The Internet Archive has a complete scan of James Redding Ware's wonderful 1909 treatise "Passing English of the Victorian era: a dictionary of heterodox English, slang and phrase," ganked from the University of Toronto's Robarts library. The Archive has OCR'ed versions, hi-rez PDFs of color and b/w scans, and every ebook format you're likely to need.

bag'. ' I will not buy a pig in a
poke !' Camden.
He denied that when entering the
music hall he was accused by a larty of
