The natural history of the human temperaments : their laws in relation to marriage, and the fatal consequences of their violation to progeny, with the indications of vigorous life and longevity : followed by a fugitive essay on the protection of society against crime / by W. Byrd Powell.
A phrenology and temperament treatise by W. Byrd Powell, published in Cincinnati in 1869 by Keckeler, aimed at readers interested in marriage, health and crime prevention. Its engravings are small head-and-shoulders portraits of men in 19th-century dress, with dense hatching and plain tan backgrounds, giving a designer a model for period portrait engraving and for tonal shading built from parallel lines.
