II. — jS'ote on a Hypersthene Andesite from Pitctjllo, Fifeshire. 



By D. Balsillie, F.G.S., Chemistry Department, University of Edinburgh. 

 rnWENTY-ONE years ago Dr. Flett in a valuable paper (Trans. 



j_ Edin. Geol. Soc, vol. vii, 1897) described an exceedingly 

 beautiful hypersthene andesite from the volcanic series of the Lower 

 Old Red Sandstone at Dumyat in the Western Ochils. In the 

 following brief communication I propose to give a short petrographic 

 account of a strikingly similar rock that has occurred to me in the 

 field in a more easterly portion of the same range of hills and which 

 is of the same geological age. 



In East Fife the volcanic rocks of the Lower Old Eed Sandstone 

 rise abruptly above the southern shores of the Firth of Tay. They 

 consist here as elsewhere of lavas, tuffs, volcanic breccias, and 

 agglomerates, with intervening belts of sediment that no doubt
