To an earlier and longer epoch belongs the Prepalolithic or eolithic stage.
To the east is the plateau of Kent, in which many flints of eolithic type have been found.
The eolithic problem has aroused the most animated controversy, in which opinion is divided.
In the last place will be mentioned criticism of the distribution of the eolithic type (Obermaier, 1908).
The distribution of the implements finds a weak spot in the defences of the eolithic partisans.
