Note 641 — BOOK I.—OF THE EPIDEMICS.

The causi or ardent fevers, it is worthy of remark, began this season in spring, but were not of a fatal character until autumn. In modern times the bilious remittent fever has uniformly been found to be most aggravated in autumn, and hence it has been named by some authorities the autumnal remittent fever. See the works of Sydenham, Pringle, Monro, and Cleghorn. Monro mentions that he seldom saw it in spring, but that it is common in the neighborhood of London towards the end of summer and beginning of autumn. All these authorities are agreed that it is of a highly bilious nature.
