Scotch divine, born at Dundee, 1698, and educated at Aberdeen. Upon his publication of a pamphlet on the inconsistency of a civil establishment with Christianity, he was deposed from his church, near Dundee, and then became the founder of a new sect, called the Glassites in Scotland, and Sandemanians in England. As the discipline of his sect was very rigorous, few embraced his tenets, and the name is scarce known now.
