bathyscaphe

A bathyscaphe is a self-propelled submersible used in deep-sea dives.

The US Navy had acquired a submersible called the bathyscaphe Trieste and Don, a submarine lieutenant, volunteered to join the project.

He too will have to descend in bathyscaphe if he is to keep even the friendliest papers interested in photos of his working life.

Yet there is still not a bathyscaphe or diving bell.

I step out on the foredeck of my ship–bathyscaphe, precious package in my hands.
