TYRIE. 131 



two of the most conspicuous of these we shall conclude this 

 short account of the southern coast of Fife. The first ob- 

 ject of interest to be observed in proceeding along the coast, 

 is at a short distance to the east of the village of Kinghorn, 

 where a stratum of white sandstone is completely envelop- 

 ed in the greenstone. It varies in breadth in different 

 places, and in those parts which are thinnest becomes com- 

 pletely changed into quartz rock, while in the others there 

 is a gradual transition made from a quartz rock at the junc- 

 tion with the trap, to a sandstone, forming the more central 

 parts of the stratum. It exhibits a slightly undulating 

 position, and splits easily into irregularly-shaped masses, in 

 a direction more or less at right angles to the plane of the 

 bed. The other point where interesting phenomena are 

 displayed is at Tyrie Bleachfield, a point almost at the ex- 

 tremity of this series of rocks. Here a mass of greenstone, 

 presenting the ordinary character, occurs, and having the 

 same N. E. dip as the other rocks of the coast ; it rests in 

 one part on thin strata of black slaty sandstone, and in 

 another on a white sandstone. Lying immediately below 

 the white sandstone, and in contact with it, a vein of clay- 

 stone-felspar appears, identical with that of Whinny Brae 

 quarry ; it traverses strata of black slaty sandstone and 

 shale, and finally is seen to thin out between them and a 

 stratum of white sandstone, inferior to that upon which 

 the overlying greenstone mass rests. In its course, this 

 vein of felspar gives off minute veins, and is also shifted in 

 two places, a proof in addition to that which the Whinny 

 Brae quarry exhibits, that disturbing influences had ope- 

 rated after the eruption and consolidation of these igneous 

 rocks. Below the lowest series of black slaty sandstone 

 and shale strata, a bed of limestone occurs, resting on one
