The scientific basis of education demonstrated. By an analysis of the temperaments and of phrenological facts, in connection with mental phenomena and the office of the Holy Spirit in the processes of the mind: in a series of letters, to the Department of public instruction in the city of New York, by John Hecker
A phrenology-based treatise on education, written by John Hecker and published by the author in New York in 1867, addressed in a series of letters to the city's Department of Public Instruction. The pictures are engraved diagrams of a phrenological bust and head overlaid with a gridded globe, its faculty labels such as acquisitiveness and destructiveness scattered across the skull, and a designer could take the nested grid-and-label structure as a model for dense radial diagrams.
