"Dr. Fourcault . . . [believes that] cholera is never contagious except when combined with typhus,--a law which, he states, obtains also with regard to yellow fever and plague."
Dr. Fourcault asserted that the instance of the typhoidal form of cholera at the Isle of France in 1829 described in this selection is "an exceptional fact which rather confirms than invalidates his general conclusion of the non-contagiousness of cholera."
