He was an inspiring teacher. He gave optional weekly lectures to the honours class on modern developments in mathematics which, for insight and judgment, were years ahead of their time and which were very much appreciated. He did the hack work of the department in a conscientious and efficient manner. He took a personal interest in all his students. When I went to Göttingen in 1903 he gave me letters of introduction to two German mathematicians. He was specially helpful to students preparing for the Indian Civil Service examination, of whom there were many at that time, and he was secretary of an incipient staff association. His departure was a great loss to Glasgow, but, of course, it was Australia's gain.
It is not necessary to mention his books here, as they are very well known.
