For those who are interested in the intellectual development of the ideas of Georges Cuvier, this volume will go a long way to satisfy that interest. The editor has arranged all Cuvier's published source material in a series of both convenient as well as documentary "stages" that will aid the researcher in looking up published bibliographic references. The book is organized along the following types of documentation: Journals (records I-S6,6) Annual Review of Science (records S67-6S2), monographs (records 653-823), Contributions to Encyclopedias (records 824-908). The volume contains a chronology of Cuvier's life, a forward by Stephen Jay GeuId, random statistical notes, a personal name index, and a subject index. The volume is extremely well organized and it is easy to use. The editor has done a fine job of pulling together the Cuvier's published materials from disparate sources. The researcher interested in Cuvier's work will find this volume indispensible.
