THE GEOLOGIST. 



Firth of Beauly/Muckairn, in the neighbourhood of Inverarj^, 

 at Dunkeld^ and near Creekhope Linn, in a valley in Dum- 

 frieshire. Both Dr. Buckland and Mons. Agassiz observed 

 scored and striated surfaces on the Calton Hill, the Black- 

 ford Hill near Edinburgh, and on the left flank of the vale, 

 called the Braes of Foss. 



Mr. J. E. Bowman, in a paper read before the Manches- 

 ter Geological Society, traces their existence on the Eildon 

 Hills, and Mr. Lyell has observed other occurrences, con- 

 clusive to himself on this point, near Penrith. 



Although a subject of dispute, we will venture to give our 

 opinion, that the evidences afforded in many instances are 

 satisfactory, not, however, in establishing general centres of 

 glacial action, but tending to prove that they were numerous 

 and distinct. 



The observations of Agassiz and others, on the subject of 

 the formation and action of glaciers, are more clear and better 

 substantiated, and we have endeavoured to present these in 

 an intelligible form, with the true sense of the respective 

 authors from whom we have collected the information. 



We have added a lithographic view of the glaciers of the 

 Finsteraar and Lauteraar, adapted from that given by M. 

 Agassiz, in order to exhibit the nature and effects of 

 glaciers.
