This volume brings together contributions by leading researchers covering a wide scope so characteristic of fluorine chemistry. It is a monograph of historical character comprising personalized accounts of progress and events in areas of particular interest. There is also much to interest and instruct chemists from other disciplines as a good proportion of the chapters contain a considerable amount of 'hard' referenced information relating to modern organic, organoelemental and inorganic chemistry. Historians of chemistry and technology will no doubt be tempted to dip into this book, and surely whoever addresses the task of commemorating Moissan's achievement at the 150-years stage will bless us all in some measure for its existence.
