I find it interesting that there are several bits of cant there which are identical to C19 London thieves cant.

e.g., "Lay" - meaning a scheme to obtain money or goods - the example given was "the Gooseberry Lay"

"Goniff" was also in current use at that time, with the same meaning, and not just among the Jewish Community of London's East End.

The only one that I noticed in there which was in use over here in the C19 and is still current among the criminal classes is "Dip" for picking pockets, usually in the form of "dipper", for the exponent of that art.
