Note 6 — THE HISTORY OF CANT, OR, THE SECRET LANGUAGE OF VAGABONDS.
Reading edition
The word Slang, as will be seen in the chapter upon that subject, is purely a Gipsey term, although now-a-days it refers to low or vulgar language of any kind,—other than cant. Slang and Gibberish in the Gipsey language are synonymous; but, as English adoptions, have meanings very different from that given to them in their original.
