Arthur Ferguson McKay, Vice-President, Research and Development, Monsanto Canada Limited, is an outstanding organic chemist. For his prolific work in the field of organic nitrogen derivatives he has won international recognition. A native of Nova Scotia, with degrees form McGill, Dalhousie, and Toronto, he held appointments at Queen's University and the Defence Research Board before becoming Director of Research and Development for Monsanto in 1954. He has done remarkable work in the field of steroids, the stereochemistry of fatty acids, amino acids, explosives, and physiologically active substances. The more than one hundred papers he has published, and the ten patents he has acquired, are eloquent testimonials to his successful work.

An innovator and leader in the study of seaplants. Dr. McLachlan has applied the tecniques of taxonomy, ecology, biogeography, physiology, cytology, and laboratory cultivation to develop our understanding of marine algal biology. He pioneered in the cultivation of marine algae through their life cycle in the laboratory and his work has been of prime importance in establishing industrial cultivation, utilization, and conservation of seaweeds as a major natural resource. Dr. McLachlan is recognized internationally as a leader in the field of marine phycology, and has been involved for many years in international phycological discussions and in the organization of the International Seaweed Symposia.

Digby J. McLaren, M.A. (Cantab), Ph.D. (Michigan) internationally recognized Stratigrapher and Palaeontologist, and currently the proposed Vice-President of the Palaeontological Society, has done research throughout the Arctic and Western Canada, applying lithological and Palaeontological techniques towards establishing the accepted classification and interpretation of Devonian and other Palaeozoic rocks. His research on Stratigraphy, interpretation of carbonate rocks, rhynchonelloid brachiopeds, rugose corals, fossil fungi and possible Precambrian metazoans is described in numerous publications including a contribution to an internationally authored "Treatise". He has proved a capable research manager, first as head Palaeontologist of the Geological Survey and now as Director of the New Institute of Sedimentary and Petroleum Geology.

M.A., Mus.B. (Cantab., 1956), FRCO, LRSM. Distinguished recitalist, and soloist (organ, piano and harpsichord), conductor and broadcaster. In addition to his performances and recordings, he is also well known for major articles in "Grove's Dictionary of Music and Musicians", and a number of important sources of early music in Britain, Japan and Poland. Has taught at University of Victoria, The University of British Columbia and Dean of Music, The University of Western Ontario (appointed 1973).

(46: Professor of Music and Dean, Faculty of Music, University of Western Ontario).

Dr. Hugh McLennan received his academic training at McGill University obtaining a B.Sc. (Honours chemistry) in 1947 and a Ph.D. in 1951. He has recently been recommended for promotion to full professor of physiology at the University of British Columbia. He is an imaginative and productive scientist, and has an international reputation for his work on synaptic transmission in the central nervous system of vertebrates with particular emphasis on inhibition. His monograph on Synaptic Transmission is an inportant contribution to the field and has been well received. Recently, he has developed an ingenious technique for brain stimulation and recording in unrestrained animals, and is applying this to the study of behaviour in cats. Dr. McLennan is an excellent teacher and a mature, competent investigator who has contributed much to Canadian Science.
