The =interior= is chiefly noticeable for its great height, and for its interesting Late Gothic architecture. The patron saints, with their palms of martyrdom, stand on either side of the High Altar. The chapels at the S side should be examined separately: in one is a good stained glass window by Pinaigrier (restored) of the Judgment of Solomon. Notice to what saint each is dedicated. The beautiful flamboyant Lady Chapel, behind the choir, contains good modern frescoes, illustrating the mystic titles of the Blessed Virgin, whose history is shown in the stained glass of the windows, also by Pinaigrier, but very much restored. These scenes the reader will now, I trust, be able to follow for himself—the birth, education, marriage, etc., of the Virgin, with the events of her life as recorded in the Gospels, and her death and assumption. Good Pietà (Christ mourned by angels) as you return on the N side, with some excellent paintings—Martyrdom of St. Juliet, etc. I do not enlarge, as I hope the reader is now able to follow the lead I have given him in previous churches. From St. Gervais, walk a little way along the N side of the church, enclosed in its curious envelope of houses, till you come to the Mairie of the IVth Arrondissement. Then, turn up into the Rue de la Verrerie, along which continue till you reach the side of the church of =St. Merri=, almost hidden from view by a wall of houses. The _façade_ is round the corner, in the Rue St. Martin. This is one of the few remaining mediæval churches in this district. St. Merri (Abbot Mederic of Autun) was a (historical) saint of the 7th century, local and early. He had a hermitage on this spot (then in the woods), and was finally buried here. The shrine over his tomb became the centre of a Parisian cult, and several churches rose successively above his body. The present one was not built till 1520; it is nevertheless a good late Gothic building. But notice the decline from the purity of Notre-Dame and the exquisite lightness of St. Louis’s chapel. Handsome flamboyant doorway, one mass of sculpture: statues of 12 Apostles, with symbols of their martyrdoms, all restored, after being destroyed in the Revolution. The =interior= is interesting, but spoilt in 17th century: good stained glass, badly injured. I bring you here mainly for the sake of the reminiscences. Continue straight on through characteristic old streets, to the modern Boulevard de Sébastopol, which cuts right through the core of Paris. Cross it and take the first turn to the left (as you walk northward) observing the marked contrast of the modern thoroughfare to the narrow streets we have just been traversing. Go along the Rue de la Reynie, and continue for one block, till you see, a little obliquely to your right, the Square des Innocents.
