The criminal tattooers of Naples have the habit of making long inscriptions on their bodies; but initials are used instead of words. Many Camorrists of Naples carry a tattooing which represents iron bars, behind which there is a prisoner and underneath the initials Q. F. Q. P. M.; which means: "Quando finiranno queste pene? Mai!" (When will these pains end? Never!) Others bear the epigraph C. G. P. V., etc., which means: "Courage, galeriens, pour voler et piler; nous devons tout mettre à sang et à feu!" (Courage, convicts, to steal and to rob; we must put all to the sword and fire!) We see here at once that certain forms of tattooing are employed by criminal federations, and serve as a sort of rallying-call. In Bavaria and in the South of Germany, the pickpockets, who are united together in real alliances, recognise each other by the epigraphic tattooing "T and L," which means _Thal und Land_ (valley and country); words which they must exchange in a low voice when they meet each other, in order not to be denounced to the police. A thief R..., who has on his right arm a design representing two hands crossed, and the word _union_ (unity) surrounded by a garland of flowers, told us that this tattooing is extensively adopted by malefactors in the South of France (Draguignan). According to the revelations made to us by emerited Camorrists, a lizard or a serpent denotes the first grade of this dangerous association. I pass over in silence, and for good reasons, the tattooings spread over all the remaining parts of the body.
