(After Kingsbury.) mammalian intestine afford a greater absorptive surface. The cross-folds delay the passage of food, and Jacobshagen (1915) believes their arrangement may have some systematic value. Urodeles but no frogs have glands between the folds of the small intestine. They resemble the pyloric glands of the stomach, although ducts may be absent (Goldsmith and Beams, 1929). The small intestine is sharply marked off from the stomach by.
