"On the 27th, at half past five in the morning, we attempted to raise our camels at Saffieha by every method that we could devise, but all in vain; only one of them could get upon his legs, and that one did not stand two minutes till he kneeled down, and could never be raised afterward. This the Arabs all declared to be the effects of cold; and yet Fahrenheit's thermometer, an hour before day, stood at 42°. Every way we turned ourselves death now stared us in the face. We had neither time nor strength to waste, nor provisions to support us. We then took the small skins that had contained our water, and filled them as far as we thought a man could carry them with ease; but, after all these shifts, there was not enough to serve us three days, at which I had estimated our journey to Syene, which still, however, was uncertain. Finding, therefore, the camels would not rise, we killed two of them, and took as much flesh as might serve for the deficiency of bread, and from the stomach of each of the camels got about four gallons of water, which the Bishareen Arab managed with great dexterity." It is well known that the camel has within him reservoirs, in which he can preserve water for a very considerable time. In caravans making long journeys from the Niger across the desert of Selima, it has been said that each camel lays in a store of water sufficient to support him for forty days. This statement is probably exaggerated; but fourteen or sixteen days, it is well known, an ordinary camel will live, though he have no fresh supply of water; for when he eats, one constantly sees him throw from his repository mouthfuls of water to dilute his food; and nature has contrived this vessel with such properties, that the water within it never putrefies nor turns unwholesome. The spirits of Bruce's companions now began completely to fail them. The miserable stock of black bread on which they had hitherto subsisted was nearly exhausted, and though they had extracted water from the carcasses or stomachs of the camels, and, like vampires, were thus sucking a horrid nourishment from the bodies of the dead, yet the difficulties which opposed them seemed greater than their strength, and they began to abandon even the hope of ever getting out of the desert. "We were surrounded," says Bruce, "with those terrible and unusual phenomena of nature which Providence, in mercy to the weakness of his creatures, has concealed far from their sight, in deserts almost inaccessible to them. Nothing but death was before our eyes; and, in these dreadful moments of pain, suffering, and despair, honour, instead of relieving me, suggested still what was to be an augmentation to my misfortune; the feeling this produced fell directly upon me alone, and every other individual of the company was unconscious of it.
