Abstract
I WAS much interested in the account given in NATURE of October 23 of the new methods of extraction of aluminium from clays of the kaolin class (formed from the denudation of volcanic rocks) by means of nitric acid and electric furnaces in Norway. When this source of production is generally adopted, as no doubt it will be owing to the diminishing supplies of cryolite and bauxite, it seems probable that the vast quantities of “decomposed porphyry” discovered by the late Prof. Jacob during his geological explorations in the Rocky Mountains (some of which have been mistaken for chalk by prospectors) will then form an inexhaustible source of supply for that valuable metal.
