Physiology of the Turkish Bath.—Most accounts of the Turkish bath have been confined to general descriptions of the details of the process, and of the sensations experienced during its use; while comparatively little attention has until lately been paid to the more important consideration of its influence on the bodily functions. To supply this need, Mr. William James Fleming, M.B., Lecturer on Physiology in Glasgow, began some years since a series of careful experiments with the action of the bath on his own person. These were continued down to a recent period, and we now have the results of the investigation in the form of a valuable paper published in vol. xiii. of the "Journal of Anatomy and Physiology."

To those not acquainted with this form of bath it will be sufficient to say that the essential part of the process consists in the immersion of the body in dry air at a temperature varying from 130° to 200° Fahr. for from half an hour to an hour generally, and subsequent douching with cold water.

Mr. Fleming's experiments were all made between lunch and dinner, usually from 4 to 6, in a bath heated by Constantine's system. This is an arrangement of stoves by which a constant current of pure air is drawn from the outside atmosphere, heated by passing through a species of oven, and driven into one of the apartments of the bath with such force that it traverses the whole suite of rooms, parting with some of its heat in each, and ultimately escaping from the last into the outer air again. By this means not only the air for breathing but also that in contact with the skin is constantly renewed, so that a layer of watery vapor does not, as in all baths heated with stationary air, soon cover the body, and thus convert the bath into a vapor one. The experiments usually began with a heat of about 170° Fahr. for a few minutes, in
