before, follows the broader outlines of the coast, the dip being 
always gently seaward. The included fragments here become larger 
and more abundant, one near Navidale being about the size of 
a fowl-house, and another at Greentable Point about twice as 
large. In both these cases we can see below them and be certain 
that they have been transported, and they indicate probably the

maximum force expended in the production of the breccia. In the. 
cliffs, up to 100 feet and more, are found some ferruginous sands. 
and sandstones, the age of which will be suggested later ; but their 
relations to the breccia-beds are obscure. The great fault here also 
affects the cliff-face, and breccias of granite are seen. No further 
light is thus thrown directly on the present enquiry, and beyond 
Greentable Point all that is seen is the straight line of the fault 
running northward towards the Ord, with the granite forming the 
_ cliff on the west, and the last relics of the breccia-beds forming a reef 
on the shore to the east. 
LY. Summary oF REsvtts. 
The results of the evidence thus adduced, in addition to the con- 
firmation of the six points hereinbefore mentioned as established by 
Prof. Judd, may be stated as follows :— 
(7) The floor on which the Jurassic rocks rest, when accompanied by breccia- 
beds, is at no great depth below the sea-level, nor was it at the time of their 
deposit. 
(8) It was diversified by sea-stacks, very much as the coast of Caithness, 
composed of the same ‘ Flags,’ is diversified at the present day by the Stacks of 
Duneansby. 
(9) The fragments contained in the breccias may have come, in some cases, 
from the cliff and stacks of their immediate neighbourhood, and in others from 
no great distance. 
(10) The breccia-beds are coterminous towards the south with the present 
exposure of the Caithness Flags, which throughout runs parallel to the shore 
on which they lie. 
(11) Their frequency is intermittent, increasing from south to north. None
