M. de Saussure has carefully examined those same objects; and he seems
inclined to think that they must have been the operation of the ocean;
not in the common manner of depositing strata, but in some other way by
crystallization. The present theory supposes all those masses formed
originally in the ordinary manner, by the deposits or subsidence
of materials transported in the waters, and that those strata were
afterwards changed by operations proper to the mineral regions.
But the subject of the present investigation goes farther, by inquiring
if, in the operations of the globe, a primary and secondary class of
bodies may be distinguished, so far as the one may have undergone the
operations of the globe, or the vicissitudes of sea and land, oftener
than the other, consequently must be anterior to the later productions
both in time and operation, although the original of all those bodies
be the same, and the operations of the earth, so far as we see in the
effects, always proceed upon the same principles. This is an extensive
view of nature to which few have turned their thoughts. But this is
a subject to which the observations described by this author have
evidently a reference.
In his 113th letter, he has given us a view of one of those parts of the
earth that are proper to be examined in determining this question so
important in the genealogy of land, although no ways concerned in
altering the principles upon which nature in forming continents must
proceed.
It is in describing the nature of the mountains about _Elbingerode_; and
he begins in ascending from Hefeld.
"Cette partie extérieure de la chaîne est _primordiale_: c'est du
_granit_ à _Hereld_ et au commencement de la route; puis quand on passe
dans d'autres vallées, on trouve les _schistes_ et la _roche grise_ dans
tout le pied des montagnes: mais des qu'on est arrivé à une certain
hauteur, on voit de la _pierre à chaux_ par couches étendue sur ces
matières; et c'est elle qui forme le sommet de ces mêmes montagnes;
tellement que la plaine élevée, qui conduit à _Elbingerode_, est
entièrement de _pierre à chaux_, excepté dans sa partie la plus haute ou
cette pierre est recouverte des mêmes _grès_ et sables _vitrescibles_
qui sont sur le schiste du Bruchberg et sur la _pierre à chaux_ dans la
_Hesse_ et le pays de Gottingue.
"Les environs d'Elbingerode étant plus bas que ces parties recouvertes
de matières vitrescibles, montrent la _pierre à chaux_ à nud; et l'on y
trouve de très beaux marbres, dont les nuances jaunes, rouges et vertes
sont souvent très vives, et embellies par les coupes des _corps marins_.
"Cependant le schiste n'est pas enseveli partout sous ces dépôts de la
mer; on le retrouve en quelques endroits, et même avec de _filons_.
