The curve represents the hydrolysis of Experiment 3. It may be concluded that animal lactase is a gluco-lactase like the lactase in emulsin. I wish to thank Dr. Plimmer for suggesting these experiments and for assistance in the methods A. 2-5 per cent, lactose B. 2-5 per cent, lactose + 2-5 per cent, glucose.
