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:
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
“The American man is a very simple and cheap mechanism. The American woman I find a complicated and expensive one. Contrasts of feminine types are possible. I am not absolutely sure that there is more than one American man.”

“He’s one of those know-it-all types that, if you flatter the wig off him, he chatter like a goony bird at mating time.”
