We will first refer for details to the north arm; of which the western aisle is open, and is lighted by three Norman windows, all of which have been recently filled with stained glass: The south window--executed by M. Lusson, of Paris; the subjects taken from the Parables; as a memorial of the Rev. A. Moore, of Walpole, who designed and executed three windows in the Cathedral. The middle window, by the same artist; subject, the Good Samaritan: given by John Muriel, Esq. The northern window was executed by the Rev. A. Moore; the subject taken from the parable of the Prodigal Son. At the north end of the Transept is a small colonnade, the arches of which are irregular, those opposite the lower windows being higher than the others to allow free passage to the light. At the north-east corner is a doorway communicating with a staircase leading to the upper parts of the church. In the year 1699 the fall of a portion of the north-west corner took place, but it was so well rebuilt as not to be discernable in the interior. The windows in the triforium on the east side are original; those of the triforium on the west side, and the upper ones at the north end, are Perpendicular insertions; the rest are all in their original form, or have been restored to it; those in the north end have been filled with stained glass: The two lower, and the western window of the second tier, by Mr. Wailes, at the cost of the late Canon E.B. Sparke. The eastern window of the second tier, by the Rev. A. Moore. The subjects of these four windows are incidents in the history of St. Paul. The windows in the upper tier--by Messrs. Ward and Hughes--also at the cost of the late Canon E.B. Sparke, contain figures of eminent persons in New Testament history, with arms, &c. in the tracery. Those in the western window represent Silas; Clement, bishop; Apollos; Judas Barsabas; Dionysius, areopagite; and Philip, deacon: in the eastern window, Titus, bishop; St. Paul; Timothy; St. Mark; St. Barnabas; and St. Luke. The eastern aisle is divided by walls behind the columns into compartments; the northern one forms a communication with the entrance to the Lady Chapel; the middle one a vestry for the Grammar Scholars; and the third a vestry for the Lay-Clerks; remains of fresco paintings may be seen on the walls of both these compartments. The stained glass window in the middle compartment contains subjects from the history of our Saviour; executed by Messrs. Clayton and Bell: presented by--Heywood, Esq., as a memorial to his mother. The window in the third compartment, by the same artists, represents the Entombment and the Ascension, and is the gift of C.L. Higgins, Esq., of Turvey Abbey. The floor of this portion has been recently re-laid by the munificence of the late Canon E.B. Sparke.
