Among the ecclesiastical remains of this country the seats fixed on the South side the chancels of parochial and other churches, having but very lately been honoured with a share in the labours of your pen, I judged you might receive some trifling gratification in being made acquainted that a religious edifice, at a small distance from this place, was decorated with a specimen of these reliques, nearly unique. This information you were not only pleased kindly to accept, but also to favour me, by signifying your desire that I should give an explanation of this and similar appendages. Stimulated by your wishes, and happy in the proposed opportunity of collecting together my scattered notions on these and one or two relative subjects, I am now about to offer to your consideration the best account I have been enabled to obtain, of the uses for which they were designed by our ancestors; and permit me to observe, on the part of my endeavour, that littie or nothing has been hazarded to conjecture, that what ever favoured of mystery, or was any way phantastical, has been as much as possible avoided; and that, as far as they could be had, vouchers of the most genuine worth in such affairs have been consulted and produced: “Authoribus quidem ad istam sententiam, quam vis obtineri, uti optimis possumus: quod in omnibus causis et debet et solet valere plurimum: et primum quidem omni antiquitate; quæ quo propius aberat ab ortu et divina progenie, hoc melius ea fortasse, quæ erant vera, cernebat.”
