Notes:
Jar of sea water, mixed with alcohol, resulting in precipitate of gypsum. A most interesting specimen. There are two original labels on the jar. One says "Artificial "Bathybius" prepared on board H.M.S. Challenger by Sir John Murray". The other says "1 oz salt H2O 3 oz Spirit 4th March 1876 South Atlantic". Bathybius was the name given to the white slime found in many alcohol-preserved deep marine samples by Thomas Huxley, who thought it to be the primitive link between living and non-living matter from which more organised cellular life forms had evolved on Earth. This idea was disproved on the Challenger cruise when one such sample was analysed by JY Buchanan. The white precipitate found simply to be calcium sulphate, rather than anything organic.
