Notes on the United States of North America, during a phrenological visit in 1838-9-40
George Combe's 1841 Philadelphia travel account of phrenological lectures and observations in the United States during 1838 to 1840, written for a general reader interested in the science of the skull. The pictures are plain line drawings of head profiles and skull outlines marked with letters, dashed lines and numbered zones, showing how phrenologists divided the head into regions of faculty. A designer might take the clean diagrammatic labelling and the schematic profile heads as a model for scientific chart-style layouts.
