Abstract
IN the Journal of the American Chemical Society, vol. ii., Mr. P. Collier describes a new mineral from the Champlain iron region, which resembles thorite in its physical properties, but differs therefrom in containing a relatively large quantity of uranium. Analysis showed 9.96 per cent. of uranic oxide, and 52.07 per cent. of thoric oxide, with 19.38 per cent. of silica, the remainder consisting of oxides of lead, aluminium, iron, calcium, magnesium, and sodium, with moisture and combined water.
