The phrenological delineator : A compendium of phrenology; including recent discoveries in relation to the brain, temperaments, and other conditions of body which affect mentality. Together with a chart of the phrenological developments ... / By D.P. Butler.
A phrenology compendium published in Boston in 1858 by D. P. Butler, aimed at readers interested in the mind and the temperaments. Its pictures are fine-line wood engravings of profile heads, showing a male and a female head in side view with hair and ear detail, plus numbered skull-zone charts that map faculties across the scalp. A designer could take the clean numbered grid and sharply drawn profiles as a model for diagrammatic labelling and vintage scientific chart styling.
