FWIW, that is as it should be, I would say. Furnivall is one of the great names of nineteenth century English literary scholarship. John Hales was mostly a scholar of Edmund Spenser and didn't do anything else of significance to folk music scholars that I know of. And he was too squeamish to do the "Loose and Humorous Songs" in the Percy Folio; Furnivall did that solo.
