 | | In Britain, for very many years after public interest in scuba diving began around 1953, the word "aqualung" was commonly used in speech and in publications as a generic term for divers' open-circuit demand-valve-controlled breathing apparatus; and also in figurative uses such as "the water spider's aqualung of air bubbles". |
