Contents: Part A, The Basis of Scenery: The Behavior of the Earth's Crust; I. The Structure of the Earth's Crust; II. The Unity of Gondwanaland During the Late-Paleozoic and Mesozoic Eras; III. Continental Structure: (A) Shields; IV. Continental Structure: (B) Mobile Welts; Part B, The Development of Continental Scenery: Degradation and Aggradation: V. The Standard Cycle of Denudation; VI.

The Atlantic, Arctic, and Indian Oceanic Basins; XVIII. The Pacific Basin; Part F, Review; XIX. Towards a Model of the Earth; Selected Bibliography; Index. The evolution of the Earth's surface is studied by classification of landscape features and comparison of these from continent to continent. The author interprets the morphology of the Earth in terms of a standard set of current cyclic denudations from Mesozoic until recent times, using the most stable continent, Africa, as the type for morphological development.
B-22. The Planet Saturn, A History of Observation, Theory and Discovery, A. F. O'D ALEXANDER,MacMillan, N. Y., 1962. 474 pp. $12.00. This descriptive summary includes historical observations to the present. It is well-written, of interest to both layman and astronomer. An Appendix gives the opposition of Saturn from 1956 to 2000 and a section on observing Saturn. The author is director of the British A~tronomical Association Section on Saturn.
