Victor Hugo,
Les Misérables — Volume 3, Book Seventh…
“ Beneath the obscure roof of their cavern, they are continually born again from the social ooze. They return, spectres, but always identical; only, they no longer bear the same names and they are no longer in the same skins. The individuals extirpated, the tribe subsists.They always have the same faculties. From the vagrant to the tramp, the race is maintained in its purity. They divine purses in pockets, they scent out watches in fobs. Gold and silver possess an odor for them. There exist ingenuous bourgeois, of whom it might be said, that they have a "stealable" air. ”
