IN the volume before us Dr. Blanckenhorn has collected the results of his researches into the geology and natural history of Palestine, the latest of which occupied the first half of 1908. These have enabled him to give a much more minute account of the geology of the region than any of his predecessors, to lay down more accurately the boundaries of the several formations, and to trace a number of important faults. As his map shows, the Syrian upland on either side of the Jordan valley from the southern end of the Dead Sea almost up to the Lake of Gennesaret consists of Cretaceous rocks chiefly of Senonian and Turonian age, with an occasional exposure of the underlying Cenomanian.
