^{page 1 note 1} I am indebted to Mr. Ernest Woolley, a past Master of the Merchant Taylors’ Company, for admirable photographs of various parts of the buildings, and the authorities of the Guild have furnished a most accurate drawing of the north side by their surveyor Mr. Mew (pl. I), also other photographs.

Allen shows the beginnings of two diagonal ribs, suggesting a fourth bay, which was perhaps a mistake of the draughtsman. No allusion is made to it in the text. He does not give the points of the compass, but in Clode's Memorials the plan is copied, this end being marked ‘north’. The existing bays are immediately east of the hall.

^{page 15 note 2} This tower also contained the bell called ‘Edward of Westminster’ or ‘Great Tom’, which was presented by William III to St. Paul's Cathedral. The clock-tower was granted to St. Margaret's parish in 1698, and pulled down soon afterwards. Its position is shown on a plan of the precincts of Westminster Abbey in Sandford's Coronation of James II, 1687. It was rather less than 200 ft. north of Westminster Hall.

^{page 21 note 1} The points of the compass are used approximately. In fact the building stood, not north and south, but north-west by south-east. In this paper south means towards Holborn, north means towards Highgate, and so on.

^{page 25 note 1} ‘Cespool’ has not the unpleasant meaning of our modern word cesspool. It is equivalent to cesperill or suspiral, which Sir William Hope, in his paper on the water system of the Charterhouse, explains as a vent to avoid the danger of a pipe bursting by pressure of air or water. It seems likely that they served other useful purposes.
