Dr Leonard Hill’s experiments into decompression procedures were described In The Graphic in August 1907. Dr Hill, Mr M. Greenwood and Mr J. J. R. Macleod exposed themselves to pressures up to seven atmospheres (equivalent to 230 feet depth in the sea) in their tiny compression chamber. They claimed to have decompressed successfully by allowing 20 minutes to decompress for each atmosphere.

In 1867 a ship called the Bubulina, an American blockade runner, sank in the middle of the channel in the River Mersey following a massive boiler explosion. Divers were engaged to recover the guns and portions of the wreck as it interfered with the navigation of the river. A Times report commented that it was strange that none of the bodies of the crew that were killed had yet been recovered.
