Burton's 1877-78 second expedition into the Midian, which, like his first in 1877, was financed by the Khedive in Cairo as a search for gold. He mapped a 600-mile route through the northern and southern Midian recording its ruined ancient cities. For the Khedive in Cairo he brought back twenty-five tons of minerals to be assayed. For himself, he seriously considered forming a company to exploit the oil resources of the Midian but nothing came of it. Only 1000 copies were printed. A tall fresh copy. Penzer, pp 96-97.
