We saw there a nearly level terrace, 15^^ feet wide, its upper 

 bank inclining at an angle of 33° and its lower at 39°. For 

 half the width of this lynchet the goniometer stood at zero, and 

 then, passing outwards, at 6°, and finally at 9°. The surface of 

 the underlying hard chalk was for two-thirds of the width like- 

 wise level, and beyond had a slope of only 3°. Upon this lay 

 humus 13 inches thick at a, the inner border, and, gradually 

 diminishing, only 5 inches thick at 5, the outer border. This 

 lynchet, therefore, though it is so nearly level, agrees with that 

 on Warren Hill in having no accumulation, but a reduction of 

 humus towards its lower edge, and, similarly, it answers none of 

 the theoretical requirements of artificial origin.

 Diagram K is a sketch of the localitv.
