Tromboni

"The most convenient and natural order is, perhaps, the following: the upper staff may have the flute-part, because it has the highest notes, and, therefore, requires most room above the staff; then follow the parts for the hautboys, clarinets, horns, bassoons, tromboni, trumpets, and drums; the upper half of the page thus containing the wind-instruments: the lower half belongs to the violins, viola, voices, violoncello, and double base."
