Cup and Ring Stones

Abstract

MANY of the markings mentioned by Mr. Middleton are hollows made by rain, or rather deepened by rain-water holding many low organisms in hollows, on the upper surfaces of exposed grit stones; overflow from these accounts for the groove or spout noticed at the margin of some of them. They are to be seen on the stones erected near Boroughbridge, and speak to the length of time these stones must have been raised into their present position.
