A warning

Father Thames (to London): “Typhoid! Lor’ bless you, ma’am! I shan’t do you any harm as long as you keep others from harming me!”

The Maidstone Epidemic Report in the hand of Lady London followed upon an outbreak of typhoid fever in Kent in September 1897 that eventually cost more than a hundred lives. The commission reporting on the causes of the epidemic found fault in the provision of water services by the Maidstone Company, in violation of the Public Health Act of 1878. The outbreak prompted an early successful experiment with immunization among nurses at a local hospital, according to this history.
