Morley acquired a method of treating scrofula and other similar diseases, and first published it as An essay on the nature and cure of the king's evil (1760). The principal cure, it appears, was a preparation of vervain root. The work was still in print in 1800, when a thirty-second edition was published. (Oxford DNB).
