horizontal one, and we have the half revolution of Bacchus and Victory,
as well as the complete revolution of the bacchantes.

The successive lighting of the two altars, the flow of milk and wine,
and the noise of drums and cymbals were likewise obtained by the aid of
cords moved by counterpoises, and the lengths of which were graduated
in such a way as to open and close orifices, at the proper moment, by
acting through traction on sliding valves which kept them closed.

Small pieces of combustible material were piled up beforehand on the two
altars, the bodies of which were of metal, and in the interior of which
were hidden small lamps that were separated from the combustible by a
metal plate which was drawn aside at the proper moment by a small
chain. The flame, on traversing the orifice, thus communicated with the
combustible.

The milk and wine which flowed out at two different times through the
thyrsus and cup of Bacchus came from a double reservoir hidden under the
roof of the temple, over the orifices. The latter communicated, each of
them, with one of the halves of the reservoir through two tubes inserted
in the columns of the small edifice. These tubes were prolonged under
the floor of the stage, and extended upward to the hands of Bacchus. A
key, maneuvered by cords, alternately opened and closed the orifices
which gave passage to the two liquids.

As for the noise of the drums and cymbals, that resulted from the
falling of granules of lead, contained in an invisible box provided with
an automatic sliding-valve, upon an inclined tambourine, whence they
rebounded against little cymbals in the interior of the base of the car.
