Bones, teeth of ox, sheep, and roebuck, and of 
some birds occur. Burned bones not unfrequently, 
and once a small bit of red earthenware occurred, 
but as yet no implements. 
Nothing appears in the situation or condition of

Mr. Sidebotham’s accidental absence was much regretted, as

and examined, as were also specimens from Grin Edge and
