As will be seen from the Plan ([Fig. 350]), the central part consists of four rounded shafts, having a boldly pronounced base moulding. The basin is in the form of a Norman cushion capital, with four rounds on each face, the abacus having a splayed projection of about a quarter of an inch. The font has evidently been meant to be placed against a wall, as all its parts—base, shaft, and capital—abut against a square haffit perfectly plain on the back, to admit of its standing in such a position.

The structure, which is barrel vaulted, is of considerable age, but it is not the chapel erected in the thirteenth century; and as the font is a work of
