The constitution of man considered in relation to external objects / by George Combe.
George Combe's 1860 Edinburgh and London treatise on phrenology, The Constitution of Man, is a mid-nineteenth-century popular science book for general readers that presents skull and head diagrams. The pictures show profile and rear views of heads with numbered cranial zones, plus a bald man in a high collar, so a designer might draw on their clean line work and the formal Victorian diagram style of numbered measurement lines.
