International Series of Monographs in Electromagnetic Waves, Volume 11: Electromagnetic Wave Theory, Part 1 covers the proceedings of an International Scientific Radio Union (U.R.S.I.) Symposium on Electromagnetic Wave Theory. The book contains 61 chapters that are organized into three sections. The first section presents papers about wave propagation, which includes lateral waves; terrestrial waveguides; and plane waves in dissipative media. Next, the title reviews studies about wave guides, including basic properties of periodic waveguides; theoretical investigation of non-uniform waveguides; and waves in a coaxial line partially filled with plasma. The last section covers topics about surface waves, such as a dielectric prism in the corner of overmoded waveguide; lasers and optical communication systems; and microwave and laser resonators. The text will be of great use to researchers and practitioners of disciplines that study or utilize electromagnetic wave technologies, such as electrotechnics and electrical engineering.

Electromagnetic Wave Theory, Part 2 contains the proceedings of a Symposium on Electromagnetic Wave Theory held at Delft, The Netherlands in September 1965. The symposium provided a forum for discussing electromagnetic wave theory and tackled a wide range of topics, from propagation in nonlinear media to electromagnetic wave propagation and amplification in solid-state plasmas. Electromagnetic waves in nonlinear transmission lines with active parameters are also considered, along with the phase dependence of maser active material Q-factor on pump intensity and frequency. Comprised of four sections, this volume begins with an analysis of two modes of propagation that are coupled through parametric modulation in nonlinear media. The discussion then turns to symmetry restrictions in nonlinear, non-absorbing, non-dispersive media; nonlinear interaction between two beams of plane electromagnetic waves in an anisotropic medium; radiation in periodically non-stationary media; and electromagnetic wave propagation in time-varying media. Subsequent chapters explore the diffraction of electromagnetic waves by plasma structures; resonant electromagnetic scattering from gyrotropic plasmas; scattering and transmission of electromagnetic waves at a statistically rough boundary between two dielectric media; and developments in wavefront reconstruction. This book will be useful for students, practitioners, and researchers in physics.

Dr. Raymond Pederson, Dr. Jill Dryburgh and I commenced work on GIP in 1968, when, with the generous help of Professor Viktor Mutt and Professor Erik Jorpes of the Karolinska Inst,itute, Stockholm, we were able to establish that there existed an inhibitory material for acid secretion in cholecystokinin-pancreozymin prepara­ tions. Once the physiological evidence for the inhibitor was established it seemed appropriate to seek help in its isolation. Dr. J. Dryburgh and Dr. R. Pederson were left to bioassay fractions in Vancouver whilst I enjoyed the company of Professor Mutt at the Karolinska for one year, as a Medical Research Council of Canada Visiting Scientist. Purification of the inhibitory factor proceeded rapidly due, in no small measure, to Professor Mutt''s untirmg efforts on my behalf. Later that year, Dr. Dryburgh joined us in Stockholm to begin the sequence work on GIP. This was completed late in 1970 in Vancouver. In Stockholm in June 1970, I met a fellow Canadian Dr. John Dupre (McGill University) at a cocktail party who kept commenting about the possibility of GIP being an insulinotropic hormone, the "incretin" of earlier days. At that time, gastrointestinal physiologist as I was, I did not recognize the importance of his comment. This became apparent two or three years later when Dr. Dupre demonstrated that GIP was insulinotropic in man. In 1972, Maryanne Kuzio and Dr.
