    THE PUYSICS OF THE HYDRO-ELECTRIC BATH. More than once during recent years the present writer has tried by direct experiment to throw light upon some of the physical and physiological problems that present themselves in connection with the thera- peutic use of the hydro-electric bath. With a growing experience and improved methods of investigation, his opinions have from time to time undergone modification. But his latest experiments point to conclusions in startling contrast with many pre- conceived ideas. It is not that previous experimental data have proved inaccurate, but rather (1) that the deductions drawn therefrom do not always seem to be warranted by a fuller knowledge of facts ; (2) that these data have in some instances been arrived at by methods which it would now appear are in themselves inherently faulty. The problem is this : With a given current running through a given bath what proportion of such current will find its way through the body of the immersed patient ? In answer to this question various estimates have been hazarded ranging between 5 per cent, and 20 per cent, of the total current. It is obviously a question of the relative resistance or the bath water and of the immersed body. Many different
