The self-instructor in phrenology and physiology; with over one hundred new illustrations, including a chart for the use of practical phrenologists
A self-instruction manual on phrenology and physiology, written by the Fowler brothers and Nelson Sizer and published in New York in 1890 for lay readers and practical phrenologists learning to read head shapes. The pictures are small wood-engraved profile portraits of bearded men in side view, with hatched shading on hair, beards and collars, showing how a designer might render character through a single outline and dense cross-hatching.
