northward at high angles, the apex sinking westward as in the former 

 case, and the southern side apparently sharply reflected upon itself, so as 

 to bring the red-clays of the red-zone into view beneath the limestone 

 both within and outside its southern limb. The gypsum band in the 

 centre is very narrow, the red clays more largely exposed, the nummuli- 

 tic limestone thinner than usual, containing the usual fossils, and the 

 tertiary sandstone series with a conspicuous red clay band below sweeps 

 round from the northern side, over-rolling and continuing the expres- 

 sion of the anticlinal in finely marked curves to the westward.

nummulitic limestone containing thick nummulites and other fossils pro- 

 ject, or overlie apparently the newer sandy clay series. This limestone 

 may have a thickness of over 100 feet, and is succeeded apparently by 

 some of the lower tertiary purple and greenish sandstones and red clays, 

 near which another crag of limestone without any visible relation 

 appears. In another place the newer tertiary soft beds seem to form 

 a dome-shaped mass surrounded by an imperfect ring of the shaly 

 nummulitic limestone, the debris of which dresses all the hills in the 

 neighbourhood, giving the ground a dirty orange colour and smooth 

 barren look. 



The soft, coarse, gray sandstones and brown clays of the upper 

 tertiary series are much disturbed, very fragile, and

sometimes contain thin veins of heavy spar and 

 occasionally also conglomeratic layers, the pebbles in which are formed of 

 granitoid or other crystalline rocks, with an odd one here and there of 

 alveolina limestone, showing that the strange conditions which enabled 

 these latter to be transferred from the place of their formation without 

 any appearance of unconformity between the two groups extended 

 throughout nearly the whole of the newer series. Fig. 41 is a
