the Cretaceous limestones. Three-fourths of this, comprising- the 
beds, form a toj inclusive, represent the middle and lower chalks of 
Palestine, not necessarily corresponding with the middle and lower 
chalk of England, but about that horizon. There are beds of hard 
and soft alternations, containing a recognized and tolerably abundant 
fauna. 
In western Palestine these middle and lower beds are for the 
most part seen, as here, in the gorges, though sometimes pei'haps 
brought to the surface of the plateau by synclinal folds. These are 
the beds which it has so often been the fashion to speak of as Neo- 
comian and Jurassic, but whose very lowest horizon contains a fauna 
which M. Lartet regards as Cenomanian. The gorge of the Wady 
Mo jib also shows a fine section of the upper white chalk- with-llints,
