“ This fluid becomes less and less transparent, until it acquires the colour and consistence of pus. The pustule, during its serous state, is of a rounded form. It is flattened when the fluid acquires a purulent character, and even slightly depressed towards the close of the period of suppuration, and when that of desiccation is about to commence, which ordinarily happens towards the ninth or tenth day of the eruption. The desiccation and the desquamation occupy an exceedingly variable length of time; and so, indeed, do all the different periods of the disease. ”
Desiccation
Definition and stakes
Desiccation, the condition of extreme dryness or the process of extracting moisture, has been examined in scientific, literary, and cultural contexts. Authors such as William Youatt investigated its biological effects, observing how it alters bodily fluids during illness, while H. Charlton Bastian emphasized its fatal influence on microorganisms. In the field of preservation, J.-N.
Gannal outlined desiccation's function in anatomical studies, contrasting its usefulness with its constraints in pathological samples. Religious texts, such as Leviticus, indirectly allude to desiccation's symbolic significance in ritual purity. These diverse viewpoints highlight desiccation's dual nature—as both a natural challenge and a human-developed method—linking biology, technology, and cultural practice.
Quotes about “desiccation”
H. Charlton Bastian,
The modes of origin of lowest organisms
“ Taking into consideration the fate of other simple organisms, however, it is by no means improbable that they should be killed even by a short desiccation. I have found, for instance, that desiccation for half-an-hour in a room at a temperature of 65° F. suffices to kill all the larger, naked, lower organisms with which I have experimented—including long Vibrios, Amœbæ, Monads, Chlamydomonads, Euglenæ, Desmids, Vorticellæ and all other Ciliated Infusoria. ”
Various, The Cornhill Magazine (Vol. I, No… (1860)
“ If not, I am at a loss to explain the contradiction; for certainly in my experience a much more moderate desiccation—namely, that obtained by simple evaporation over a mantelpiece, or under a large bell-glass—always destroyed the animals, if little or no dirt were present.The subject has recently been brought before the French Academy of Sciences by M. Davaine, whose experiments [13] lead him to the conclusion that those Rotifers which habitually live in ponds will not revive after desiccation: whereas those which live in moss always do so. ”
