leaves also suggest. | 
Between the coral-locality and Helmsdale very little is to be seen ; 
but on the other side of the town, as noted by Prof. Judd, the 
breccia-beds predominate, and there is little room left for ordinary 
strata. Such shales as appear owe their position and apparent 
contortion, in most cases at least, to the pressure of the stones in

the breccia. On this account it is difficult to be certain of any 
direction of dip, or strike, in the beds. They do not, in fact, appear 
to have any orientation or arrangement at all, nor is any evidence 
of contortion possible in such deposits (fig. 7, above). 
On turning the corner, however, into Navidale, fresh phenomena 
appear which are certainly very instructive. In the first place, 
though the breccias themselves are as rough as ever, there is some 
method in their roughness, one side being more scarped than 
the other, and the crests run somewhat parallel to cach other.
