Desudatio

(From desudo, to sweat). See Ephi-drosis. It is also profuse sweat, succeeded by an eruption of pustules, called sudamina, hydroa, and boa: these are of the miliary kind.

Desurrectio

(From desurgo, to arise from). The same as desessio; but, though the derivation of the two terms appears to be widely different, they have been used in the same sense, to go to stool. Castelli.

Detentio

(From detineo, to detain). See Ca-talepsis.

Detergens

(From detergeo, to wipe off"). Deterging. (See Abstergentia.) These were medicines formerly supposed to have a specific power in cleansing wounds; but it is now found that proper pus is the most healing application, and that foul sloughs are only separated by exciting the action of the vessels below them.

Deterioratio

(From deterior, worse). Deterioration. The impairing or rendering a thing worse.

Determinatio

(From determino, to fix bounds to). In botany it means the prescribed habit of an herb, as to the number of its leaves, their direction, or insertion, and from which it never deviates. In medicine, an increased action of the vessels of any part, and an accumulation of fluids in it.

Detersorium

(From detergeo, to cleanse). The apartments at baths where the sweat was scraped off.

Detersorius

(From the same). See Abster-sivus.

Detonatio

Detonation, (from detono, to make a great noise). In chemistry it is that noise and explosion which some substances make upon the application of fire, or rather sparks. Detonation is a less degree of thundering noise, and less explosive than ful-minatio. (See Calcinatio, by detonation). As nitre is the cause of most explosions, the word detonation hath been appropriated chiefly to the inflammation of this salt with inflammable bodies; and it is frequently given to those inflammations of nitrous acid which are not accompanied with explosion. Compositions have lately been discovered which detonate by percussion, or even the slightest friction. But this rather belongs to Fulmination; q. v. See Dictionary of Chemistry.

Detractio

(From detraho, to draw forth). See

CaThaeResis.

Detrahens Quadratus

(From the same). See Platysma myoides.

Detractor Auris

(From the same). See Abductor auris.

Detritio

(From detero, to rub off). In a general sense it is taken from trituratio. See Rhacosis.

Detrusor Urinae

(From detrudere, to thrust or squeeze out of.) Douglas divides the muscular covering of the bladder into two distinct muscles: the muscle composed of longitudinal fibres he calls the detrusor urine, which he describes as arising from the prostate gland going round the fundus, and being lost in the gland again; the oblique fibres form a muscle, which he calls constrictor vesicae urinaria, and describes as running obliquely under the other. But Dr. Hunter thinks this distinction merely artificial.

Deunx

See Cyathus.

Deurens Febris

(From deuro, to burn). See Ardens febris.

Deustio

(From the same). See Encausis.

Deuteria

And Deuterinas, (from Deuteria 2679 secundus). A poor kind of wine, which the Latins call lora. Also an adhesion of the placenta.
