Abstract
ON the surface of contact of two different media, such as air and water or water and sand, various rhythmic forms are produced when there is relative movement. The forms vary widely in kind and order of magnitude, and include sand dunes, ripple-marks, and river meanders. This book is devoted to a systematic account of the phenomena involved and the morphological features produced, and is useful as a compilation of observations and hypotheses, and as a bibliography of the subject. Unfortunately the physical treatment is weak and no mathematical discussion is presented. Although the book does not add any original contribution to the theoretical aspects of the rhythmic and periodic phenomena of geology, it will nevertheless serve a valuable purpose in providing geologists, geographers, and engineers with a most convenient summary of what is already known in a somewhat neglected field of investigation. The author deserves our gratitude, if only for his enterprise in tidying up a very scattered subject.
