This recently came via the web site. Two works that have been put into electronic format by the University of Saskatchewan library are:
Time and Tide: a study of the poetry of George MacDonald
Towards an understanding of George MacDonald : a study of symbolism in the fantasy works
Both were thesis publications of the late Dr. Margaret R. Parsons. She was a great admirer of MacDonald’s works and devoted a great deal of time and energy into her research. Since her theses were never published other than for deposit in the Univ. library they were not readily available until they recently scanned and posted them online.
