Thus on Wollaston Island slate and grauwacke can be distinctly traced passing into feldspathic rocks and greenstones, including iron pyrites and epidote, but still retaining traces of cleavage with the usual strike and dip. One such metamorphosed mass was traversed by large vein-like masses of a beautiful mixture (as ascertained by Professor Miller) of green epidote, garnets, and white ...

Now if the space alluded to between the nucleus and the impression, instead of being left empty, has been filled up with calcareous spar, flint, pyrites, or other mineral, we then obtain from the mould an exact cast both of the external and internal form of the original shell. In this manner silicified casts of shells have been formed; and if the mud or sand of the nucleus happen to be incoherent, or soluble in acid, we can then procure ...

The engineers furnished me with a register of the strata so far pierced by the bore, but, as they are not described in the technical terms of geology, it is rather difficult to compare them with those of the old well. At a depth of 490 feet, sandstone with iron pyrites was pierced; this would probably be the ferruginous Northampton sand of the Oolite. It is at a less depth than the same stratum at the Spa well; but that was to be expected, as geologists state that all the geological strata “dip” eastward, and this bore being to ...
