" Clognini, an Italian physician, ordered two or three drachms of crude mercury to be worn as a defensive against the jaundice; and also as a preservative against the noxious vapours of inclement seasons: "It breaks," he observes, "and conquers the different figured seeds of pestilential distempers floating in the air; or else, mixing with the air, kills them where hatched."

To be brief, he falls three degrees short of his promises, yet is he the key to unlock terms and law days, a dumb mercury to point out highways, and a bailiff of all marts and fairs in England.

Their theory regarded gold as the most perfect metal, all others being removed from it by various stages of imperfection, and they sought an amalgam of pure sulphur and pure mercury, which, being more perfect still than gold, would transmute the baser metals into the nobler.

The sublimed mercury is condensed and collected in the water; and on the completion of the process the tank is lowered, and the spongy or porous cone of silver is withdrawn from the retort.

The water does not freeze until the thermometric mercury tumbles down to eighteen degrees above zero, or fourteen below the ordinary freezing point.
