Although the Middle Oolite strata have not heen found in situ on 

 the south side of the Moray Firth, yet fragments of them are remark- 

 ably abundant in the Boulder-clays of that area. In many places, 

 as in the bed of Loch Spynie, fragments of the coals, unfossiliferous 

 sandstones, &c. of this series abound, and in one case induced the 

 proprietor of the laud to undertake a boring in the hope of finding 

 a bed of coal. Fragments of the blue Oxfordian shales, crowded 

 with their characteristic fossils, are also abundant in the Till ; and 

 rounded waterworn masses of them are often picked up on the shore. 

 Such masses of Oxfordian beds with fossils have been found, some- 

 times mingled with fragments of other rocks, at a number of points in 

 Elginshire, at the brickyard of Blackpots, near Banff (where the re- 

 constructed clays are dug for brickmaking), and at the Plaidy cutting, 

 between Macduff and Turriff, in the county of Aberdeen. 



In the parish of Urquhart*, in the county of Elgin, there are 

 portions of the Boulder-clay almost made up of fragments of the 

 Oxfordian strata, crowded with the characteristic fossils. These 

 have been very carefully collected by the Rev. James Morrison ; and 

 from the specimens preserved in his private collection, and those 

 placed by him in the museums at Elgin and Marischal College,. 

 Aberdeen, I have been able to compile the following list :—
