 | | The earth and all things pertaining thereto are composed of simple substances; but what number of simple substances are comprised in the whole is not yet ascertained, as there are some bodies which evidently partake of different ingredients, but which have not yet been decomposed. |
 | | Among those which are considered to be simple are Light, Heat, Oxygen, Hydrogen, Carbon, Platinum, Gold, Silver, Mercury, Copper, Tin, Iron, Lead, Nichel, Zinc, Bismuth, Antimony, Tellurium, Arsenic, Cobalt, Manganese, Tungsten, Uranium, Titanium, Columbium, Tantalium, Cerium, Nikel, Potassium, Sodium, Lime, Alumine, Silex, Magnesia, Barites, and Strontia, or Stronites, with several others, less generally known. |
 | | Of these, several have recently been proved to be metals, which were formerly supposed to be merely earths; and even the alkalies, potash and soda, are frequently reduced to a pure metallic state. |
