Defervesce

[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.

[W]e find that the duration and succession of the febrile phenomena constitute five principal groups. […] 2. Fevers which are essentially continuous in their course (continued fevers), which exhibit but slight daily differences of temperature during their fastigium or acme, and defervesce rapidly (by crisis).

The symptoms gradually improved until, on the fifth day from her delivery, I was pleased to find the erysipelas rapidly defervescing, the lochia natural, no subinvolution of the uterus, nor abdominal tenderness.

Meningococcal meningitis defervesces quickly over one to three days whereas Haemophilus influenzae meningitis resolves over three to five days, and severe pneumococcal meningitis may take a week or longer for the fever to decrease/become afebrile. Viral causes of meningitis or encephalitis defervesce very slowly over a seven-day period, and by monitoring the fever defevescence pattern a clinician can easily differentiate viral meningitis/encephalitis from bacterial meningitis.

[I]n common ſcortation, or ſimple adultery, there is not a love analogous to conjugial love, for it is only a heat of the fleſh, which inſtantly deferveſces, and ſometimes does not leave any trace of love behind it towards it's object; […] It is otherwiſe in the caſe of polygamical ſcortation; herein there is a love analogous to conjugial love, for it doth not deferveſce, is not diſſipated, nor doth it paſs off into nothing after efferveſcence, as the foregoing, but it remains, renews, and ſtrengthens itself, and so far takes away from love to the wife, and in the place thereof induces cold towards the wife; […]

[T]he angry are gone out of power; that is, out of counsel, out of reason, out of mind; for the power of these ought to control the whole soul. […] [L]et them be implored and entreated, if they have some means of revenge, that they will defer it to another time, until anger shall have defervesced. But to defervesce, certainly implies that heated ebullition of mind which has risen in revolt against reason.

Instead, I was still feeling ok after the previous day spent mainly in the Maldivian waters diving and snorkeling, and I had booked for myself two other morning scuba dives on Tuesday. […] Andrea passed the opportunity for these dives today, resting and defervescing from the tour-de-force of the day before.
