a mountainous region in the interior of Africa, which Mr Horneman calls the most remarkable region which came under his observation during his journey. It presents such a rugged, broken and terrific scene, as naturally leads to the supposition, that its surface has been, at some remote period, convulsed by volcanic eruptions. The face of the whole country exhibits continued ranges of hills, some not more than 12 feet above the plain, and others extremely lofty.

Contiguous to this region, which is called Harutsch-el-assuat, or Black Harutsch, lies the White Harutsch or Harutsch-el-abiat. This latter country is a vast plain which spreads to the mountains rising towards Fezzan, and is interspersed with isolated mountains.

Many of the hills contain petrifications, and the matter of which they are composed is friable limestone, in which the petrifications are very loosely imbedded, and may be taken out with ease. In these Mr Horneman found, among other marine productions, the heads of fishes so large, that one of them would have been a sufficient burden for an ordinary man. Vast numbers of shells are likewise found in the adjacent valleys, which have the appearance of being glazed, and have a vitreous fracture. It is not the abode of man, but the Arabian caravans frequently pass through it. The extent of this region is said to be seven days' journey from north to south, and five days from east to west. It lies between 15° and 20° E. Long. and between 28° and 32° N. Lat. Horneman's Travels, p. 48.
