all of this character, intercalated here and there with bands of 

 limestone which has also undergone severe metamorphism, render- 

 ing it schistose. This metamorphosed limestone is even more 

 folded and contorted than the other schists. Near the Bull Rock 

 the grey wacke is quarried for building purposes. In many places 

 the schists are cut through by basalt dykes running in a N.N.W. 

 direction. The geological map shows that these dykes run up 

 against a broad east-and-west dyke, coloured dark crimson. The 

 Castle Hill, Dunoon, is at one end of this broad dyke. From this 

 point it crosses the country to Loch Striven and Loch Fyne. The 

 Geological Survey has shown this broad dyke to be older than the 

 small dykes, as the latter intersect it at places, but the age and 

 superposition of the schists, except that they are certainly not 

 later than Silurian, are not determined. Mr. Joseph Sommerville, 

 Vice-President, acted as conductor.
