Accurate soundings are as yet much too distant 
to justify anything like a detailed contour map of the

correct. 
According to our present information, we must_ 
regard the Atlantic Ocean as covering a vast region 
of wide shallow valleys and undulating plains, with 
a few groups of volcanic mountains, insignificant 
both in height and extent, when we consider the 
enormous area of the ocean bed.
