febris

Yet my judgment is, be it spoken without offence of the learned physicians, that the disease was Febris ardens, a burning fever.

Morton, writing in 1692-94, clearly points to the same fever under the name of worm fever (febris verminosa).

It meant simply acuta, the adjective of febris acuta made into a substantive.

Febris epidemicae cerebro et nervoso generi potissimum infestae, anno 1661 increbescentis descriptio, in Pathologia Cerebri, Cap.

This fever, with strong pulse without inflammation, or febris irritativa, described in Class I. 1.
