A copy of Henry O'Brien, The Round Towers of Ireland ... (London, 1834) with extensive annotations, most of which are undoubtedly in the same unidentified hand (see pages 146 and 387 for what may be clues as to the annotator's identity). A note on page 505 evinces an acquaintance with the Welsh language but may well have been added by someone other than the main annotator.
