Note 37 — Chapter IX

“The whole formation of the mountain (Büdös) and the surrounding cones, the sharp-edged blocks and masses of rock, heaped up one on the other, of which these consist, the apparently molten surface of the trachyte—all seems plainly to prove that it was only after the formation of these masses, and when they were in a rigid state, that a grand upheaval took place here; during which, the powerful gases from below, raising, and straining, and tearing the masses, piled them up in mighty domes and mountain-tops, tossing them about till, here and there, they had found permanent canals leading to the surface of the earth.” (Frederic Fronius, quoted by Mr Bonar).
