South of Katagoum is the Yacoba country, called Mouchy by the Mahommedans. According to accounts received by Clapperton, the people of Yacoba, which is shut in by limestone mountains, are cannibals. The Mahommedans, however, who have an intense horror of the "Kaffirs," give no other proof of this accusation than the statement that they have seen human heads and limbs hanging against the walls of the houses. In Yacoba rises the Yeou, a river which dries up completely in the summer; but, according to the people who live on its banks, rises and falls regularly every week throughout the rainy season. On the 11th of January, the journey was resumed; but a halt had to be made at Murmur at noon of the same day, as Oudney showed signs of such extreme weakness and exhaustion, that Clapperton feared he could not last through another day. He had been gradually failing ever since they left the mountains of Obarri in Fezzan, where he had inflammation of the throat from sitting in a draught when over-heated. On the 12th of January, Oudney took a cup of coffee at daybreak, and at his request Clapperton changed camels with him. He then helped him to dress, and leaning on his servant, the doctor left the tent. He was about to attempt to mount his camel, when Clapperton saw death in his face. He supported him back to the tent, where to his intense grief, he expired at once, without a groan or any sign of suffering. Clapperton lost no time in asking the governor's permission to bury his comrade; and this being obtained, he dug a grave for him himself under an old mimosa-tree near one of the gates of the town. After the body had been washed according to the custom of the country, it was wrapped in some of the turban shawls which were to have served as presents on the further journey; the servants carried it to its last resting-place, and Clapperton read the English burial service at the grave. When the ceremony was over, he surrounded the modest resting-place with a wall of earth, to keep off beasts of prey, and had two sheep killed, which he divided amongst the poor. Thus closed the career of the young naturalist and ship's doctor, Oudney. His terrible malady, whose germs he had brought with him from England, had prevented him from rendering so much service to the expedition as the Government had expected from him, although he never spared himself, declaring that he felt better on the march, than when resting. Knowing that his weakened constitution would not admit of any sustained exertion on his part, he would never damp the ardour of his companions.
