Etherology, or, The philosophy of mesmerism and phrenology : including a new philosophy of sleep and of consciousness : with a review of the pretensions of neurology and phreno-magnetism
Etherology, by the American writer J. Stanley Grimes, was published in New York in 1845 by Saxton and Miles as a treatise on mesmerism, phrenology and sleep for a general readership of inquirers. The two profile head diagrams number the phrenological organs in numbered regions across the skull and face, and the third plate is a library seal, so a designer could take from them the look of a numbered anatomical key set over a cartoon profile.
