A new musical instrument. It is very sonorous, the upper notes approximating closely to those of a horn, though much softer; the lower notes blending very harmoniously with those of the voice, piano-forte, etc. The compass of the instrument is three octaves, commencing with the C in the second space bass clef, or four notes lower than the fourth string of the violin, continuing to the C the second ledger line above the treble stave, with their intermediate semi-zones. It is played with a reed and mouth-piece similar to a clarionet. The annexed representation, although like the small bassoon, differs materially in its tone and compass. There are three keys and key-holes on the opposite side to that delineated.
