confirmation of our assumption regarding the nature of the sima in the absence of such uprising folded ranges in the ocean floor. These masses are certainly folded. If they had consisted of sial, the folding would, at least partly, have been directed upwards and come into view. These circumstances will become still clearer by the considerations mentioned in Chapter IX.
The proofs given in this chapter of the nature of the floor of the ocean speak in a very clear and impressive language. Hence this aspect of our theory has up to the present encountered least opposition, and these ideas have been accepted by most geophysicists.
