Somnolism & psycheism, or, The science of the soul and the phenomena of nervation, as revealed by vital magnetism or mesmerism : considered physiologically and philosophically, with notes of mesmeric and psychical experience
Somnolism & psycheism is an 1851 London mesmerism treatise by Joseph W. Haddock, published by James S. Hodson, written for a general reader interested in vital magnetism and the nervous system. The four pictures are numbered anatomical engravings of the brain, its base, the sinuses and the nerve roots, drawn in fine black line on a cream ground. A designer could draw on their dense hatching and clean labelled diagrams for scientific or occult-themed layouts.
