same breadth as the walls.
