Presentation copy, with a slip inscribed by John Robert Gregg tipped in on the front flyleaf. This curious edition of the classic detective story featuring Sherlock Holmes is written entirely in Gregg shorthand and was intended to promote use of the system. Gregg shorthand is a form of stenography that was invented by John Robert Gregg in 1888. Like cursive longhand, it is completely based on elliptical figures and lines that bisect them. It remains the most popular form of pen stenography in the United States. Small octavo: [2], 188 pp. with shorthand plates written by Alice Rinné Hagar. Original brown cloth binding, with dark brown-stamped titling, borders, and emblem on the front panel. Tiny bit of rubbing to the corners and tips; else near fine.
