Introduction From time to time scattered allusions to geographic, physiographic, and geologic influences in the Philippine Islands have appeared in the writings of Quatrefages, Gannett, Ratzel, Semple, and others, among whom the writer is included; but so far as the writer is aware no article has appeared which is devoted entirely to this most interesting field of research.
