We have already described the square-headed doorway, but may add that (during the present spring) the lepers' window has been traced inwards to a depth of 1 ft. 8 in. from the exterior of the wall. From this _square-headed_ doorway the _semi-circular_ one (commented on in our description of the exterior of the church) is 4 ft. 2 in. distant. Beyond this the early brick wall extends eastward for 6 ft. 9 in. till we reach a break in it, which was clearly the termination of the original chancel. For the last two feet the work is somewhat irregular, and from this circumstance, and from some evidence discovered at this spot on the outside, it has been conjectured that here we have the beginning of a Roman apse (_cf._ Appendix C). Eastward of this break, the walling is of different workmanship, showing with the mortar-joints six bricks to a foot, and after 3 ft. 5 in. we come to a =Sedile=, which was blocked up with mediæval brickwork, and opened out a short time ago. It had apparently a slightly pointed arch, of which about five inches have been cut away. The springing line is about 2 ft. 9-½ in. above the seat; the radii are about 3 ft. 9 in., their centres being on the springing line. This would fix its measurements as follows:--Span, 5 ft.; depth, about 1 ft. 3 in.; height from seat to springing line, 2 ft. 9-½; in.; and from seat to apex, about 6 ft. 4 in. A difficulty has arisen as to the date of the sedile from the fact that the top of it has been cut away by the insertion of a lancet window, appearing at first sight to belong to the Early English period, so that the sedile would seem as if it must be of an earlier date than the window. But Mr Livett, though believing it not impossible that the sedile and lancet window were built at the same time, and the sill of the window altered afterwards, thinks it more probable that the sedile and its adjoining brickwork were built late in the twelfth century, and the lancet window inserted subsequently, perhaps in the fourteenth century. The position of the sedile would seem to point out that the high altar stood, in Early English times, immediately east of the step whereon the present altar rails are placed. The east wall of the church was partially pulled down and rebuilt about fifty years ago, to which period we owe the pseudo-Norman work of the reredos. The lancet windows were filled at that time with an ill-drawn representation of the Crucifixion in the centre, and on each side with the Ten Commandments, which were slowly fading away. Inside the altar rails is an =aumbry=, 15 by 14 inches, with a wooden door of "linen pattern," dating probably from the time of Henry VII. The recess inside the door extends to a depth of 18 inches, and is still in use.
