page 362 note 1 Schlœsing's apparatus consists of a coal-gas and compressed air blow-pipe, similar in principle te Griffin's blast-furnace, and with which in about half-an-hour may be melted several hundred grammes of malleable iron.

page 363 note 1 We employ in preference the name of “Bronzite,” because it is this mineral which in terrestrial rocks most generally accompanies Peridote and Serpentine, and because besides nothing proves that the proportion of the iron in the fused bi-silicate has not diminished by fusion. M. Daubreèe employs the name of Enstatite, which it would be well to restrict to the type of pure bi-silicate of magnesium, which is as rare in nature as the bi-silicates of iron and calcium, of which the mixture in diverse proportions constitutes the extensive group of pyroxene and amphibole.
