A mysterious listing in The English Catalogue of Books for 1906 (published 1907 by Sampson Low, Marston & Co., Ltd.):
Hegel not Haeckel; or, Riddle of the Universe Solved!
"Edited by a Student of Hegel"
(published by Simpkin, 1906)
Apparently a reference to German zoologist, Ernst Haeckel (1834-1919).
