vertical situation; and
it is in these inclined strata that geologists allege that there is not
to be found any vestige of organised body. This opinion, however, I have
now proved to be erroneous.
There cannot be any doubt with regard to the original formation of those
stratified bodies, as having been formed of the materials that are
natural to this earth, viz. the detritus of former bodies; and as having
been deposited in water, like the horizontal strata: For the substances
and bodies of which they are visibly composed are no other than those
which form the most regular horizontal strata, and which are continually
traveling, or transported at the bottom of the sea, such as gravel, and
sand, argillaceous and micaceous bodies.
On each side of this ridge of mountains, which towards the east end is
but narrow, there is a lower country composed of strata in general more
horizontal; and among which strata, besides coal, there are also found
the relics of organised bodies.
Abstracting at present from any consideration of organised bodies among
the materials of those strata, it may be affirmed, that the materials
which form the strata in the mountains and in the low country, are
similar, or of the same nature; that they have, in both places, been
consolidated by the same means, viz. heat and fusion; and that the same
or similar accidents have happened to them, such as change from their
original position, and mineral veins traversing them in various shapes.
Yet still there is a distinctive character for those two bodies, the
alpine and the horizontal strata; for, while the horizontal position
appears natural to the one, and the changes from that particular state
to be only an accident, the vertical position appears to be more natural
to the other, which is seldom found horizontal.
Therefore, altho' it is unquestionable that the strata in the alpine and
low countries had the same or a similar original, yet, as the vertical
position, which is the greatest possible change in that respect, is more
natural to the alpine strata, or only necessary in the natural order of
those bodies, we are to consider this great disorder or change from the
natural state of their original formation, as the proper character of
those alpine strata. But then it is also necessary to include in this
character a general hardness and solidity in those vertical strata,
otherwise they would not have been properly alpine, or have resisted the
wearing
