Ferguson collection, Scottish witches illustrations

Part of my Halloween series.
John Ferguson (1837-1916), Regius Professor of Chemistry in the University of Glasgow from 1874-1915, is best remembered for his Bibliotheca chemica, Glasgow, 1906, which is a standard tool for every investigation in the history and bibliography of chemistry. Ferguson was a keen book collector and in 1921 an important section of his private library was bought by the University of Glasgow. This consisted of over 7000 books and some 300 manuscripts. Most of the books in the Ferguson collection are on chemistry and alchemy, but there are important smaller groups of books, such as those on
magic and witchcraft,gypsies, astrology,
Rosicrucians and Cabbalism.
