Excerpt from Gems: Notes and Extracts
Minerals consist of all those substances which have neither animal nor vegetable life, and are therefore devoid of sensation, existing merely by the power of aggregation or chemical affinity.
The science which treats of minerals is called Mineralogy, and is divided into two distinct branches, viz., that which preserves the name, and treats simply of minerals with regard to their component elements, and Geology, which regards minerals pure or mixed, as they exist in nature and in relation to the soil.
Mineralogy describes the individual quality of the various mineralogical species; geology treats only of minerals as constituent parts of the earth.
Those minerals which are used ornamentally and are prized for their rarity are called Gems.
In mineralogy, as in other departments of natural history, minerals are united in groups, forming great classes, which are divided into genera, species, and varieties.
