rays, on tlie floor and "^alls, for vliich. object the narro-svness of the 

 opening would he more advantageous than if it were wide, as at 

 present is the case. 



The only other opening in the walls of the building is a small 

 square cavity, situated in the northern wall, quite near the north- 

 west interior angle of the building, and situated at a height of 

 273 cm. from the ground. Its dimensions are about 40 cm. by 40 cm. 

 It was originally evidently a recess in the nature of a cupboard, and 

 did not then extend through the thickness of the wall ; since on the 

 outside, as it presents itself at present, it is represented by a hole, the 

 place from which a stone had been forced out. 



On the walls, in the interior, are to be seen the remaining traces 

 and patches of plastering, leading to the presumption that the greater 

 part of these surfaces had been so treated. On the interior face of 

 the west wall, this plastering shows the traces of a floor having once 

 existed at the height of 273 cm, from the present ground, and in 

 the south-west corner at this height, appears a rectangular space 

 measuring 135 cm. by 98 cm., marked on the plastered surface, 

 as if some article of furniture had been in position there (see 

 PI. XT., fig. 2). 



The fire-place in the eastern wall is mentioned by "Wakeman as 

 having been made by the workmen who took up their dwelling in the 

 old church during the building of the ISIartello Tower. The recessed 

 space above it is probably original, and is unsymmetrical in its lines, 

 as regards the vertical axis of the wall face. The workmanship is 

 very rough, as is also that of the arching. There is a crack in this 

 face over this recess, as if there were a void space in the wall, 

 such as a chimney-flue. 



There is every reason to suppose that the original roof was of 

 stone slabs, probably of the chiastolite mica-schists that outcrop on 

 Killiney shore, possibly of the ordinary mica-schist to be found in 

 connexion with the granite there. "What was the form of the 

 termination of the eastern gable can only be a matter of conjecture 

 at present; but it supported the roof at all events, and may have 

 presented an opening just imder the ridge of the roof, or this eastern 

 gable may have carried a belfry or opening such as that still remain- 

 ing on the western gable. "Wakeman considers this latter belfry to 

 be a recent addition; but the appearance of the masonry hardly 

 supports that opioion ; while, on the other hand, the thicknesses of 

 the two gable walls at the base, 91 cm. (about one-tenth greater than 

 that of the two side walls), would point towards the presumption
