I have much pleasure in communicating to you, on behalf of the Society of Antiquaries, the following observations which have lately been made in the course of our operations at the New Houses of Parliament, or, more properly, at her Majesty's Palace at Westminster. Having had occasion to remove a portion of the old Crypt of St. Stephen's Chapel during the past summer to make way for the new buildings now in progress, sundry curious and beautiful remains were discovered, which I have thought desirable should become the subject of the accompanying sketches, and which I have much pleasure in presenting to the Society, together with a small capital of one of the columns, and an ancient key of singular shape found in the excavations.
