3. Remarks on certain grooved surfaces of Rock on Arthur's 

 Seat. By the Rev. Dr Fleming. 

 Dr Fleming read a paper, entitled " Remarks on certain grooved 

 surfaces of Rock in Arthur's Seat." He referred, in the first in- 

 stance, to the surface of the bed of porphyry, known as the Bog 

 Crag, and contiguous to the Hunter's Bog ; and shewed, from the 

 directions of the markings being neither parallel to the valley, nor 

 the neighbouring cliff, that they could not be the result of glacial, 

 diluvial, or iceberg action, but were probably caused by the sliding 

 of the contiguous beds at their upheaval ; and this view he consi- 

 dered strengthened by the state of the detritus of the cliff of the 

 Well Crag. He then took notice of a grooved surface of basalt, con- 

 tiguous to a singular trough to the east of St Anthony's Well, 

 but which might have been produced either by glacial or dUuvial 

 action.
