Asreaction sets in, the chilliness disappears, and gives place toa sensation of comfort and well-being. Nervousness, whenpresent before the application, is somewhat aggravated duringthe first few minutes after the patient enters the pack, butsoon disappears, and a sensation of delicious calm pervadesthe system, and in many cases the patient falls asleep. Schiiller, in his experiments upon rabbits, noticed that thevessels of the brain, which were dilated at first, as soon asthe general reaction set in, began to contract, the brain sub-stance steadily shrinking, while the dura bulged more andmore through the accumulation of lymph. This condition isone most favorable for the production of sleep and repairof the brain structure. It is the condition present during

Later, as the heat thrown off by theskin, which is greatly increased in amount by the dilatationof the surface vessels, warms up the wet sheet, the heataccumulates in the covering about the patient, and the tem-perature of the blood is raised sufficiently to induce generalperspiration, the beginning of which is indicated by themoistening of the brow. If the pack is continued for several hours, perspirationwill continue, growing more and more profuse for one or twohours, and possibly longer in some cases, but sooner or laterthe activity of the sweat-glands will cease, their energy seem-ing to be exhausted.

The actual effects produced willdepend, then, upon the leng
