I am enabled by the kindness of a friend in Canterbury to place before the Society a tracing and a photograph of the wall painting which has been recently discovered in the apse of St. Anselm's chapel in Canterbury cathedral church, together with a ground plan of the chapel, showing its position. The painting is worthy of attention: first on account of its antiquity, and secondly on account of the singular fact that for seven hundred years it has been hidden from sight.
