figs. 10 and 11. The plan (fig. 9) shows the general relations of
the strata exposed in Eathie Bay. At one point the rocks of the
Upper Oolite, near their junction with the Old Red Sandstone, present
the same crushed appearance that is so common, under similar
circumstances, with the strata in Sutherland.
Crossing to the south side of the Moray Firth we find at Stotfield,
in the county of Elgin, a patch of sandstone strata, to which my at-
tention was first called by Dr. Gordon, and which has yielded to the
patient researches of Mr. Grant, of Lossiemouth, a very considerable
fauna. These beds, as will be shown in the sequel, are of Lower-
Oolite age ; and they are clearly seen to be faulted against the strata
composed of calcareous and arenaceous rocks of Triassic age (see
section fig. 12) *. It is possible that the whole of the reefs at this

point, and of the outlying rocks called Halliman Scars, are of the
same age, and that their red colour is an accident due to similar
causes to that which has produced the red colour of many of the
reefs of Oolitic rock on the shore of Sutherland. These beds,
however, have as yet yielded no fossils ; and future researches may
show that they are of a different age, and have been brought into
their present position by another fault.
The promontory of Burghead is formed by a series of sandstones,
grits, and conglomerates which, as Professor Harkness has well
shown, is faulted against the great mass of the Reptiliferous sand-
stone f which forms the coast-ridge here. The similarity of position

• Since this paper was read, Prof. Ramsay has kindly intrusted to me the
  

note-hook used by him during his examination of the north of Scotland in 1859.
It affords me no small satisfaction to find that in this, as in a number of other
points, my own conclusions are entirely confirmed by the unpublished observa-
tions of my former teacher. Prof. Ramsay recognized the existence of a great
fault at Stotfield, and represented it in a section identical in all essential points
with my own.
