1of 1855, enables this to be more easily understood. Fig. 3 represents the exterior of one of the cylinders. Fig. 4 is a section; the extra tubing may be, of course, of any length required. A, B, and C (Fig. 4) show the different positions of the cylinder when at rest, and when depressed either way. This arrangement, as practically employed, allowed of twenty-six different positions, and the diameter of the wind passages through the cylinders not being constricted, the intonation of the instrument did not suffer.

7B♭ CONTRA-Bass. A monster model, made by Henry Distin for use in the "Flügel Horn Union" in 1862. With three valves; there are two passages only in each valve. The four holes in each piston, being placed vertically above each other, are connected in pairs by semi-circular passages built up within the valves, so that there is no abrupt turn in any of the wind passages. The height of this instrument from the ground is nearly eight feet.

13EUPHONION. With extra set of slides to tune "fourth valve notes." This instrument shows an early device to bring the notes produced by the fourth valve into tune. There are two distinct sets of passages through the valves, and corresponding lengths of tubings; the lower set of three passages in each valve is ordinarily in use; the upper set of three passages in each valve, and duplicate set of tubings, comes into use only when the fourth valve is down. The instrument as it stands is in B♭. With the fourth valve depressed the pitch is lowered to F, the duplicate valve tubings being tuned to agree with this note. This system was probably designed originally by Antoine Courtois, but discarded by him subsequently, and it somewhat resembles that employed by Gustav Besson in his "registre" of 1857, described previously.
