4 inches thick; the soctjud uv contial division is 5 feet thick, and the external 

 division, 4 feet 5 inches thick — total thickness, 12 feet 9 inches. The two 

 external divisions are hero raised to the height of 18 feet; but the internal 

 division is at present only 7 feet high ; bvrt it is j)robable that it was originally 

 many feet higher, thongh, I think, never so high as the two external parts, 

 as I find in all the other forts that the internal division is generally 4 feet 

 lower than the other two, which are always carried to the same height." 

 [pp. 206, 207 ; map and some comments are next given. Some pencil-notes 

 give the measurements which he uses later on.] [p. 208.] The doorway 

 which led into this keep is still nearly perfect ; it is placed in the north-east 

 side, facing the Aran lighthouse, which is situated on the highest point of 

 the island. It is nearly stopped up on the inside with stones which fell from 

 the top of the wall ; I removed them on the outside down to the solid rock 

 on which the wall is built, and found the doorway to measure in height 

 exactly 5 feet. [He then gives the dimensions and rise of each of the four 

 lintels.] The doorway would be 21 inches higher on the inside than on the 

 outside were it not that the solid rock on which the wall is built rises in 

 proportion. ... [p. 209.] At this doorway the external part of the wall 

 only remains perfect, measuring 4 feet 5 inches in thickness, and the other 

 two divisions are nearly level with the area of the fort, but immediately to 

 the north and south of it they are tolerably perfect. 



" In the north-west side of this ring there is a passage, leading from the 

 inside into the thickness of tlie wall to the extent of 5 feet 6 inches, measuring 

 2 feet 9 inches in width at the top, 3 feet 7 inches from the bottom to the 

 roof where it is covered by large stones laid horizontally across. . . . 



[p. 210. Middle Wall.] " Outside the internal keep are the remains 

 of a strong cyclopeau wall which surrounds it at u'regular distances. 

 Immediately to the west, near the cliff, it is within 28 feet of the keep. 

 To the north and by west is 32 feet from it, and to the north-west, 

 42 feet 6 inches. To the north from the keep this wall is in tolerable 

 preservation, for here its original thickness and pei'haps height remain. It 

 is 6 feet thick and 12 feet high, and well faced inside and outside with 

 stones of considerable size. It consists of two distinct walls, one built up 

 against the other. ... A line drawn from this part of the wall to the 

 doorway of the interior fort, or keep, measures 131 feet. In the north-east 

 part of this external wall there is a doorway now much destroyed. It is 

 4 feet 7 inches in width, and the wall is here 8 feet 2 inches in thickness. 

 A line drawn from this doorway to that of the internal fort or keep measures 

 235 feet. At the distance of a few feet to the east of this broken doorway 

 this wall forms an angle from which a straight line, drawn to the doorway of
