Note 3 — OUTLINES OF A THEORY OF FEVER.
Reading edition
Perhaps there is no greater enemy to the life of man than cold. Dr. Sydenham ascribes nearly all fevers to it, particularly to leaving off winter clothes too soon, and to exposing the body to cold after it has been heated. These sources of fever, he adds, destroy more than the plague, sword, or famine.—Wallis's edition, vol. I. p. 357.
