Despite the fact that Brodie's chemical calculus proved unfruitful in the development of chemistry, this study is a worthy one for i t helps to reveal the true nature of science. All too often students gain the impression that science is a glorious series of success stories. Occasionally looking a t the failures helps to reveal the way in which understanding of science really develops. This study shows Brodie not to be a fool hut quite sound in the position he espoused at the time.

Seldom is a project a worthy subject for a biography. The magnitude of the CHEM Study effort would almost he a sufficientlyvalid reason for miting such a book. The subseqnent effect of the program on secondary education confirms the value of this record of how the project was accomplished. It is an "inside" story, hut told with candor and restraint. Though some may object to the number of times the adjective "enthusiastic" appears, any who were involved know how truly it can be applied. The reader will find both anecdotes and facts. Almost half the volume is devoted to appendixes, much of it tabular information. The many individuals who contributed portions of their professional lives to the creation of CHEM Study will be eager readers. Any who contemplate a participation in a similar curriculum revision ought to he.
