or has repeatedly verified, shows that heating takesplace at quite a different rate, the maximum temperaturebeing reached at very different periods, according to themode of applying the bandage and the degree of protectionafforded (Exp. 69, 70). When lightly covered, the heating compress slowly coolsby evaporation, producing an active fluxion in the associatedviscera; and by the improved circulation and nutrition, thenormal conditions are restored, and the passive congestion isovercome. With each reapplication there is contraction ofthe arterial walls, which empties the blood-vessels, and dis-lodges the leucocytes which may be adhering to the vesselwalls, thus antagonizing inflammation and chronic congestion.As the compress warms up, the vessels gradually dilate again,and the blood moves with increased velocity. The degree of reaction also depends very much upon thecondition of the patient. Bloodless, very feeble patientssometimes react very slowly, and in a particular case the effect

THE TECHNIQUE OF HYDROTHERAPY. 827 of a well-protected compress may not be greater than thatof a partially protected compress with another person. Thisfact must be constantly considered in giving directions respect-ing the application of the heating compress. In persons in whom reaction takes place very slowly afterthe application of the compress, so that uncomfortable chilli-ness and other disagreeable symptoms are experienced, thesurface with which the bandage is to come in contact shouldbe vigorously rubbed with the dry hand until red, or with thehand or a friction mitt dipped in water at a temperature ten orfifteen degrees below the temperature of the bandage. The colder the water, the drier should be the compress.The smaller the compress, the sooner will reaction occur.During the warming-up period, before superheating begins,the effect of the heating compress is highly tonic, excitingall the functions of the skin and the internal parts connectedwith the area treated.
