There is as much difference to my eyes between the leaded bourgeois type of a Times article and the slovenly print of an evening half-penny paper as there could be between your negro and your Esquimau. The detection of types is one of the most elementary branches of knowledge to the special expert in crime, though I confess that once when I was very young I confused the Leeds Mercury with the Western Morning News. But a Times leader is entirely distinctive, and these words could have been taken from nothing else.
