Abstract
Two addresses delivered by the president, Dr. F. W. Frerichs, at Chicago and Washington are chiefly devoted to descriptions of six problems in chemical -engineering practice. One of these, the extraction of bismuth from carbonaceous ores, consists of a complete account of the recovery of this metal from ores containing 1 oz. of lead, 15 oz. of silver 5 per cent, lead, and 5 percent, of.bismuth. The metal can.be produced greatly in excess of the consumption, which in 1910 was about. 200,000 lb for the United States. It is used. almost exclusively for, medicinal purposes.
