Same etymon. A substance of a soft consistence, tremulous, and transparent, which is obtained, by an appropriate treatment, from animal and vegetable matters: hence the distinction into animal and vegetable jelly. The former is merely a concentrated solution of gelatin, left to cool. Vegetable Jelly is found in the juice of the currant, mulberry, and of almost all acid fruits, when ripe. It is of itself colourless, but almost always retains a little colouring matter of the fruit which has furnished it. It has an agreeable taste; is scarcely soluble in cold water, but boiling water dissolves it readily: the jelly is, however, almost all deposited on cooling. If this aqueous solution be boiled for a long time, it becomes analogous to mucilage, and loses the property of being jellied on cooling.
