Metallurgy, is said of silver, when, in the operation of refining, the lead being burnt away, the remaining copper rises upon its surface in red fiery bubbles.

the sea language, is said of a ship when an anchor being let fall does not hold her fast, nor prevent her sailing away with the wind or tide.
