for it might well happen that strata which had subsided some miles nearer to the centre of the earth, and which had been pressed on by an enormous weight of superincumbent water, might have undergone far more metamorphic action than strata which have always remained nearer to the surface.
izan ere, gerta zitekeen, lurraren erdigunetik milia batzuk hurbilagora jaitsi eta beren gaineko uraren presio eskergaren pean izaniko estratuak, eragin metamorfiko handiagoa jasan izana, beti azaletik hurbilago izaniko estratuak baino.
