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 Gipsy term, although nowadays it refers to low or vulgar language of any kind, other than cant. Slang and Gibberish in the Gipsy language are synonymous; but, as English adoptions, have meanings very different from that given to them in their original. [6]
