This book provides an excellent illustration of the interrelationship between progress in scientific methodology and conceptual advances, and its publica- tion should contribute to further advances. It is well known that major advances in understanding often follow the development of new methods. The development of the acetylene reduction assay for nitrogenase activity provides a good example of this interrelationship between theory and methods. Theoretical knowledge led to a search for substrates for nitro- genase that could be assayed for more easily than ammonium, the normal product of the...
