(From to break out into a sweat,) hydropedesis, desudatio and mador. Dr. Cullen places this disease in the class locales, and order apoce-noses; and defines it a preternatural evacuation of sweat, one species only of which he considers as idiopathic; ephidrosis spontanea. The rest are symptomatic, of which he enumerates nineteen varieties- seven according to the diseases which they accompany, viz. febrile, febri-cose, hectic,exanthematic, syncopic, scorbutic, saburral; eleven, from the nature of the sweat; lacteal, melleous, vinous,green,black, pale yellow, urinous, bloody, bluish, acid, arenous; and one, from the part whence the sweat is effused, viz. lateral; or, more properly, local. The idiopathic ephidrosis is most frequently the result of debility. Sauvages has three or four times observed men who were afflicted violently with night sweats, that continued for months without fever, bringing on emaciation, debility, and loss of appetite: these were cured by cathartics, the mineral waters styled acidulae, and milk; but amongst boys the disease used to continue long. These sweats seem to resemble Diabetes and Coeliacav passio, q. v. The sweating sickness, said to be peculiar to England and to Englishmen, in every climate, was a fever. See Cullen's Synopsis, and Sau-vages's Nosolog. Methodica.
