The same views were maintained by Professor Mojsisovics in his "Dolomit-riffe von Sudtirol und Venetien," which appeared in 1879. The first serious note of dissent to the generally accepted theory was heard in 1863, when a distinguished German naturalist, Dr. Karl Semper, declared that his study of the pelew Islands showed that uninterrupted subsidence could not have been going on in that region.

But while making this admission, he firmly maintained that exceptional cases, like those described in the pelew Islands, were not sufficient to invalidate the theory of subsidence as applied to the widely spread atolls, encircling reefs, and barrier-reefs of the Pacific and Indian Oceans.

It is known that now and then single canoes from the pelew or the Ladrone Islands were driven upon the east coast of Luzon, but their importance ought not to be overestimated.
