I have the honour to forward for the consideration of the Society of Antiquaries a Drawing of the Tessellated Pavement recently found between Bishopsgate Street and Broad Street, under the vaults of the south-eastern area of the late Excise Office. A small plan which accompanies the drawing (Pl. XVIII.), will show the exact position of the pavement itself, relatively to the adjoining street and to the buildings of the Excise Office. It is a commonly received opinion, that the late Government edifice occupied the site of the house and premises of Sir Thomas Gresham only; and it may be therefore convenient to explain that subsequently to the purchase by the Government from the trustees of Sir Thomas Gresham of the buildings of Gresham College, in 1768, they bought an inn adjoining southward, called the Sun; and these two premises together constituted the area of the late Excise Office. I cannot exactly define the boundary of the two properties, but I have no doubt that the site of this pavement was under the Sun inn portion of it, and did not form any part of the land purchased of the Gresham trustees. In removing the Excise Offices we began from Threadneedle Street, and in taking up the foundations of the main buildings, nothing of any interest was found; but, as we proceeded towards Bishopsgate Street, it was evident that we were approaching foundations and remains that were of a much earlier construction.
