The great curve bounded by New Guinea, the Philippines and Japan is an example of such a convexity in the Pacific. This method of geometrical construction shows that the crest of the " East Pacific " Rise (part of which is also known as the Easter Island Ridge) lies near the median line between New Zealand and Antarc-
