"A ce _filon_, s'en joignent d'autres plus embarrassans. Ils viennent du _toit_, qu'ils divisent par de larges _fentes_ comblées, aboutissantes au _filon_ principale. Ils font de même _calcaires_ et marins faits par _couches_; mais ces _couches_ ont une si grande inclinaison, que je ne puis les comprendre: il faut qu'il y ait eu d'étranges bouleversemens dans ces endroits-là[27]. [Note 27: Here, no doubt, are appearances which it is impossible to explain by the theory of infiltration; it is the filling of mineral veins, and their branches or ramifications, with marble containing marks of marine objects. But, if we shall suppose this marble to have been in the fluid state of fusion, as well as the iron-ore and jasper, we may easily conceive it introduced into the principal vein and its branches. The description here given of those appearances is by no means such as to enable us to judge particularly of this case, which surely merits the most accurate investigation, and which, I doubt not, will give physical demonstration of the fusion of those mineral substances. I know that shells have been found within the body of veins in Germany; but, a stratification of those materials in a vein was never heard of before, so far as I know.] "Ces _fentes_ se sont faites, et ont été remplies, dans la _mer_; puisque les matières qui les remplissent sont de la classe de ses dépôts très connoissables, et qu'il contiennent des _dépouilles marines_. Mais ce qui embarrasse alors c'est que les autres _filons_ ne soyent pas dans le même cas. N'est ce point là encore un indice, que ces _fentes_ out été d'abord et principalement remplies de matières, poussées du fond par la même force qui secouoit les montagnes[28]. [Note 28: But what is this power by which matter is to be forced from the bottom of the sea to the top of the mountains? For, unless we can form some idea of that power which, as a cause, we ascribe to the perceived effect, we either say nothing to the purpose, or we employ a preternatural cause. It is not sufficient to imagine a power capable of raising from the bottom of the sea the materials deposited in the abyss; it is also necessary to find a power capable of softening bodies which are hard, and of thus consolidating those masses which are formed of loose or unconnected materials. Such a power, indeed, the present theory assumes; and, so far as this shall be implied in the supposition of our author, it will thus have received a certain conformation.]
