VEG'ETO-ANIMAL, adjective vegeto-animal matter, is a term formerly applied to vegetable gluten, which is found in the seeds of certain plants, in a state of union with farina or starch. It is remarkably elastic, and when dry, semi-transparent. By distillation it affords, like animal substances, alkaline water, concrete volatile alkali, and an empyreumatic oil.
