Horneman was one of the unlucky four sent out by the African Association to find the source of the Niger and the direction of its flow. During his first expedition he reached Murzuk, but was forced to retreat to Tripoli. On his second attempt however he died somewhere on the Niger, without being able to inform the world of his accomplishments. Cox I, p398.
