Locke, Blackett & Co., and was patented in the form adopted by them about fourteen years since. The action of this process is dependent on the affinity of zinc for silver. The following is a brief description of it: A charge of silver lead, usually about fifteen tons, is heated to a point considerably above that which is used in either the Pattinson or the steam process.
It is one which should commend itself especially to engineers, as in it mechanical means are employed, instead of the large amount of hand-labor used in the Pattinson process.
Pattinson, was read before the British Association in September 1838. In some alloys, according to Turner "Chemistry" page 210, the heaviest metal sinks, and it appears that this takes place whilst both metals are fluid.
That, of course, isn't an unusual thing, but there was a rather curious white mark on his left temple. If he was ever a friend of yours, that scar ought to fix it."

"The Askews seem fated to give me trouble," he went on. "Now the fellow has begun to drain, his neighbors will expect me to do so. In fact, Black and Pattinson bothered Hayes about some plans for buying pipes when they paid their rent.
The advantages of the steam process, as compared to the old six-ton Pattinson pots formerly used by the writer's firm, are: a saving of two-thirds amount of fuel used; the saving of cost of calcination of the lead to the extent of at least four-fifths of all that is used; above all, a saving in labor to the extent of two-thirds.
He paused again with a little expressive gesture. "It seems due to him, and you, that I should tell you this. When no word reached us I had inquiries made, through a banker, who, discovering that he had registered at a hotel as Pattinson, at length traced him to a British Columbian silver mine.
