 ... bear at least a very striking analogy. Points on one side are frequently represented by hollows on the other, and even complicated figures occasionally find a counterpart, the configuration being always relatively convex or concave. This would seem to indicate very clearly that the mass had been forcibly rent asunder, either by the contractile process of heat, or a convulsion of the earth. The most difficult point to determine is why the bottom should be so flat and ...
