[Carl Reinhold August] Wunderlich, who has made probably more observations with the thermometer than any other living man, has determined, for example, that in simple croupous pneumonia, where the temperature does not exceed 104°, Fahrenheit, the pulse 120, and the respiration 40 in the minute, the case may be considered a favorable one; will surely reach its crisis in from six to ten days, and defervesce, without any medical treatment, except proper attention to the ordinary hygienic and dietetic rules.
