Two drachms of putrid bile, which had been kept closely corked in a

phial since the year 1770, and smelled very offensively, were mixed in

a cup with twenty grains of Magnesia, and half an ounce of water, and

thereby restored to sweetness. Twenty grains of calcined Magnesia were

also added to two drachms of the same bile: on stirring them a pungent

smell was observed, like that of volatile salts, and half an ounce of

water being put to the mixture, the bile was totally deprived of any

putrid smell. Even five grains of the same powder sweetened two drachms

of putrid gall.
