Almost exactly a quarter of a century ago—in the year 1906— the George Combe Department of Psychology was established in this University, thanks to the farsightedness of Professor Pringle-Pattinson, who has, to our regret, now gone from among us, and Professor Sir Edward Sharpey Schafer, who is happily with us still, and to the generosity of the George Combe Trustees. In his inaugural lecture, delivered in the old Natural History classroom, my predecessor, Dr. W. G. Smith, discussed the scope and relations of modern psychology. He emphasized the fact that modern psychology had extended its boundaries far beyond the psychology taught in the past in this and other universities, that it now included child psychology, animal psychology, abnormal psychology, physiological psychology, and experimental psychology, all developed studies, and that its growth in importance had been commensurate with its expansion.
