Chlorophyl

( Chem.) The green coloring-matter of plants. It is a resinous substance containing carbon, hydrogen, nitrogen, and oxygen, which cannot be crys tallized or distilled, and has therefore never been obtained in so pure a condition that its composition could be accurately determined. When green leaves are boiled with alcohol, the latter acquires a fine green color, and, when evaporated, deposits its chlorophyl. Chlorophyl lite, n. [Gr. chloros, green, phyllon, a leaf, and lithos, a stone.] ( Min.) An altered variety of Iolite. It occurs at Haddam, in Connecticut, in large prisms, or in foliated ma es, of a grayish or brownish green color - usually a ociated with Iolite in granite. The name has reference to the color and structure of the mineral.
