Dr. J.T. Edward is recommended for Fellowship in the Royal Society of Canada with confidence because of his proven ability, and with enthusiasm because of his attractive personality. His publications are primarily concerned with natural products, but also clearly reveal his great interest in modern theory and technique. This experience, including alkaloids, terpenes, nitrogeneous products and carbohydrates, and contributions to conformational analysis, chromatography, and electrophoresis, shows him to be one of' the most versatile, productive and original chemists in his age group.

George Elliott has made important contributions to operator algebras. His work on derivations and his discovery of the significance of K-theory for AF-algebras have been the basis for work by leading mathematicians all over the world. Akemann and Pedersen's characterization of the separable C*-algebras for which all derivations are inner, stated 'We have borrowed freely from the ideas of G.A. Elliott '. In AF-algebras, a chaotic situation was completely changed by Elliott's discovery that with natural ordering, the group Ko has the Riesz separation property and is a complete invariant for the AF-algebra.

Sam Epstein is the father of stable-isotope geochemistry. In the early 1950s, he developed the carbonate isotopic paleotemperature scale, a discovery that had a monumental impact on the Earth Sciences. Moreover, his work from this period is the foundation stone on which all future developments in light stable-isotope geochemistry are based. Throughout his career, Sam has shown remarkable scientific insight into the application of stable-isotope geochemistry to an incredible diverse set of problems in Earth and biological sciences, and has continued to make seminal contributions down to the present time.

In recognition of a long and illustrious career in academic medicine in Canada, and internationally. As its first dean, Dr. Evans was personally responsible for the development of a highly innovative medical school at McMaster University. He was instrumental in identifying the importance of epidemiology and biostatistics in that school and elsewhere in Canada. In addition to these initiatives Dr. Evans has played a central role in academia in Canada and has acted as advisor to numerous bodies throughout the world, including the World Bank.

Professor George T. Ewan is internationally known for his studies of nuclear spectroscopy made at the Chalk River Nuclear Laboratories. His investigations in beta-particle and gamma-ray spectroscopy have made use of high resolution spectrometers, towards the development of which he has contributed greatly. For his development of the germanium (lithium-drifted) detector as a gamma-ray spectrometer he shared the Radiation Industry Award of the American Nuclear Society in 1967. Responding to invitations he has written definitive review articles on Internal Conversion Processes and on Semiconductor Spectrometers. More recently, he has combined his high resolution techniques with charged-particle accelerators to extend his studies of the properties of nuclear states.

A. Murray Fallis, B.A., Ph.D., is concerned chiefly with the taxonomy, life history, and pathological effects of parasites. As Professor of Parasitology at the University of Toronto, he is in charge of the training of both graduate and undergraduate students in parasitology. In both capacities Dr. Fallis has made and is making very significant contributions in this important field of biology. In many scientific publications he has reported the results of his researches on a wide variety of parasitic animals. Among these, his work on blood parasites has been outstanding. Dr. Fallis is now on an expedition in Central America and could not be reached in time for this meeting. I therefore move that he be received in 'absentia'.

David Farmer, Adjunct Professor, University of Victoria and The University of British Columbia, and Research Scientist, Institute of Ocean Sciences, is Canada's leading civilian underwater acoustics expert and is one of the best known, and most widely respected, in the world. He has used underwater acoustic systems in a wide variety of imaginative ways, taking advantage of the only form of remote sensing effective for most of the ocean. His studies have been very wide ranging, including flow in fjords and straits, studies of ocean turbulence, wave breaking and flow under ice. Dr. Farmer's ingenious techniques and imaginative interpretation have made him a leader in each field he has touched.

Ronald McCunn Farquhar has used his skills in isotopic studies and mass spectrometry to determine the ages of Canadian minerals and geological provinces and to interpret variations in lead isotopes in geological terms. This work has been marked by originality and imagination. Originally graduating in physics and chemistry, he has steadily increased his knowledge of geology by field work and close cooperation with the departments of geology. He has been secretary of the Committee of the Royal Society of Canada on Precambrian Dating and he is engaged in placing all published age data for the whole world on punched cards for data processing. To his impressive list of 26 articles and one book will soon be added a second book on geochronology by isotopic methods which he and Prof. D. York have largely completed. His merit has been recognized by the award in 1954 of a National Research Council Post-Doctorate Fellowship and in 1964 of a Royal Society of Canada Fellowship which enabled him to work for 9 months with Prof. L. R. Wager in the Department of Geology at Oxford.

Dr. Feldman, Department of Mathematics, The University of British Columbia, has made many deep and significant contributions to mathematical quantum field theory; for example, the construction and analysis of the [phi]4/3 model, sharp bounds on general Feynman graphs, and analysis of singularities in the complex Borel plane for [phi]4 theories, and a proof of renormalizability of QED4. With Magnen, Rivasseau and Sénéor, he constructed the (non-superrenormalizable) infrared [phi]4/4 and Gross-Neveu_ models, by developing powerful new techniques (phase space expansions) theories. He has become one of the world's leading field theorists.

Robert Bury Ferguson, Professor of Geology at the University of Manitoba, was born in Galt, Ontario, and received his education there and at the University of Toronto. He joined the staff of the University of Manitoba in 1947, and except for a year as a post-doctoral fellow at Cambridge, has been there ever since. He started as a general geologist with experience on field parties in his student days but gradually shifted to mineralogy. His researches have been on a variety of mineralogical problems such as red gold, titanium compounds, the morphology of muscovite, and the crystallography of synthetic YTa04. More recently, he has become widely known for his work on feldspars.
