indifferent about scorpions and other wild animals." He had greater difficulty in accustoming himself to the sociable habits of the snakes, who used to glide about amongst tents and baggage, and by whom, in the course of the expedition, a great number of persons were bitten. On the 12th April "Mohammed Ladham sent us a remarkable scorpion--pity that it is so much injured--almost two fingers long, black-brown, tail and feet covered with prickly hair, claws as large as those of a small crab.... We had laid us down under a green tree beside a cotton plantation, whilst our servants unloaded the camels and pitched the tents, when a snake, six feet long, darted from under our carpet, passed over my leg, and close before my brother's face. But we were so exhausted that we lay still, and some time afterwards the snake was brought to us, one of Schech Defalla's people having killed it." About noon next day a similar snake sprang out of the said Defalla's own tent; it was killed also, and found to measure six feet two inches. The soldiers perceiving that the German physician and his brother were curious in the matter of reptiles, brought them masses of serpents; but they had got a notion that the flesh was the part coveted (not the skin) to make medicine, and most of the specimens were so defaced as to be valueless. Early in May "some soldiers assured us they had seen in the thicket a serpent twenty feet long, and as thick as a man's leg; probably a species of boa--a pity that they could not kill it. The great number of serpents with dangerous bites makes our bivouac very unsafe, and we cannot encamp with any feeling of security near bushes or amongst brushwood; the prick of a blade of straw, the sting of the smallest insect, causes a hasty movement, for one immediately fancies it is a snake or scorpion; and when out shooting, one's _second_ glance is for the game, one's _first_ on the ground at his feet, for fear of trampling and irritating some venomous reptile." As we proceed through the volume we shall come to other accounts of beasts and reptiles, so remarkable as really almost to reconcile us to the possibility of some of the zoological marvels narrated by the Yankee Doctor Mayo in his rhapsody of Kaloolah.[4] For the present we must revert to the business of this curiously-conducted campaign. As the army advanced, various chiefs presented themselves, with retinues more or less numerous. The first of these was the Grand-Shech Mohammed Defalla, already named, who came up, with a great following, on the 28th March. He was a man of herculean frame; and assuredly such was very necessary to enable him to endure in that climate the weight of his defensive arms. He wore a double shirt of mail over a quilted doublet, arm-plates and beautifully wrought steel gauntlets; his casque fitted like a shell to the upper part of his head, and had in front, in lieu of a visor, an iron bar coming down over the nose--behind, for the protection of the
