Note 46 — MINERALS.
Reading edition
Sulphur is a simple combustible substance, of yellow colour, which is found pure, or native, in several parts of the world, and is sufficiently familiar to us under the name of brimstone (211). It strongly attracts oxygen (21), and is thereby converted into sulphuric acid (24). It frequently occurs in combination with mineral substances, such as arsenic, antimony, copper, and other metallic ores.
