The four preceding papers are in many respects models of presentation. They exemplify the process method applied to _regions_, a phase of much importance in certain ecologic studies, particularly ecological surveys. The last two papers are rather detailed applications of the same ideas. A very profitable study may be made of the method of presentation in these papers. DEVINNE, T. L. 1902.
