WE regret to announce the death of Arthur Lionel Pedder, on December 15, at the age of sixty-six years. He was mathematical tutor at Magdalen College, Oxford, from 1891 until 1925. He went to the College as a demy in 1886, and was elected fellow in 1894. Pedder was a very good teacher and was remembered with gratitude and affection by his pupils. He was one of the old-fashioned people who valued the educational training given by the curriculum and examinations of the old mathematical school as one of the best preparations for after-life; and was quite out of sympathy with the new system which, in his opinion, was of little or no use, except for those who intended to be professional mathematicians.
