built on the site of the old walls, and show that the choir consisted of five bays, with an apse. The total interior length from the east wall of the apse to the tower is about 102 feet. It may be mentioned that the total internal length of the existing church from the west end of the nave to the apse is about 234 feet. The crypt was approached by two stairs, one from the north and another from the south aisle of the choir. These are now swept away, and only their round arched openings remain as recesses in the walls of the crypt. As these recesses are at a considerable height, most of the steps were probably in the crypt. The stairs shown on the Plan with the windows and doors are all quite modern. The latter lead out to the street, which is at the level of the floor. The length of the crypt (which corresponds with the width of the choir) is about 65 feet. The crypt consists of one central and two side aisles, with an eastern apse. The plan of these divisions indicates that the central aisle of the choir was only about 3 feet wider than the side aisles, a very unusual arrangement, the side aisles being generally much narrower than the central one. The width of the crypt is about 16 feet, and the length at the apse is about 36 feet 6 inches. It is internally a very picturesque and interesting structure, but it has been badly treated at the time of the rebuilding of the choir. The wonder is that it escaped from being rebuilt, like the rest of the church. It is at present proposed to restore the building by removing the lath and plaster from the walls, and laying the floor at the original level, and also to fill the windows with stained glass. We may express the hope that before this is done the distressing effects of the stained glass in the crypt of Glasgow Cathedral will be duly considered. [Illustration: FIG. 388.--St. Nicholas’ Church. Details of Piers of Crossing.] The roof is groined throughout, the three compartments in the length (Fig. 392) being separated by pointed arches, which spring from moulded caps on octagonal responds. The ribs are the same in all the compartments, except that in the centre and north a length of the ridge rib is omitted (see Plan). The opening into the apse has a stunted [Illustration: FIG. 389.--St. Nicholas’ Church. North Transept.] round arch (Fig. 393), and is a prominent example of the love of the Scottish builders for this form of arch all through the Gothic period. This is the only place in the crypt where the width is sufficient to allow [Illustration: FIG. 390.--St. Nicholas’ Church. Clerestory Window.]
