Auante Auapse

(From Auante Auapse 1325 to dry). The dry disease. The patient cannot bear either abstinence or eating. Fasting causes a rumbling in his belly, and gnawing pain in his stomach. He vomits up various matters, and after vomiting he is at ease. After eating, there are eructations; an inflammatory heat and redness; a constant feeling as if a painful stool was to be discharged, yet only wind is evacuated; a head-ach; a sense of pricking, as with needles, in different parts of the body; the legs seem heavy, grow feeble and extenuated, and he becomes weak: (Hippocrates). It is not easy from this account to ascertain the real complaint, unless it be an accumulation of sordes in the stomach and bowels. In confirmation of this idea, he prescribed at first a purge, and after it an emetic; he then directs abstinence from fat food, temperance, bathing, unctions, and moderate exercise.


(From Auchmos 1326 to dry). The Latins call it squalor. It is hot, dry, sultry weather.

(From Aura 1329 air, or rather from the Hebrew term aor,) signifies an exhalation, or vapour, which arises from mephitic caves. The chemists mean by it a certain fine and pure spirit, found in every animal and vegetable body; but so subtle as only to be perceptible to us by its smell.

Aura epileptica. A gradual sensation, like air ascending from some determined part of the extremities upwards, occasioning an epileptic attack. In the Ephem. Nat. Cur. An. 3. Obs. 336; and in a treatise of Galen on an epileptic boy, there are evident examples of an epilepsy per consensum ab aura adscendente.
