Page 75 - Let a mass of matter be supposed to consist of spherical particles all of the same size, but of two different kinds in equal numbers, represented by black and white balls; and let it be required that, in their perfect intermixture, every black ball shall be equally distant from all surrounding white balls, and that all adjacent balls of the same denomination shall also be equidistant from each other.
Page 112 - The specific gravity of a mineral is its weight compared with that of another substance of equal volume, whose gravity is taken at unity.
Page 290 - In the matrass it loses its water, and becomes yellowishgreen and friable. When heated to a certain point upon charcoal, it is reduced in an instant with a kind of deflagration, leaving a globule of malleable copper, with white metallic particles dispersed throughout it, which are entirely volatile at a continued blast.

Page 107 - AE, is farther from the same perpendicular than if it had proceeded in the original direction DE. We have therefore this important principle : Light, in passing from a rarer to a denser medium, is refracted TOWARDS the perpendicular ; if from a denser to a rarer, it is refracted FROM the perpendicular.
