New York, Columbia University, 1938. Manuscript. Hardback. A very good copy. I've noted this as a manuscript, but rather it's a privately printed book given it was produced as part of a PhD by Everts. There are copies in UK universities, so I presume it was published to some extent. The book bears the stamps of the University of London and a bookplate. Simple binding. [9846, Hyraxia Books].
