YI. The Igneous Eocks of Grange Hill. 



The igneous rocks of Grange Hill form the summit of its whole 

 ridge, and extend for nearly a mile in a north-east-and-south-westerly 

 direction. An ash-bed, generally light green in colour, but weather- 

 ing brown, is exposed frequently along the north-western slope of the 

 hill, and behind Grange Hill House Cottage has yielded abundant 

 organic remains. The beds immediately beneath and above this ash- 

 bed are exposed at a very few places. Close to Grange Hill House 

 there occurs immediately beneath the ash-bed a very vesicular light 

 green andesite, the vesicles being filled mainly with a dark green 

 mineral. A section of the rock shows a groundmass almost entirely
