190 ON THE REVOLUTIONS 



large features of dressing very distinctly ; the scoopings, in 

 particular, are very well defined ; the small features have been 

 mostly defaced by the action of the air, but the removal of the 

 turf has brought some of them very well into view. These 

 agree with the grooves in the general indication of west 10° 

 south. In several places where a rent has occurred in the di- 

 rection of the stream, it has been excavated into the form of a 

 waving groove, as already seen in No. 5. 



No. 11. At the summit, a signal post had once been placed, 

 and the house used for that purpose, remains in a state of ruin *. 

 The rock of the summit (eight feet south-east from the south- 

 east corner of the house) is dressed with some diluvian furrows, 

 denoting west 10° south, as I found by clearing away some of 

 the turf. 



The ridge of the hill stretching to the south, shews every- 

 where the same general character, by the rounding of angles, 

 denoting the action from the west. 



No. 12. In a field called the South Mid-hill-park, in the 

 farm of Mid Clermiston, in the south-east corner of the field, 

 is a fine specimen, indicating west 5° south. 



No. 13. The rock on which the summer-house of Ravelstone 

 stands (the Stone View, as it is called by the country people) 

 though completely exposed to the weather, shews some de- 

 cided furrows. It forms the summit of the southern part of 

 the ridge, and is only a few feet lower than the highest 

 point. From it the scenes No. 1. No. 3. and No. 4. are still 

 distinctly visible. 



No. 14. In a pasture-field facing to the south, called the 

 Sheep Park, belonging to Corstorphine Hill house, and imme- 

 diately 



* Since this paper was read, the signal-house has been removed, and its foun- 

 dation only is now visible.
