"These piers were about 4 feet high, 4 feet to 6 feet long, and 1½ foot to 2 feet broad; and there was a passage of from 1 foot to 2 feet in width between the wall and them."
"On a small, flattish terrace, where the hill sloped steeply, an area had been cleared by digging away the bank, so that the wall of the house, for nearly half its circumference, was the side of the hill, faced with stone.... The hypogeum or subterranean gallery is on a level with the floor, pierced towards the hill, and is entered by a very small doorway [marked d on Ground Plan, Plate XI.].... It is but 18 inches high and 2 feet broad, so that a very stout or large man could not get in." (Op. cit., pp. 166, 167.)

"An ancient dwelling, semi-subterranean, exists at Nisibost, Harris [and is described in vol. iii. of the Proceedings, p. 140].... A still finer example exists near to Meall na h-Uamh, in South Uist.... The bo'h, or Pict's house, as it would be called in the Orkneys—but the name is unknown in the Long Island—that I am about to describe lies less than half a mile above the shepherd's house; but so little curiosity had that individual that he was entirely unacquainted with it; and I believe it would never have been found by us but for a little terrier (in its etymological sense, of course) of a daughter. The child was only acquainted with the two here drawn [of which the other—viz., Uamh Sgalabhad, is here reproduced as Plate I., frontispiece]; but there may be many more waiting the researches of the zealous antiquary."
