A catechism of phrenology : illustrative of the principles of that science / by a Member of the Phrenological Society of Edinburgh.
A phrenology catechism published in Philadelphia by Carey, Lea, & Blanchard in 1835, written by a member of the Phrenological Society of Edinburgh as a question-and-answer primer for general readers. The plate shows an egg-shaped skull diagram above three heads, two in profile and one frontal, each divided into numbered regions representing faculties. A designer might draw on its tidy numbered grid and engraved shading for diagrams explaining a system of categories or mapping a head or face.
