Le Triton. La Navigation sous-marine. [With illustrations.]. Paris, 1906. Experimental underwater breathing apparatus, known as the Triton, designed by Frédéric de Drieberg. The diver wears a metal air cylinder on the back and a metal crown on his head, which is connected to a pair of bellows also worn on the diver's back. By nodding his head, the diver causes the bellows to suck air down from through a tube leading from the surface. Image taken from La Navigation sous-marine. [With illustrations.].
