Lectures on mental science according to the philosophy of phrenology : delivered before the Anthropological Society of the Western Liberal Institute of Marietta, Ohio, in the autumn of 1851
A set of lectures on phrenology, the 19th-century theory that mental faculties map onto skull regions, given by George Sumner Weaver to a Marietta, Ohio society and published in New York in 1854 for a general readership of students and reformers. The pictures are plain wood-engraved portrait heads and profiles of men in dark coats, with cross-hatched shading and light, unfussy backgrounds that suit editorial or historical reference work.
