Publication:- "On the Contagiousness of Cholera." - *Dublin Med Jour*, 1849, NS xxxv, 1, 243 The Board of Health in London, followed by Dublin, had in a "Circular Manifesto" asserted authoritatively that all experience proved cholera not to be contagious. Graves asserted the contrary, that it was contagious as well to members of the same household as to nurses. But he does not appear to have asserted that the contagion was through the stools to the mouths of infected people.
