1position of the fourth valve the shorter set of tubings upon the first, second, and third valves are in use; upon the depression of the fourth valve the longer set of tubings are employed. The pistons are dependent, the fourth valve, when used alone, lowering the pitch of the instrument a semitone. The use of this arrangement rendered the following scales, usually difficult or impossible, easy of execution, viz.: those of \( D_b, G_b, A, \) and \( B, \) whilst the intonation of the harmonic series of \( E \) and of the lower register became perfectly true.
3The system, compared with the same maker's patent of 1857, described upon page 189, and which was made with independent positions, is simpler; and the reduction of the number of air passages through the registre, or fourth valve, renders the instrument less liable to get out of order.
5The same system was applied to all brass instruments, and in the case of the basses, the registre, or "transposing stop," instead of lowering the pitch a semitone, lowered it a perfect fourth, the duplicate valve tubings being constructed of the necessary additional length.

11BARYTONE, in \( B_b, \) with five valves. Made by Gustav Besson about 1857. The first, second, and third valves lower the pitch of the instrument a tone, semitone, and tone and a half respectively. The fourth valve cuts off tubing, and so raises the pitch one tone. The fifth valve lowers the pitch of the instrument a semitone.
13Instruments constructed upon this system were invented in 1857 by Gustav Besson and patented in France. They were known by the name "enharmonique," there being 32 different positions; their use presented many advantages, as regards both intonation and facilities for
