Some ascribe all three to Tromlitz, and others (with considerable probability) to Joseph Tacet, who certainly was one of the first to employ them.

He was a grandfather of Cipriani Potter; and Richard Potter (the well-known London flute-maker) adopted these keys on a flute made in or before 1774, on which Vanhall performed at The Hague, and which he subsequently sold to Ashe, the Irish flautist. This doubtless is the instrument referred to in the Encyclopédie Methodique (1785)—"It is pretended that an English musician has constructed a flute with seven keys in order to obtain all the semitones." Potter in 1785 took out the first English patent for improvements in the flute; it included these keys, also a metal tuning-slide, a screw-cork in the head-joint, and conical metal valves on the keys. He, however, makes no claim to
