In like manner, an increaseof the temperature, if it passes a certain limit, which is different for dif-ferent individuals, involves first disturbances to the general health, andlater loss of consciousness, while the centers of the medulla remain func-tional. In general it may be said that the body stands a fall better thana rise in its temperature. A rise of only 2° or 3° C. causes very severedisorders, and experience has showm that a temperature of 41°-42° C. con-stitutes a very dangerous symptom. And 3et a man can endure still higher.

The highest authenticatedtemperatures of patients who afterwards recovered are: ° C, sunstroke;44° C, scarlatina, malaria; 46° C, malaria ( ?). After death the body of course cools down, but not always it has been shown that the temperature of a body which has died frominfectious fevers or injuries to the brain or medulla rises for a time. This isan indication that the metabolism and consequent heat production do notcease everywhere in the body the moment the patient draws his last breath. Alsoafter death from chronic, long-continued diseases, where no such post-mortalrise of temperature is observed, the man
