Their application is made for short periods periodically, all the usual means for obtaining anti- or asepsis being used. Hot air hyperaemia ; arterial hyperaemia,—-This is, of course, a different type of hyperaemia to that pro¬ duced by obstruction, being the result in the first place of an active determination of blood to the part, as opposed to passive or obstructive engorge¬ ment. It is singularly well adapted for the treatment of chronic thickenings, infiltrations and adhesions when not too old, since absorption is much aided by the flushing of the parts with healthy blood, which occurs in the process. In certain neuralgic and other pains it is of remarkable, although uncertain, benefit. Here, as in the cases of the obstructive bandage and the suction method, no pain or discomfort should be caused by the heat, and in this connection it is most important to bear in mind that with increasing heat the part becomes less and less sensitive; at a heat of 250 or 300 degrees the sensation in a limb is almost nil, hence burns may occur without the patient's knowledge—a fact which does not seem to be too familiar even to those who are in the habit of applying this method of treatment.
