GEL'A-TIN, n. [It. and Sp. gelatina, from L. gelo, to congeal, to freeze.]

A concrete animal substance, transparent, and soluble slowly in cold water, but rapidly in warm water. With tannin, a yellowish white precipitate is thrown down from a solution of gelatin, which forms an elastic adhesive mass, not unlike vegetable gluten, and is a compound of tannin and gelatin. Parr.
