Physiology, animal and mental: applied to the preservation and restoration of health of body and power of mind / by O.S. Fowler.
Physiology, Animal and Mental is an 1847 health and phrenology manual by American phrenologist Orson S. Fowler, published in New York by Fowlers and Wells for general readers interested in preserving body and mind. The pictures are monochrome engravings of the brain in section and profile, a set of teeth, and a skull, with numbered regions and lettered labels. A designer might take their precise, diagrammatic line work and numbered callouts as a model for anatomical labelling in a clean scientific style.
