Although, as already noticed, these fossils are certainly derived 

 from transported masses (the only rock of Jurassic age certainly in 

 situ on the south side of the Moray Firth being that already de- 

 scribed as occurring at Stotfield), yet it must be remembered that 

 over very large areas the rocks are totally concealed by drifts ; and, 

 as we have seen that they are traversed by a number of faults of 

 great magnitude, it is possible that these fragments with Jurassic 

 fossils, so abundant in the Elginshire drifts, are not far distant from 

 their parent rocks, which may, indeed, in places, underlie the vast 

 masses of Boulder-clay which mask the country. 



§ 5. The Upper Lias. 



At this horizon we have an unfortunate gap, the only complete 

 one, in the series of beautiful sections of the Jurassic strata in 

 Sutherland. It is quite possible that the very thick series of es- 

 tuarine strata (sandstones, shales, and coals) which underlies the 

 Middle Oolites of this district, may represent both the Lower Oolites 

 and the Upper Lias also. That the latter era in the east of Scot-
