chemist gnome - finally!!!

There was something ghost-like and insubstantial about gases to these early chemists. They called liquids that turned into gases easily, "spirits." Methyl alcohol, they called "wood spirit"; ethyl alcohol, "wine spirit." Even today, alcoholic beverages are frequently referred to as "spirits." (Modern Arabs, from whose language the word "alcohol" was taken, call ethyl alcohol "spirit" from the English. This is a queer exchange.) - I. Asimov
