Types
For many centuries, in Europe, North America and elsewhere, commercial proponents of mineral springs classified them according to the chemical composition of the water produced and according to the medicinal benefits supposedly accruing from each:
- Lithia springs contained lithium salts.
- Chalybeate springs contained salts of iron.
- Alum springs contained alum.
- Sulfur springs contained hydrogen sulfide gas.
- Salt (saline) springs contained salts of calcium, magnesium or sodium.
- Alkaline springs contained an alkali.
- Calcic springs contained lime (calcium hydroxide).
- Thermal (hot) springs could contain a high concentration of various minerals.
- Soda springs contained carbon dioxide gas (soda water).
- Sweet springs were springs with no detectable sulfur or salt content (arguably not 'mineral' springs at all).
- Radioactive springs contain traces of radioactive substances such as radium or uranium.

Famous quotes containing the word types:
“The bourgeoisie loves so-called “positive” types and novels with happy endings since they lull one into thinking that it is fine to simultaneously acquire capital and maintain one’s innocence, to be a beast and still be happy.”
—Anton Pavlovich Chekhov (1860–1904)
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
