The turpentine, which is lighter than water, is drawn off and sold as oil or spirits of turpentine. Figs. 21 and 22 illustrate the process of collection and distillation of tur- pentine. The best grades come from this country and France. Russia produces some oil of poorer quality. It is a colorless, mobile liquid with a faint, pleasant, ethereal odor when pure. On standing there is formed an oxidized compound, probably an aldehyde, which is said to give.
