Note 65 — Chapter III · THE INTERIOR.
Reading edition
In making excavations for laying the wind-trunk of the organ the exterior of this wall was laid bare and appeared extremely rough. This, however, does not prove that it had never been meant to be seen. It may have been faced with smooth stones, which, just because they were exposed, attracted attention, and were removed by later masons for use elsewhere.—Mr. Micklethwaite.
