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 greywacke 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. 
Newminys, 26th August, 1899.—On the afternoon of this date 
Mr. Andrew Gilchrist conducted a very small party to Lanfine 
Estate, near Newmilns. The estate is finely situated, and is 
extensively planted with a great variety of ornamental trees and 
shrubs. Among native plants seen may be mentioned Impatiens 
Noli-tangere, Linn., Epipactis latifolia, Auct., Carex pendula, 
Huds.
