Abstract
The equilibrium size and stability of a bubble in a closed constant volume of a liquid-gas solution maintained at a constant temperature are examined. It is found that there are two equilibrium sizes. The smaller size corresponds to an unstable equilibrium state; the larger to a stable equilibrium state. If a bubble is nucleated in the volume, it would grow to the larger equilibrium size. The stress that could be generated by a bubble growing within an osteoclast cavity during a dive is examined. That stress is compared with the stress found necessary to fracture the semicircular canal bone in the inner ear of squirrel monkeys.
