from ἐπέχειν, "a day;" a diurnal fever, or a fever of one day's continuance only. In this case, such a heat as attends an excess of wine, a pulse somewhat full and quick, but soft and regular, a slight headache, nausea, and reticentness, are all the symptoms, and which terminate without any sensible evacuation. If it continue unto the third day, it is not a diurnal fever; and if the constitution is very dry, a hectic is to be dreaded.

the Day-fly, a genus of insects belonging to the order of neuroptera. See ENTOMOLOGY Index.
