Abstract
On the eastern side of Barnavave, at the immediate junction of the igneous mass with the surrounding limestone and about a quarter of a mile south of the fault which crosses the mountain, there is an isolated outcrop of a fine-grained, speckled rock which clearly invades the limestone at this point. The rock includes xenoliths broken from the limestone and also others of igneous origin.-and smaller dimensions. Microscopical examination proves the rock to be a syenite of unusual character which carries a small amount of quartz. It is possibly the rock referred to by Harker.
