six hours' ride, and terrible loss of leather, the blood running down into his stockings. Partly on his dromedary, partly on foot, he managed to follow his leader through this second day's march, at the cost of another night's fever, but in the morning he was so weak that he was obliged to take boat and complete his journey to Damer by water. Of more slender frame and delicate complexion than his brother, the poor doctor was evidently ill-adapted for roughing it in African deserts, although his pluck and fortitude went far towards supplying his physical deficiencies. Most painful are the accounts of his constantly recurring sufferings during that arduous expedition; and one cannot but admire and wonder at the zeal for science, or ardent thirst for novelty, that supported him, and induced him to persevere in the teeth of such hardship and ill-health. At Damer he purchased a small dromedary of easy paces, and left the Bascha's rough-trotting gift for his brother's riding.

At three in the afternoon of the 20th March, a cannon-shot gave the signal for departure. The Wernes' water-skins were already filled and their baggage packed; in an instant their tents were struck and camels loaded; with baggage and servants they took their place at the head of the column and rode up to the Bascha, who was halted to the east of Damer, with his beautiful horses and dromedaries standing saddled behind him. He complained of the great disorder in the camp, but consoled himself with the reflection that things would go better by-and-by. "It was truly a motley scene," says Mr Werne. "The Turkish cavalry in their national costume of many colours, with yellow and green banners and small kettle-drums; the Schaïgië and Mograbin horsemen; Bedouins on horseback, on camels, and on foot; the Schechs and Moluks (little king) with their armour-bearers behind them on the dromedaries, carrying pikes and lances, straight swords and leather shields; the countless donkeys and camels--the former led by a great portion of the infantry, to ride in turn--drums and an ear-splitting band of music, The Chabir (caravan-leader) was seen in the distance mounted on his dromedary, and armed with a lance and round shield; the Bascha bestrode his horse, and we accompanied him in that direction, whilst gradually, and in picturesque disorder, the detachments emerged from the monstrous confusion and followed us. The artillery consisted of two
