Essentiale Sal

See Diureticus sal.

Esthiomenos

(From to eat). Eating, corroding. An inflammation in the skin, attended with a sharp humour, more properly the herpes exedens; or indeed any inveterate ulcer.

Etesiae

(From annus). North-eastern annual rinds. Pliny observes, that the etesian winds set in two days after the dog star rises, and continue forty days. Prosper Alpinus informs us, that the etesian winds blow in Egypt when the sun enters Cancer, and continue almost the whole of June, July, and August; and that at the rising of these winds the Nile rises, and the pestilence ceases. The south wind brings the pestilence; and this wind they call Campsin, from Campsis, a general, who, with his whole army, was suffocated in the sand which was driven upon them by this wind. It is a kind of sirocco, or rather a blast of hydrogenous gas, and not the sand which destroyed the general and his army. It is the simoon of the desert.

Eucoilia

Eudiometer

An instrument employed to ascertain the proportion of oxygen in any given quantity of atmospheric air. We had designed to give a particular account of the various contrivances for this purpose; but they have been found so little applicable to the purposes of medicine, that the detail would not be interesting in a work of this kind. Air obtained from crowded rooms, from apartments where patients affected with the worst fevers have breathed, from the highest mountains, or the lowest valleys, scarcely differs. The principle on which this instrument acts is introducing a substance to common air, which has a powerful attraction for its oxygen.
