extending 3 ft. 5 in. to the south, and a medieval wall or buttress reaching 6 ft. 9 in. to the east. Here also imbedded in the wall is a massive circular Roman pillar, at the foot of which has been found the upper portion of an apparently Roman phial.
  The foundations of the old chancel wall (on which that of the later church has not been evenly and symmetrically placed) start 10 inches farther in than those of the nave wall, and can be traced for 12 or 13 feet more till we detect something like the commencement of the apse; but at this interesting point we are warned off by the owner of the adjacent ground.
   We will now return to the southern chantry or aisle, which is of identically the same size as the western porch.
   Thorn goes on to say, after the passage I have already quoted, "There is still extant an altar in the southern porticus of the same church, at which the same Augustine was wont to celebrate, where formerly had stood the idol of the king—at which altar, while Augustine was celebrating mass for the first time, the

devil, seeing himself driven out  from the home which he had inhabited for long ages, tried to overturn from the foundations the aforesaid church: the marks of which are still apparent on the exterior eastern wall of the abovementioned porticus."
   In an engraving, bearing the date 1784, the so-called devil's marks are shewn; and I have little or no doubt that the porticus mentioned by Thorn is the same which we have excavated. We cannot call it a porch, as there are no traces of an external door.
   Now the walls of this porticus are built chiefly of Roman tiles, coated in the lower part with a facing of concrete, and in the upper parts with thick plaster. In it are the remains of a rude altar, with the pavement of fifteenth century tiles complete on either side: the altar, 4 ft. 4 in. by 2 ft. 2 in. in size, of an uncertain date, possibly contemporary with the pavement, but built on older foundations. In addition to the later fifteenth century doorway on the northern side, there are close to it distinct traces of an earlier entrance
