3Invention Horn, in Eb, with D crook. The interior of the bell of this instrument is prettily painted. The tubing is wound in an ornamental manner, and the crooks fit into the middle of the instrument, as in the French horn previously described (No. 310). This instrument, however, is in reality a hand trumpet. The idea of applying the crooks for changes of key to the middle of the bore, instead of, as previously, to the upper end, is attributed to Michael Wögel, born at Rastadt in 1748. The name of "Invention horn" was given to this instrument in Germany; and it is interesting as showing (excepting the tortil described later, see p. 175) the earliest application of the kind suited for crooks of any length. Length 18 inches.

9Cor Omnitonique. This instrument was invented and constructed by C. Sax, père, of Brussels, in 1824. The bell is engraved with the royal arms of the Netherlands. In this instrument there is no need for the use of crooks. The instrument can be put in any of the keys ordinarily used (i.e. Bb (high), A, G, F, E, Eb, D, C, and the low Bb), by means of a piston which moves in a graduated tube, and which puts the additional lengths of tubing successively into communication with the main windway of the instrument. The interior of the bell of this instrument is beautifully painted. Its greatest width is 23 1/2 inches.
