seen in the south side, and with the one in the east wall of the chancel, judging from which it was probably at this later period that all the present windows, seen in Fig. 292, were inserted. The original windows were, doubtless, the usual small windows found in Norman churches, and when they came to be enlarged, the builders probably increased the buttresses to compensate for the weakening of the wall, and added the conical finials on them and on the gables (see [Fig. 292.]). It is obvious that to this period also the upper part of the tower belongs. The lower part of the tower, although not of the original structure, is, we are inclined to think, of considerable antiquity; it opens into the church with a plain, round arch. The staircase shown in it and on the north aisle lead to galleries.
