Illustrations of phrenology : with engravings / by Sir G. S. Mackenzie.
Illustrated treatise on phrenology by George Steuart Mackenzie, published in Edinburgh by Archibald Constable & Co in 1820, aimed at readers interested in the skull as a guide to mental faculties. The engravings show human skulls from several angles, drawn with fine stippled and hatched shading on pale paper. A designer might take the precise line work and sepia tonal shading for anatomical or scientific diagrams.
