Definition of "Lushington"

If they have any on hand, and a little stale, at the end of the week, they sell it at the public-houses to the “Lushingtons,” and to them, with plenty of vinegar, it goes down sweet.

1851, Henry Mayhew, “Of the Street-Sellers of Fish”, in London Labour and the London Poor
