“Rocks of augitic trap are found in various positions on it; the general strike is north and south; but when the gneiss was first seen, near to the basalt of the falls, it was easterly and westerly, and the dip toward the north, as if the eruptive force of the basalt had placed it in that position.”
“Pumice and trachyte are the most common rocks around this mountain, and these are augitic or porphyroid.”
“The sandstone rests on lava, is covered by a great bed apparently about 1,000 feet thick of black augitic lava, and over this there are at least 5 grand alternations of such rocks and aqueous sedimentary deposits, amounting in thickness to several thousand feet.”
“The molten trap broke through at various times, and presenting various appearances, but in nearly the same centre; here existing as an augitic rock, there as a syenite, yonder as a basalt or amygdaloid.”
“It forms the opening of a dreary moorland valley, bounded on one of its sides, to the mouth of the loch, by a homely ridge of Old Red Sandstone, and on the other by a line of dark augitic hills, that attain, at the distance of about a mile from the sea, an elevation of two thousand feet.”

“The character of rocks, as we have already remarked is so independent of geographical relations of space, * that the geologist recognizes with surprise, alike to the north or the south of the equator, in the remotest and most dissimilar zones, the familiar aspect, and the repetition of even the most minute characteristics in the periodic stratification of the silurian strata, and in the effects of contact with augitic masses of eruption.”
“The diamonds that occur furthest to the north, as those discovered in 1829 at 58 degrees lat., on the European slope of the Uralian Mountains, bear a geognostic relation to the black carboniferous dolomite of Adolffskoi* and to augitic porphyry, although more accurate observations are required in order fully to elucidate this subject.”
“Thus i have found angular fragments of feldspathic syenite imbedded in the black augitic lava of the volcano of”
