The mysteries of human nature explained by a new system of nervous physiology : to which is added, a review of the errors of spiritualism, and instructions for developing or resisting the influence by which subjects and mediums are made
An 1857 Buffalo treatise by the American writer J. Stanley Grimes, aimed at general readers, that explains mental phenomena through a theory of nervous physiology and criticises spiritualism. The pictures are anatomical plates of the brain and its base, with numbered lettered diagrams, drawn in fine engraved line on plain paper; a designer might take from them the precise labelled-diagram look of mid-nineteenth-century medical print.
