Abstract
1. The electrical potential of frog skin measured through Ringer's solution and Ag-AgCl electrodes is not altered by 1 per cent sulfanilamide.
2. The oxygen consumption of frog skin is depressed about 40 per cent by 1 per cent sulfanilamide.
3. Neoprontosil and sulfamido-chrysoidin have no effect on the electrical potential or oxygen consumption of frog skin.
4. The excised auricles of the turtle are chronotropically and inotropically stimulated by 1 per cent sulfanilamide.
5. The oxygen consumption of slices of ventricle of the turtle heart is not affected by 1 per cent sulfanilamide.
