Abstract
REFERRING to Prof. Valentiner's article on “New Facts in Physics,” in NATURE of January 9, you note that Messrs. Reboul and Dr. Bollement have found that copper and silver eject particles at 500° C. in a vacuum, in air, oxygen, and carbonic acid. which forms deposits on the walls of the containing vessel. Pure silver, and several alloys having a chief content of silver, were found by me to emit particles or an emanation of some sort when heated in air to a bright red, but well below their melting points. The facts were observed during an inquiry to ascertain the cause of the sudden failure of the platinum pins of porcelain teeth, and were briefly noted in The Dental Record, September, 1911.
