Bottle, probably made by Thomas Beddoes & James Watt

This iron bottle for generating oxygen dates from around 1800. It is thought to have been part of an apparatus produced by Thomas Beddoes (1709-1808) and James Watt (1736-1819).

The iron bottle is fitted at its mouth with a cylindrical iron adaptor, into which is jammed a conical iron tube. When the bottle is placed in a fire, it produces oxygen from manganese dioxide.

Thomas Beddoes was an Englishman who studied medicine under Joseph Black at Edinburgh. He believed in the therapeutic effect of inhaling gases, including oxygen for asthma.
