The authors beg again to tender their acknowledgment of the assistance they have received from many quarters. They have especially to thank Mr. T. S. ROBERTSON, Architect, Dundee; Mr. WILLIAM GALLOWAY, Architect, Wigton; and Mr. R. BRUCE ARMSTRONG, for the drawings and descriptions they have kindly contributed, and which are referred to in the text. To Mr. JOHN HONEYMAN and Mr. T. L. WATSON, Architects, Glasgow, they are also indebted for assistance in connection with Glasgow Cathedral. * * * * * Since the description of St. Andrews Cathedral in this Volume was written, considerable progress has been made with the works referred to in the text, as being carried on for Lord Bute by Mr. Kinross, Architect, and several new points have been disclosed. The west doorway from the cloister into the nave (which is in a modern vinery) has been opened up on the south side, and its massive first pointed architecture has been shown. The arch is pointed, and the details (including dog-tooth enrichments) correspond in style with the entrance to the chapter house (see Fig. 452). The whole of the crypt of the refectory (see Fig. 454) has been excavated and the pillars uncovered, showing that there were two rows of pillars and three vaults in the width of the building. The pillars, which are round, have been restored so far as they were incomplete, and so have the groined arches, the new work being executed in red sandstone, so that it may be easily distinguishable from the old work, which is of a light coloured freestone. The masonry of the old pillars being considerably shattered, it has been found necessary, in restoring the crypt, to insert an iron column in the heart of each pillar, in order to give them sufficient strength to carry the weight of the vault. It is not known to what use this crypt was applied. In the east range of buildings running south from the chapter house, the excavations have been continued, and the pillars of a vaulted chamber below the dormitory have been revealed. As this chamber contains a fireplace, it may possibly have been the day room or calefactory of the canons, as only one fireplace (and that in the calefactory) was allowed in the monasteries. There is, however, some doubt as to whether this fireplace is original. At the south end of this chamber a deep drain or water channel, carefully built with ashlar, has been found. This was, doubtless, the main sewer of the monastery, through which there flowed a constant stream of water. The stream which fed the mill race (see Fig. 457) is not far distant. The latrines were, without doubt, situated above this sewer.
