PHRENOLOGY AND PHYSIOGNOMY [Top, from left] the heads of two physiognomists - the Swiss, Jean-Baptiste de la Porta, and the Neapolitan, Jean Lavater. Both portraits have been selected because they exhibit 'large characterioscopicity'. [Bottom, from left], the Scottish mechanic and inventor, James Watt, and the showman, P.T. Barnum: the first is given as an example of 'large structurodexterity', the latter as an example of small, or 'negligible structurodexterity'. Barnum recorded that he did not have the ability even to whittle a barrel tap round. From J. Simms, An Original and Illustrated Physiological and Physiognomical Chart, 1888 edn (first printed 1873).
