This final period of Principal Dawson's work saw a sure and steady advancement and many changes in the University. Among the evidences of growth were the establishment of courses for women in 1884, with their extension in 1886; the addition of the Medical Building in 1886, and its still further enlargement in 1893; the endowment of several chairs; the increase in the teaching staff; the establishment of scholarships and exhibitions; the creation of new courses, and the plans for new and much-needed buildings. In 1886 the Vice-Principal, the Rev. Dr. Leach, retired after over forty years of service. He was succeeded as Vice-Principal by Dr. Alexander Johnson, Professor of Mathematics. Towards the close of this period the Faculty of Applied Science, which had been established as a separate school in 1878, was placed, at last, on an independent foundation--after its many trials and struggles--by the munificent gifts of Thomas Workman and William C. Macdonald, afterwards Sir William Macdonald, a native of Prince Edward Island. Preparations were made for the erection of Science buildings with adequate equipment and endowment. In February, 1893, a few months before Sir William Dawson's resignation of the Principalship, two buildings for the Faculty of Applied Science were opened--the Macdonald Engineering Building, including the Workman wing, and the Macdonald Physics Building, the equipment and facilities of which soon afterwards enabled Professor Ernest Rutherford to carry on his experiments in radioactivity. Meanwhile the Library in Molson Hall had become totally inadequate for the volumes and documents that had been gathered by the University. Peter Redpath, who had already given the Museum, was now the Senior Governor of the University. On November 12, he wrote to the Chancellor enclosing plans of a projected library and proposing to commence building operations early in the following spring. The building was practically completed before Sir William Dawson's retirement, but it was not formally opened until October, 1893. In the last four years of the Principalship of Dr. Dawson the University was given more than a million and a half of dollars for endowment and equipment. What gratified him most in receiving this amount was the fact that it included many minor gifts which testified, at the close of his long career, to the good will and confidence and co-operation of the general public.
