JAMES RICHARDSON, the enterprising African traveller, died on the 4th of March last, at a small village called Ungurutua, six days distant from Kouka, the capital of Bornou. Early in January, he and the companions of his mission, Drs. Barth and Overweg, arrived at the immense plain of Damergou, when, after remaining a few days, they separated, Dr. Barth proceeding to Kanu, Dr. Overweg to Guber, and Mr. Richardson taking the direct route to Kouka, by Zinde. There it would seem his strength began to give way, and before he had arrived twelve days' distance from Kouka, he became seriously ill, suffering much from the oppressive heat of the sun. Having reached a large town called Kangarras, he halted three days, and feeling himself refreshed he renewed his journey. After two days, during which his weakness greatly increased, he arrived at the Waddy Mallaha. Leaving this place on the 3d of March, he reached in two hours the village of Ungurutua, when he became so weak that he was unable to proceed. In the evening he took a little food and tried to sleep--but became very restless, and left his tent supported by his servant. He then took some tea and threw himself again on his bed, but did not sleep. His attendants having made some coffee, he asked for a cup, but had no strength to hold it. He repeated several times, "I have no strength;" and after having pronounced the name of his wife, sighed deeply, and expired without a struggle about two hours after midnight. Early in the morning, the body wrapped in linen, and covered with a carpet, was borne to a grave four feet deep, under the shade of a large tree, close to the village, followed by all the principal Sheichs and people of the district. * * * * *
