The enclosed Communication was sent to me as Chancellor of the Duchy of Lancaster, by Mr. William Hardy, an ingenious and diligent young man, who is one of the clerks in that establishment. As it ascertains a fact (hitherto, I believe, unknown), namely, that the regnal years of Richard the First were calculated, not from his father's death, but from his own coronation, and that before the latter event he had the title of Dominus Angliæ, not Rex Anglorum; I think it worth the notice of the Society of Antiquaries, and in the absence of Lord Aberdeen send it to you, with a request, that at your convenience you will communicate it to that Society.
