The prodomus of Nieolaus Steno's dissertation con- cerning a solid body. Contributions to the history of geology. Volume 4. EmrED BY GEORGE W. WroTE. Pp. vii+ll5. New York: Hafner, 1968. Price $ 12.50. This edition of a geological classic first published in 1669 will appeal to crystallographers with a historical bent primarily for its discussion on the shapes of crystals. The author had noticed that although crystals of a particular material (e.g. quartz or haematite) came in a great variety of shapes and sizes, the same interracial angles recurred in every specimen. He went on to discuss the growth of crys- tal;
