Phrenology made practical and popularly explained / by Frederick Bridges.
Phrenology Made Practical and Popularly Explained, a popular London handbook by Frederick Bridges published by George Philip & Son in 1861 for general readers interested in the pseudoscience of skull measurement. Its pictures show four profile heads of men with a superimposed grid of lettered squares, circles and diagonal lines marking the proportions used to read character from the skull, with numerals such as 40, 53 and 67 in the corners. A designer could take the clean geometric overlay and the engraved hatching of the bust forms as a model for diagram-style illustration.
