The following morning the whole assembled "by orders" on a place some distance from the town. Arranged in a large crescent, Sheik Jamma addressed his warriors in these words: "We are a strong and mighty people, unequalled in horsemanship and in the use of the club and the spear!" Moreover, (said he), they had increased their power by adopting the system of fire-arms, the real strength of the Turks. He was all-confident that the very sight of their gunmen would strike terror into every neighbouring tribe. He ended by proposing a raid into Abyssinia, and said: "We will take cows, slaves, horses, and mules, and please our master the great Theodore by plundering his enemy Tisso Gobazé!" A wild _feu-de-joie_, and a terrible roar, from the excited crowd, informed the old Sheik that his proposal was accepted. That very same afternoon they started on their expedition, and probably surprised some peaceful district, as they returned after a few days, driving before them several thousand heads of cattle. Metemma, from May to November, is very unhealthy. The principal diseases are continued, remittent, and intermittent fevers, diarrhoea, and dysentery. The Takruries are a tough race, and resist well the noxious influences of the climate; but not so the Abyssinian, or the white man: the first is almost certain to die should he attempt to spend the dreaded months in the malarious low country, the second most probably will suffer much in health, but resist for a season or two. During our stay, I had many demands for medicine. Large, cake-like spleens were greatly reduced by local applications of tincture of iodine, and the internal administration of small doses of quinine and iodine of potassium. Chronic diarrhoea yielded readily to a few doses of castor oil, followed by opium and tannic acid. Acute and chronic dysentery was treated by ipecacuanha, followed by astringents. One of my patients was the son and heir of the Sheik. He had been suffering for the last two years from chronic dysentery; and although under my care he entirely recovered, his ungrateful father never even thanked me for all my trouble. Simple ophthalmia, skin diseases, and glandular swellings were also common. The Takruries have no knowledge whatever of medicine: charms are here, as throughout the Soudan, the great remedy. They are also used as preventatives to keep off the evil eye, bad spirits, and genii of different sorts; for these reasons almost every individual-- nay, cattle, mules, and horses, are covered with amulets of all shapes and sizes.
