There are four parts to this volume - a chronology of events by year, a chronology of leading scientists grouped by the decade in which they reached 25 years of age? a research guide, and a research bibliography. The author has written extensively on American science, including co-editing the volume Science at Harvard University (reviewed in BHA 2(1):17-19).

The volume covers mostly what are termed the "hard" sciences (-.e., chemistry. biology, geology, etc.) and touches upon the social sciences only rarely. The chronology. that takes up two thirds of the book, extends from ca. 1493 to 1990 and includes only three archaeological events. An example of these entries follows:

"1877. ARCHAEOLOGY
Ephraim George Squier (1821-1888) published Peru: Incidents of
Travel and Exploration in the Land of the Incas (New York and London). Herelated his discovery of Latin American civilizations that predated the Inca. (p. 114)"

The scientist cohorts by decade also focuses upon the hard sciences, although three men are singled out from archaeology F. W. Putnam, N. H. Winchell, and T. M. Prodden - a peculiar sample of American archae­ologists indeed!
