What is a purloiner? (From Dickens' A Tale of Two Cities)

A purloiner is a thief.

Accordingly, the forger was put to Death; the utterer of a bad note was put to Death; the unlawful opener of a letter was put to Death; the purloiner of forty shillings and sixpence was put to Death; the holder of a horse at Tellson's door, who made off with it, was put to Death . . .
