Whilst at Constantinople, we saw the exterior of a few of the principal public buildings in the city, and from the Mosque of San Sophia, which stands upon high ground, overlooking the Bosphorus, had a distant view of the Barracks at Scutari, where Florence Nightingale and her helpers so nobly attended the sick, wounded, and dying soldiers, who fought during the Crimean war. An ancient Egyptian Obelisk from Cairo, about 3,000 years old, covered with hieroglyphics, was also pointed out. The Bazaars of Constantinople, consisting of lofty stone cloisters or arcades, lighted from the top by domes, are extensive, numerous, and very oriental in appearance. Each trade has its particular quarter, and the various dealers have small shops with rooms behind them for their wares, which are often of a costly and valuable description. On the afternoon of April 14th, a religious service of the dancing Dervishes was held at one of their Convents, within a few minutes walk of our hotel. There were 18 performers altogether, who wore brown mantles, and high, round caps made of felt. At a particular signal, they all fell flat upon their faces; but afterwards rose, and walked a few times round the room, with folded arms, bowing and turning slowly many times. Their mantles were then suddenly cast off, when they appeared in long, full, bell-shaped petticoats and jackets, and, after stretching out their arms to the utmost, began gravely and deliberately to dance and revolve (that is, to spin round and round like a top) for about fifteen or twenty minutes, as rapidly as possible. The sight was instructive, inasmuch as it gave rise to a feeling of the deepest gratitude to God that the wild, religious delusions of these poor Dancing Dervishes were not ours. "Who maketh _thee_ to differ from another, and what hast _thou_ that thou didst not receive," should ever be the language of our hearts. The howling Dervishes we did not see, but heard that they carry on their religious performances at Scutari.
